What to wear in Bangkok in May
A practical May packing list for Bangkok starts here: pack very light, breathable clothing, sun protection and shoes that handle heat well. Add a compact umbrella or light rain jacket because wet weather is common enough to affect sightseeing.
Travel takeaway: Sightseeing is possible, but the heat can shape the pace of the day; early starts, shade and indoor breaks help.
