Weather in May

May is a month of contrast. The southwest (Yala) monsoon fully takes over the west and south coasts with daily heavy rainfall. Meanwhile, the east coast begins its dry season with perfect sunny weather. The central highlands remain accessible but wet. May marks a significant seasonal shift — it's the worst month for traditional beach destinations but the best for east coast discoveries.
