Insider timing tips
- •The 'burning season' (roughly February-April) can cause significant air pollution, particularly affecting visibility and outdoor activities.
- •While the wet season (May-October) brings rain, it also means lush landscapes and fewer tourists, offering a more serene experience.
- •November is prime time due to the end of the rains, pleasant temperatures, and major festivals like Loi Krathong and Yi Peng.
- •Accommodation and flight prices surge dramatically during the peak season (November-February) and festival periods; book months ahead for these times.
