Plan B (if weather turns)

• Bangkok: malls, museums, food tours, river day
• Beach base: spa day, cooking class, viewpoint hikes

Common mistakes

• Trying to “do it all” in 7 days (too many transfers).
• Booking beachfront hotels late and paying peak prices.
• Choosing a base far from transport then losing time to commuting.
• Ignoring that popular day tours fill up quickly in peak season.

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)
