Thailand Weather in March

March sees the arrival of the Thai summer (the hot season); expect the mercury to rise above 35 degrees Celsius in the afternoon. The heat in cities like Bangkok and Chiang Mai might feel oppressive and stifling. The warmest part of the day is best spent in the shade, in air-conditioned spaces or in the sea. Oh, and make sure you apply enough sunscreen!

What to expect of the weather in Thailand in March

Bangkok and the surrounding area

The difference in temperature compared to last month is especially noticeable in Bangkok. Expect temperatures during the day to rise above 30 degrees Celsius. Look for a place in the shade during the afternoon and make sure you book a room with air conditioning, as nights are also very warm. It very rarely rains in March.

Ayutthaya – Soak up the culture and visit historical temples.
Bangkok – Thailand’s capital blends old temples with ultra modern skyscrapers.
Kanchanaburi – Town brimming with nature and history.
Khao Yai National Park – The oldest nature reserve with wild elephants.
Koh Samet – White sandy beaches, only three hours from Bangkok.

Koh Samui and the southeastern Gulf of Thailand

The entire country will see the mercury rise, including the southeastern Gulf of Thailand. Expect cloudless, sunny days with the occasional breeze. Book a hotel with a swimming pool or close to the beach, so that a dip in water to cool down will never be too far away. This month sees the end of this region’s high season as it gradually gets less busy.

Koh Phangan – Serene island that hosts large beach parties.
Koh Samui – Popular island with long beaches and luxury accommodation.
Koh Tao – Thailand’s number 1 island for snorkeling and diving.

Chiang Mai and the North of Thailand

Temperatures in the north of Thailand will start to get very high. Not only is it very hot, it’s also very dry, with Chiang Mai and its surroundings areas getting covered by thick layer of smog. Farmers during this time of year, as a means of preparing their soil, set alight their land, which doesn’t exactly improve circumstances. It’s best to avoid the north of Thailand during this period.

Koh Chang and the Eastern Gulf of Thailand
