Weather details in may

The climate in Thailand in throughout May marks the beginning of the rainy season, with a sometimes sudden increase in precipitation throughout the country. The thermometer stops its rise of previous months, but the heat coupled with ambient humidity can sometimes be oppressive in non-coastal areas. Tourism slows down and some seaside resorts close until the return of the dry season and its milder weather.

Bangkok and the Center of Thailand in May

Bangkok and the Center of Thailand in May face the true beginning of the wet season. If visiting the capital at this time, expect frequent rains (a fortnight in the month) but a heat that is always present for an average of 30° C in May. Temperatures can warm up to 40° C. The rest of the center observes temperatures that are still very high: 34-35° C and air conditioning is more necessary than ever.

East of Thailand in May

The eastern region does not escape the monsoon, and the northern Gulf coast also receives its own precipitation, up to a fortnight for Koh Chang. As a result, tourism on the island is becoming rarer. Temperatures reach an average of 28° C over the month, allowing for a sea at 30° C, but there are peaks that reach 35° C and more. For less dense showers, prefer Koh Samet and Pattaya.

Northern Thailand in May

Though May be part of the warm season, northern Thailand cools by about 2 degrees for an average temperature of around 28° C (with temperature peaks above 33-34° C). Thanks to regular rain and thunderstorms, the area observes a breathable atmosphere, but hikers will have to wear waterproof clothing if they wish to participate in the month of the Buddha (Chiang Mai).

Northeast Thailand in May

May is the last month of relative drought before the so-called hot and humid season. Count twice as much rain as in April, but expect a very high temperature. The thermometer easily reaches 33-34° C and climbs to 40° C, especially in the province of Udon Thani.

Southeast Thailand in May

The southeast also receives its share of clouds and rain, that are more abundant (double compared to April), with a decreasing duration of sunshine (from 8 hours to 6 hours daily for Koh Samui). On the other hand, temperatures do not drop: the thermometer sails between 26 and 33° C with a sea at 28-30° C. For a less rainy day, prefer beach resorts on the northwest coast of the Gulf of Thailand.

Southwestern Thailand in May

The southwest experiences a notable increase in rainfall and a slight decrease in temperatures throughout May, but the climate remains very hot with an average of 29° C on Koh Lanta and Phuket. Count ten days with showers on Koh Lanta and nearly twenty in Phuket, but the sun remains present. These weather conditions announce the low tourist season and result in the closure of a few resorts; the others offer interesting discounts to maintain their activity. It's a time to enjoy.

perfect weather good tolerable bad very bad

warning in may the weather is not the same depending on the city and regions of the country.

That month is not the best month to visit Thailand. The weather in Khao Sok National Park, Khao Lak national Park, Bangkok, Burinam, Chiang Mai, Udon Thani, Uttaradit, Ayutthaya, Sukhothai, Krabi - Ao Nang, Pai, Ubon Ratchathani (Isan), Phuket, Koh Chang, KhaoYai National Park, Khon Kaen, Chiang Rai, Chanthaburi, Pattaya and Mae Sot is ok but correct. The sun is not there all the time and you might make you wet by rain frequently. Nevertheless, if you don't plan a beach and sun travel in Thailand but rather discovery of heritage or walking, this climate may be good enough for you. In addition, there are definitely fewer tourists at this time of year.

It's even worse in Hua Hin, Ko Lipe, Koh Phangan, Sakhon Nakhon, Koh Tao, Koh Phi Phi, Ko Samui, Songkhla and Koh Lanta and surrounding areas where the climate is very bad. It is not advisable to visit these areas this month.
