What to Wear in Bangkok
Thailand · 4 monthly packing guides
Bangkok dresses for heat (35°C / 95°F+ year-round), humidity (75%+), and the temple dress code. The Grand Palace and major wats strictly enforce covered shoulders and covered knees — no exceptions, not even scarves as shoulder cover-ups. Monsoon season (May-October) brings 1-2 hour afternoon rain bursts; quick-dry fabrics beat cotton. Slip-on shoes save time at every temple entrance and restaurant threshold. Sukhumvit and Thonglor are cosmopolitan and dressy; the old city dresses modestly.
Choose your month below to match your layers and shoes to the weather. Across the months covered, average daily lows reach 26°C / 79°F in June; average highs reach 35°C / 95°F in May.

No. They are monthly climate averages for planning, not temperatures promised for a particular day or hour. Check the local forecast close to departure and adjust your layers and rain protection. The source, station and averaging period are listed for each month where recorded; different stations or rain-day definitions can affect comparisons.
No. Treat the capsule as a set of clothing functions: walking shoes, a base outfit, weather protection and any change for dinner or a venue's dress code. Start with equivalents you own. Adjust quantities to your trip length and laundry access; the illustrations are outfit suggestions, not a shopping requirement.
