Hottest month of the year. 38-40°C in Bangkok. Songkran (Thai New Year) shuts the country down for 3-5 days mid-month.
Rain: Building (30-90mm)
Sea: Mostly calm Andaman, calm Gulf
Lean into Songkran or avoid it entirely — there is no middle ground. Bangkok shuts down. Beach destinations stay functional.
Plan Songkran in Chiang Mai or Bangkok if you want the full experience. Otherwise Koh Samui or Phuket for calm beach time.
