March marks the transition from the dry season to the hot season in Thailand, with temperatures rising to around 25-35°C (77-95°F).

This month is ideal for visiting Thailand’s world-famous islands such as Koh Samui, Koh Tao, Koh Phi Phi, and Koh Lipe. Whether you're snorkeling over coral reefs, swimming in turquoise waters, or simply relaxing on powdery white beaches, March offers a perfect setting.

April is the hottest month of the year in Thailand, with temperatures often soaring above 35°C (95°F), especially in central regions like Bangkok and Ayutthaya. Despite the intense heat, it's also one of the most exciting times for a Thailand vacation thanks to Songkran, the Thai New Year and world-famous water festival.
Taking place from April 13-15 (and sometimes longer in cities like Chiang Mai or Pattaya), Songkran is a time when locals and tourists alike hit the streets for joyful, all-out water fights that symbolize washing away bad luck and welcoming a fresh new year. Beyond the splashy fun, there are also beautiful cultural traditions like temple visits, Buddha image bathing, and giving blessings to elders.

May is when Thailand begins to transition from the hot season to the rainy season. The weather is still quite hot (26–34°C) but there are some light rains in the afternoon. However, the rain is not much so you can still go out comfortably.
Because it is the time when there are fewer tourists, airfares and hotels are cheaper, very suitable if you want to have a budget Thailand vacation. The beaches in the South such as Koh Samui are still beautiful, while Phuket starts to have more rain.
