Good to know
Good to Know
- Bangkok's dry season (Nov–Feb) offers the most pleasant weather, though it is peak tourist season and crowds/prices are highest
- April is brutally hot and best avoided unless you enjoy extreme heat; late afternoon/evening indoor activities (malls, spas) are essential
- During monsoon season (Jun–Oct), rain typically arrives in short, intense afternoon/evening bursts rather than all day; mornings are usually dry and good for sightseeing
- September is the wettest month and can see occasional flash flooding in low areas and small alleys; major roads drain faster
- Humidity is consistently high year-round (60–79%), making heat feel more intense; the lowest humidity occurs in the dry season
- Typhoons occasionally affect Thailand (Jun–Dec) but Bangkok is geographically sheltered and has not experienced destructive cyclones in recent centuries
- Pack light, breathable clothing year-round; an umbrella or rain jacket is essential May–October; sunscreen and sunglasses are critical year-round
