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)
