Best: Dec-Feb, Apr · Great: Nov · Apr for Songkran
A classic dry-summer rhythm shapes the year — hot, largely rain-free stretches around April giving way to milder, wetter conditions by September. In December, expect highs around 31°C with rain on roughly 1 day of the month.
Songkran (April) — Thailand's water-splashing New Year festival takes over the streets April 13–15 — hot season, but one of the most popular times to visit for the celebration itself.
The Grand Palace and Wat Pho's reclining Buddha anchor the old city, best visited early to beat both heat and crowds. Chatuchak Weekend Market is enormous and genuinely worth a half-day, and a longtail boat ride through the Thonburi khlongs (canals) shows a quieter, more residential side of the city. Chinatown's street food stalls come alive at night, and a day trip to Ayutthaya's ruined former capital is an easy train ride away.
Try pad thai and tom yum soup from street stalls, alongside Thai iced tea or a local Singha or Chang beer.
