Lightweight cotton and linen fabrics breathe well in humid conditions. Pack a mix of casual and smart-casual clothing; while Thailand is generally informal, upscale restaurants and bars in Bangkok may enforce dress codes.
For temple visits, cover your shoulders and knees. Carry a lightweight scarf or sarong that can double as a cover-up. Remove shoes before entering temple buildings; slip-on footwear is convenient.
Sun protection is essential: pack high-SPF sunscreen, a wide-brimmed hat, and quality sunglasses. Mosquito repellent with DEET is important, particularly for evenings and jungle or island destinations.
A small daypack is useful for excursions. Include a reusable water bottle, as staying hydrated is crucial in the heat. A lightweight rain jacket or compact umbrella handles sudden tropical showers.
