Hot Season

The hot season runs from March through to May, the heat wave will be starting higher temperature a bit in the mid-February. This short period lasts from March to May. And we are very sure, you will see 40°C at end-April. In Chiang Mai and Northern Region air pollution can be a problem this time of year. But the major festival has been popular time for tourist in April to join with the local people celebrate Songkran Festival [Thai New Year].

You have to have a tips to travel this summer along in Thailand. It can be make you heat up and knowing about heat stroke treatment happens when your body gets too hot.

Rainy Season

The longest season is characterized by somewhat cooler temperatures from 22°C to 35°C, well and rain. Throughout the country, the rain only lasts for an hour or two each day by region. It can be a longer downpour when they have got a new tropical depression. The showers typically drop temperatures during the rainfall and sometimes up to a day afterward.

But this is a season that I love and especially when it’s just sprinkling. Everything green surrounding and no more people go by. The rain make them calm and cool. And cover me up or take me out the messy day.

The rain isn’t constant in the early months of the period as it will rain for one or two hours and then dry out. September and October is the late in a monsoon season. When the rains are heaviest and longer. Be aware that flash flooding can occur.

However, carry an umbrella, raincoat or head inside for traveling you can still enjoy a great holiday in the Thai rainy season.

Cool Season

The most popular time to visit Thailand is when it’s coolest, normally runs between November and February. You can expect temperatures between 18°C to 30°C with sunny and dry days but will still feel hot to most visitors. For Thai people is a good weather that they like.

Much of the country does experience a short cold snap for a week or so in December, especially in the north such as Chiang Mai, Chiang Rai and Mae Hong Son and northeast where it can get quite chilly.

There will be drop to 10°C in the morning ( not everyday ). It’s too cooler for Thai people but they love it to visit and enjoyable this season. For the foreigners, I hope this temperatures range make you happy. The temperatures will be rise up to 20°C And in the day time will be fine and 30°C in the afternoon.

Notes; The temperatures will be dropdown a bit more 1-5 °C where you stay in the jungle and high mountain.

Whenever you’re visiting be sure to bring a lot of good sunscreen. The sun can be quite intense. But at least there is typically a lot of it to enjoy.

This season can vary from year to year. Out of these times there may be some bargains to be had if you are prepared to put up with the risk of rain.

In each region of Thailand, the weather is different even if in the same season. You will have to know the different temperatures in each zone and where should to go. I have some ideas for example to traveling all year round

* Pronounced “ra-nong”
Notes; * Thailand has 2 provinces looking like the same pronounced, one is Rayong ( ra-yong ) in the east coast next to Pattaya and another one is Ranong ( ra-nong ) on the Andaman Coast above Phuket.

In the south, on the Andaman Sea and west side (including the Andaman islands) this can start as early as Nov or Dec, the rains don’t end until late November. Although it rain begins in June and runs as late as October, when the temperatures begin to cool slightly.

On the Gulf Coast, the popular destinations Samui, Phangan and Koh Tao this can start as early as June, although it rain begins in November and runs as late as May.

Why do they travel longer in southern

Yes, it seem to be the same but it is a difference weather in southern Thailand. There are only 2 seasons “dry and wet” and changing between east coast and west coast. The weather zone start from part of Prachuap Khiri Khan Province and down to Malaysia.

East coast or Thailand Gulf dry season start in Jun – Oct and wet season start in Nov – May. West Coast or Andaman Sea dry season start in Nov – May and wet season start in Jun – Oct. That is a reason why they do travel longer and get the best time to visit more in northern Thailand.

Mar – Sep the daylight hours will be longer, resulting from the earth’s changing position with regard to the sun. Thailand has no snow but has some hail in some places when the weather change between cool and hot season during Mar – Apr. And there are green trees and blooming flowers all year.

Hope you enjoy and happiness holiday trip whatever season that you like in Thailand.

See you soon.
