Humidity and Comfort Considerations
Bangkok stays humid for most of the year. The stickiest days hit during the rainy season (May to October), making the air feel hotter than the thermometer says. If you’re coming then, prepare for some sweaty afternoons.

I’d say keep water handy and duck into air-conditioned places when you need a break. Lightweight, breathable clothes make a difference when it’s muggy.
What to Pack for Each Season
For the cooler, drier months (November to February), I pack light layers for mornings and evenings—sometimes you’ll want a jacket or sweater.
When it’s hot (March to May), I reach for loose, light-colored clothes made from cotton or linen. Sun hats and sunscreen are non-negotiable for me.
During the rainy season (June to October), I never forget a waterproof jacket or poncho, plus shoes or sandals that can handle puddles. Quick-dry clothes save the day when you get caught in a downpour.
Packing checklist by season:

|---|---|
| Cool & Dry | Light jacket, long pants, layers |
