Which parts of Thailand are driest in April?

Koh Samui and Koh Phangan are inside the dry window in April.

Is there burning season smoke in Thailand in April?

Chiang Mai, Pai and Isaan (Northeast) are inside the burning season in April, when fields and forest are cleared inland and air quality drops in the weeks the weather is otherwise at its best. It is felt in a hard session rather than on a beach day, and it is the reason a dry reading inland in April is not the recommendation it looks like.

Month 04 of 12

April

The hottest month of the year, Songkran in the middle of it, and the smoke still sitting inland.

In April, train in Koh Samui and Koh Phangan. Think twice about Bangkok, Isaan (Northeast) and Chiang Mai.

April is decided by heat rather than by rain. It is the hottest month almost everywhere and it is hotter inland than on the water, which is the opposite of the way the rest of the year runs. Bangkok in April is a city that holds the heat rather than releasing it overnight.

Songkran falls on 13 to 15 April and the country stops for it. What a specific camp does that week is a question for that camp and not something to assume from a calendar, so if those dates are the trip, ask the gym directly before booking around them.

The southern Gulf is the quiet answer. Samui and Phangan are in the last month of their dry window while the Andaman coast is coming out of its, which makes April the month the two coasts briefly swap places.

Dates that can move

Most trips can move by a fortnight and a fortnight is the difference between two of these pages. Both neighbours are worth reading before the dates are booked rather than after.

All twelve months

The month before
March
Dry everywhere on paper, and the single worst month of the year to train inland.
The month after
May
The month the map flips. The southwest monsoon arrives and the Gulf becomes the dry side of the country.
