Take all required precautions, as unprotected skin and eyes can burn in minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.

Occasionally, air temperatures go beyond these values, but this happens rarely. Average temperatures for this period indicate that Bangkok in Thailand is slightly warmer than the capital of Vietnam in May.

Regarding the rise of temperatures, we could consider May the first month of the hot season in this destination. Although most of the day feels warm, this interval shortens at a rapid rate in the course of the month. The hot interval initially lasts approximately 3 hours, from 2 pm to 5 pm. At the end of May, the duration of this interval is already 9 hours, lasting from around 11 am to around 8 pm.

Sunshine Hours

The number of sunshine hours in the city is higher this time of year than in the previous period. On average, Hanoi receives around 5 hours of sunshine per day on average during this month. Still, cloud cover continues to dominate over the city, despite higher chances of sunny weather. In general, around 32% of daylight hours constitute sunshine while the remaining 68% is a share of overcast or mostly cloudy sky.


With the arrival of May, the rainy season officially begins in this destination in Northern Vietnam. The amount of rainfall doubles in comparison to April, with the city receiving around 190 mm/7.48 in of precipitation on average. The number of wet days remains virtually unchanged in regard to the previous month, usually ranging between 14 and 18 days. Drizzle is the most common form of rain this time of year, but torrential downpours are becoming an option, too.

The chances of a rainy day increase at a fast rate from the beginning of May toward the end of the month. According to statistics, May 1 has 29% of chances to be a wet day. This probability rises up to 46% on May 31. Days are usually much rainier than nights, with the highest chances of precipitation around noon. Evenings around 7 pm and 8 pm are the least rainy periods of the day.

Wind Speed

The wind speed gradually decreases as time passes during May in Hanoi, the Vietnamese capital. At the beginning of the period, the average speed of the wind is 3.4 m/s. By the end of the month, it drops to 2.9 m/s. Still, moderate breeze substitutes gentle breeze at times. The windiest time of the day is around 4 pm, when the strength of the wind rises up to 4.4 m/s. Around 4 am is the calmest time of the day, with the speed of wind decreasing down to 2.2 m/s.


Hanoi, the capital city of Vietnam, becomes a very humid place this time of year. The average relative humidity is 69%. The chances that any day will be muggy, oppressive or miserable range between 92% (May 1) and 98% (May 31) from the statistical point of view.

Sunrise and Sunset

Days become longer in this destination during May. On May 1, the sun rises at 5:26 am, and sets 12:54 hours later, at 6:21 pm. On May 31, sunrise takes place at 5:14 am while sundown occurs at 6:33 pm, which gives the city 13:19 hours of daylight.

Extraordinary Weather Occurances

With the arrival of the rainy season, certain parts of Hanoi tend to experience occasional flooding. Yet, this possibility is lower in May than during subsequent months since heavy showers are still less numerous. Also, the season of typhoons begins in the second half of May, but these unwelcome occurrences usually take place in summer in this destination.

The location of the city lies in the area where earthquakes do happen. Yet, none of particularly destructive ones affected the capital of Vietnam in a last couple of decades.

Things to do in Hanoi in May


The traditional ball scrambling festival takes place in the village of Thuy Linh, in the Hoang Mai district of Hanoi.

Also, return at night to enjoy interesting illumination

Shark Tank - Saturday Night Live


The likelihood of rain increases throughout the month and throughout the country as Vietnam edges into the hot wet season. Pack rain gear and insect repellent along with your summer clothing.

In the northern hills, Ha Giang starts to see a good deal of rain while further west the Sapa region and Mu Cang Chai are still predominantly and delightfully dry, with an average temperature of around 68-76 (20-24°C). The Central Vietnam coast is shielded by the Truong Son mountain range and in the summer months (May through September) receives relatively little rain, while the Central Highlands begin to feel the effect of the southwest monsoon. Hence, the beaches between Hue and Nha Trang are still tempting, with average temperatures of around 86°F (30°C).

By comparison, southern Vietnam, especially the Mekong Delta, is typified by hot, humid weather and plenty of rainfall (but, fortunately, May is slightly cooler than the stultifying heat of April). As summer progresses, heavy rains can cause disruptions, requiring flexibility along with sound raingear. However, you can still expect plenty of dry spells, And much of the rain falls in short, heavy afternoon and evening downpours.

Crowds & Costs

Early May marks the end of the all-rounder months, with most parts of the country still attractive. For example, you can still enjoy the best beaches in glorious sunshine but without the crowds of earlier in the year. Only three months see fewer visitors than May, although there are regional variations, with much of relatively dry Northern Vietnam (and even the beach resorts of Central Vietnam) still popular.

Vietnamese families will mostly stay at home, awaiting the school holidays that begin in mid-June, so you won’t be sunning shoulder-to-shoulder with locals on popular beaches like Nha Trang or Quy Nhon, and top museums and tourist sites in cities won’t be crowded either. The exception is the April 30-May 2 holiday when a vast number of Vietnamese hit the road for sightseeing that for many locals extends to four days.

One upside: prices of tours and accommodations drop or become easier to negotiate in May. The downside is that while there are fewer travelers, the onset of rainy season brings more mosquitoes.

Where to Go

At the beginning of the month, during April 30-May 2 holiday, city-folk head out of town en masse for a mini vacation. Traffic congestion in the main cities eases, and there are relatively few locals touring the museums and most popular tourist sites. This is a great time to explore Hanoi, Hue and Ho Chi Minh City (at this time of year the temperatures in all three cities averages 84°F/29°C), focusing your time on the main sites and air-conditioned museums. But come prepared for rain!

Since Central Vietnam witnesses much less rain in May than other parts of the country, this is a great month for time on its beach-trimmed coast. The white sandy beaches of Nha Trang and, further north, Qui Nhon are relatively tranquil and the warm water of the South China Sea is generally calm. For a little more seclusion, head to Lang Co Bay, a quiet crescent-shaped beach that is mercifully as-yet undeveloped. Plus, you can combine beach time with cultural exploration in the area’s two UNESCO World Heritage Sites, Hue, and Hoi An.

In Northern Vietnam the terraced rice fields are at their most beautiful—lushly green and brilliant yellow-gold with a new rice crop, twinkling in May—the “falling water season”—with cascades of water running from terrace to terrace. The most photogenic places include Mu Cang Chai, Pu Long, and Trang An at the edge of the Red River Delta.

What to Do

May is a great time to enjoy watersports in Nha Trang or one of the other Central Vietnam beach resorts. Nha Trang and similarly well-developed resorts offer a medley of activities, from sea-kayaking, water-skiing and kite-surfing to parasailing and scuba diving. In fact, Nha Trang is an excellent place to get an international scuba-diving certificate (PADI), as the shallow waters surrounding the islands of Nha Trang are not intimidating to beginners, and also offer a decent snorkeling experience.

Take a hike in Cuc Phuong National Park. Wildlife lovers and travelers seeking active adventure will find Vietnam’s oldest national park (and still the country’s largest nature reserve) rich in biodiversity, with more than 85 square miles (220 sq km) of tropical rainforest, plus plenty of hilly (and often slippery) trails to get the adrenalin pumping.

Most well-known for its April-May “butterfly season,” Cuc Phuong is also home to more than 300 bird species and almost 90 species of mammals, including critically endangered endemic gibbons, langurs, and loris. Count yourself lucky to see them in the wild, but you’re guaranteed eye-to-eye encounters at the park’s Endangered Primate Rescue Center. Wear good hiking shoes, apply mosquito repellent before entering the park, and take plenty of bottled water to stay hydrated.

“Another fabulous trip”

28 June, 2020

This was our third trip with Selective Asia and it was just amazing. They don’t just provide an excellent trip but take the trouble to really get to know their clients and can make recommendations and suggestions that will enhance an already great experience. It’s the tiny details that can make the difference between a good holiday and an amazing experience. Karl knew our time limitations and managed to create a great itinerary that allowed us to make the most of our time in India but also allow downtime to relax. The hotels he suggested were perfect and he was always honest about what would be the best place for us to be. Our guides and drivers were perfect and a great part of the SA team. I would never travel to Asia with any other company.

“Faultless customer service”

4 June, 2020

Firstly how strange it is to review a holiday company for a holiday you never got to go on! That said I have to say this wasn't our first trip with Selective Asia, our honeymoon in 2011 was also booked through them and was amazing, from booking to completion everything was seamless. Fast forward 9 years and 2 children later we wanted to book the "trip of a lifetime" and Selective Asia was foremost for our booking. I actually went to multiple bespoke agents and Selective were the only ones who stuck to budget, considered who I was travelling with (2 young children) and actually listened to what we wanted out of our trip. Their advise and suggestions were well considered - whilst we may be "experts" on our children - we've never travelled long distance with them and the recommendations from Andrew, our consultant were exciting for us as parents, giving us the potential to feel like we were having the adventure we craved - but keeping the kids engaged and part of it. We came up with a fabulous itinerary with beautiful, individual places to stay and interesting places to visit. Everything was set. Roll on to March and with 3 weeks to go - everything changes in the world and Coronavirus changes the game. This is where things could have gone wrong - but I can't fault Andrew at Selective. He has kept us informed every step of the way and his insightful advise has just reassured me that their are companies out there (unlike my insurer!) that will act responsibly and fairly. Anyone with an internet connection can sell you a flashy holiday but the true measure of any company is how they treat you when things go wrong - and Selective Asia have been faultless in a situation that was entirely blameless. When the world opens up again, Selective Asia won't just be my first port of call, they will be my only and I would urge anyone to support this superb, small and ethical company,

“Fantastic trip to Indochina”

1 June, 2020

From the time I first contacted Selective Asia, when I had a very useful conversation with Aaron about the type of trip we had in mind, to the very end of our holiday and return home, they provided excellent service. Aaron worked hard to create an itinerary that would suit us, we were very happy with the hotels and tours they booked for us, and on the whole were more than satisfied with the local guides.

“Fantastic company, great holiday and amazing service when it all went wrong”

18 May, 2020

We booked a holiday of a lifetime to Borneo, which was extremely well planned, accommodation was great and very much enjoyed it until the Malaysian government closed the country due to Covid and we had 24 hours to leave the country. SelectiveAsia were responsible for all travel while in Malaysia but I’d booked the flights to and from the country through BA. While Nick and his team were working at 1am in the morning to get us out the country, BA wouldn’t answer the phone and refused to get us home. The SelectiveAsia team managed to get us from the middle of the borneo rainforest to KL and home within 24 hours, were constantly in communication throughout. While we were already very happy with the holiday, it is times like this when you realise why local travel agents are so important! Nick and his team were doing everything they could for us and while we were happy with the holiday before this event. We will now ensure every trip we make to Asia is with this company.

“Forceibility Quarantined in Vietnam - would I use again!”

5 May, 2020

Hell yeah! Booking: a pleasure working with Maryisa to exactly specify the trip that meet our exact wishes and needs. Once this was all confirmed we had access to a great app that had all the information required to make a stress free trip. Always willing to answer any little question. Quarantine Support: There was nothing that Nick or the team could have done about this it was simply the Vietnese overnment being ultra cautious. HOWEVER whist most tour operators abandoned their quests Selective ensured we had a rep onsite at the facility who would bring us food and drink and even a pack of cards. Nick was always available day and night to answers questions and update us on what they were doing to support our early release. Post Quarantine Support: Once back in the UK unlike many of the big tour operators Selective managed to refund a significant portion of our trip which meant insurance paid out on the rest quickly. Other tour companies could learn a lot from Selective! Horrible experience as we lost our dream holiday to Vietnam but this wasn't Selective fault and they did they best to help us.

“A wonderful holiday incorporating the richness and diversity of India!”

4 May, 2020

This is the second holiday we have enjoyed with Selective Asia. Right from the initial contact the company is very helpful, the team listen to what each customer wants in terms of an overall experience and tailor their suggestions to the customer’s requirements, creating the best experience they can. The team have an excellent knowledge of each destination and do include unusual and interesting details to the itinerary which allows for a rich experience of the culture and daily life of the country in question. The team also pay attention to each customer’s budget and tailor make the holiday accordingly. They are also very mindful of the effects tourism can have on the environment and aim to lesson its impact as much as possible.

“Excellent customer service. Nothing was too much trouble.”

30 April, 2020

Everything about Selective Asia is how customer service should be. Other travel companies could learn from them.

“Vietnam trip 2020”

18 March, 2020

Great organisational skills and extremely responsive and supportive when airline cancelled one of our flights 24 hrs before we departed

“A comprehensive, informative, personalised, enjoyable tour of North India”

18 March, 2020

A carefully planned trip through North India personalised using quality accommodation transportation and guides. Thoroughly recommend this company.

“The perfect way to explore Asia”

13 March, 2020

Selective Asia is the perfect way to see Asia. They carefully listen to your requirements and needs, add a considerable amount of value with their experience and knowledge of the location, then craft you the perfect holiday. From there on your mind needs to just absorb the culture, surroundings and above all have fun. They take care of the bookings, the logistics, their attention to detail is second to none. Absolutely no hesitation in recommending them to anyone who wants to explore Asia.

“A holiday which we will remember forever. Attention to detail was excellent”

12 March, 2020

“Fantastic Cambodian holiday”

12 March, 2020

Excellent from enquiry stage to arriving home. The itinerary was perfect with plenty of time for thorough exploration of Angkor Wat and other very interesting temples, great excursions to discover village and town life with local interaction in Siem Reap and Phnom Penh. Lunch with a local village family following a ride on an oxen cart was particularly memorable. Guides were great. Finishing at a fantastic beach resort. Hotels were expertly chosen and perfect for us.

The holiday itself went like clockwork, guides and drivers were good and on-time. Boats were waiting for us and all the accommodation arrangements went well. Things can go wrong and when something did, S.A. dealt with it very professionally.

“Looked after by Selective Asia for the 2nd trip.”

12 December, 2019

From first contact to the trip itself, first class service from anyone you make contact with. The itinerary is created together with you and hotel and activity selections being tailored exactly to our needs. As the specialist has visited the countries they are able to offer insight and tips for an even better experience.

May weather forecast and climate
Ho Chi Minh City, Vietnam

Weather in May

The last month of the spring, May, is also a hot month in Ho Chi Minh City, Vietnam, with average temperature ranging between min 26.9°C (80.4°F) and max 34.1°C (93.4°F).


In Ho Chi Minh City, the average high-temperature is practically the same as in April - a hot 34.1°C (93.4°F). In May, in Ho Chi Minh City, the average low-temperature is 26.9°C (80.4°F).

Heat index

In May, the average heat index is calculated to a life-threatening hot 48.2°C (118.8°F). Beware - heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Note that heat index values are valued for light wind and location in the shade. With the exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel', 'apparent temperature', 'felt air temperature', or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (clothing, wind, differences in body mass, height, and shape). Be aware that direct exposure to sunlight increases heat impact, and may raise the heat index additionally, by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.


The average relative humidity in May is 72%.


In Ho Chi Minh City, during May, the rain falls for 27.8 days and regularly aggregates up to 139mm (5.47") of precipitation. Throughout the year, in Ho Chi Minh City, there are 241.8 rainfall days, and 1283mm (50.51") of precipitation is accumulated.


In Ho Chi Minh City, the average length of the day is 12.6h.


In Ho Chi Minh City, the average sunshine is 10.3h.

UV index

Months with the highest UV index are January through December, with an average maximum UV index of 7. January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from the exposure to the Sun's UV rays for average individuals.
Note: The daily maximum UV index of 7 in May interpret into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
