⚡ Quick Facts About May
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.
East Coast (Ideal)
West & South Coast
Hill Country
The east coast shines in May with clear skies, warm temperatures (28-31°C), calm seas, and minimal rainfall. Perfect conditions for swimming, snorkeling, diving, and water sports. The west and south coasts experience 300mm+ of monthly rainfall with afternoon thunderstorms lasting 2-3 hours. Despite heavy rain, humidity is moderate at 70-80% due to ocean breezes.
