Insider timing tips
- •The 'burning season' (roughly Feb-April) can severely degrade air quality, making outdoor activities unpleasant and potentially harmful. Check air quality indexes before booking.
- •While the rainy season (May-October) has fewer tourists and lower prices, heavy downpours can disrupt travel plans and limit access to some natural attractions.
- •November is a sweet spot, offering excellent weather and major festivals, but it coincides with peak season pricing and crowds.
- •The shoulder months of October and February offer a good balance of decent weather and slightly fewer crowds than the absolute peak.
- •Songkran in April, while festive, is an intense experience with widespread water-based celebrations that can make getting around the city challenging.
