30 days (slow travel)

Packing & health

Plan B (if weather turns)

• Heat plan: early mornings + late afternoons; midday indoor
• If north AQI is poor: shift days to Bangkok markets, malls, museums

Common mistakes

• Underestimating March heat and walking all day without breaks.
• Trying to cram too many outdoor activities into midday.
• Planning tight island transfers without buffers.
• Going north without flexibility if you’re sensitive to air quality.

How we verify month guidance

Thailand weather and seasons shift year to year, so we treat month pages as “planning ranges” and re-check the most volatile items regularly:

• Season definitions and transitions: Thailand.go.th seasonal guidance and official announcements
• Weather advisories: Thai Meteorological Department warnings (especially wind/waves for island travel)
• Festival timing: Tourism Authority of Thailand pages (many festivals follow the lunar calendar)
