Can I wear shorts everywhere?

You can wear shorts in cities, on islands, and in bars, but you will be denied entry to temples and some government buildings if your knees are visible.

Is it better to pack light and buy clothes there?

Yes. You can buy cheap, lightweight clothes at any market in Bangkok. Don't overpack—you will likely end up buying local items that are better suited for the climate.

Do I need a heavy jacket for the North?

If you are visiting Chiang Mai or the mountains in December or January, pack one lightweight fleece or a hoodie. Nights can drop to 60°F (15°C).

Packing Clothes for Thailand’s Humidity and Heat

Prioritize loose-fitting, moisture-wicking natural fabrics like linen and lightweight cotton to survive the tropical heat. You need to dress modestly for temples, so always pack items that cover your shoulders and knees to avoid buying overpriced shawls on-site.

Choose your fabrics wisely. Avoid polyester and heavy cotton. Pack breathable, quick-dry synthetic blends or 100% linen. These fabrics allow airflow and dry in hours if you hand-wash them in your hotel sink.
Account for temple etiquette. Every temple requires shoulders and knees to be covered. Pack one pair of loose-fitting 'elephant pants' or lightweight trousers and a light linen shirt or scarf that can be thrown over a tank top.
Plan for sudden downpours. If traveling during the rainy season (June–October), pack a lightweight, packable rain poncho. Umbrellas are bulky and hard to carry; a thin poncho takes up no space and keeps your clothes dry during a tropical storm.
Use packing cubes for organization. Thailand is humid. Use mesh packing cubes to separate clean clothes from the inevitable pile of sweaty, dirty laundry to keep your entire bag smelling fresh.
