Dry (≤5 days) – Sunny skies, minimal rain. Ideal travel weather.
Light (6–8 days) – Occasional brief showers, mostly sunny. No trip impact.
Moderate (9–11 days) – Frequent afternoon downpours but mornings usually clear.
Wet (12+ days) – Heavy monsoon rains. Usually 1–3 hour bursts, not all day.
💡 Rainy season reality: Thailand’s rainy season (May–Oct) doesn’t mean all-day rain. Expect 1–3 hours of heavy afternoon downpours then sunshine. The Gulf coast (Koh Samui) has a different cycle—wettest Oct–Dec. Phuket’s Andaman coast is wettest May–Oct with rougher seas.
