Month-by-month guide to Bangkok weather, Songkran festival, crowds, and when to visit Thailand's capital for the best experience.
Bangkok is a year-round destination, but the difference between seasons is significant. The cool dry season (November–February) is when Bangkok is at its most comfortable. The hot season (March–May) is intense. The wet season (June–October) brings daily rain but also fewer tourists and lower prices.
Bangkok's Three Seasons
Cool & dry (November–February): Best weather — 25–32°C, low humidity, minimal rain. Peak tourist season.
Hot season (March–May): 33–40°C with high humidity. Songkran (Thai New Year) in April is a highlight despite the heat.
Wet season (June–October): Daily afternoon rain, high humidity, occasional flooding. Fewer tourists, lower prices.
Month-by-Month Breakdown
November–February: Best Season
Weather: 25–32°C, low humidity, clear skies
Crowds: High (peak December–January)
Hotel rates: Peak
Highlights: Loy Krathong (November), Christmas/New Year
The cool season is Bangkok at its best. Outdoor temples, markets, and rooftop bars are all comfortable. December–January sees the highest hotel rates and most tourists. November is the best-value month — excellent conditions with shoulder-season prices.
Best for: First-time visitors, families, anyone wanting comfortable sightseeing.
March–April: Hot Season
Weather: 33–40°C, very high humidity
Crowds: Moderate (Songkran spike)
Hotel rates: Moderate (Songkran premium)
Highlights: Songkran (13–15 April) — Thailand's water festival
March is Bangkok's hottest month. Outdoor sightseeing is best done early morning or evening. Songkran (13–15 April 2026) transforms Bangkok into a city-wide water fight — one of Asia's most exhilarating festivals. Hotels around Silom and Khao San Road fill up weeks in advance.
Best for: Festival travellers (Songkran), those who don't mind heat.
June–October: Wet Season
Weather: 28–34°C, daily afternoon rain, occasional flooding
Crowds: Low
Hotel rates: Low (20–35% below peak)
Bangkok's wet season means daily afternoon downpours — usually 1–3 hours — followed by clearing skies. Mornings are often fine. October can bring heavier rain and occasional street flooding. Indoor attractions (Grand Palace, museums, malls) are unaffected.
Best for: Budget travellers, repeat visitors.
