Do I need a heavy rain jacket?

No. Bring a lightweight, breathable rain shell or poncho. In Thailand, it's often so hot that a heavy jacket will make you sweat more than the rain makes you wet.

Can I buy clothes there?

Easily. Market stalls everywhere sell cheap, loose-fitting cotton clothing that is actually better suited for the local climate than clothes you bring from home.

Packing for a Family Trip to Thailand: A Practical Guide

Focus on lightweight, breathable fabrics that cover your shoulders and knees for temple visits. Pack for humidity and unexpected rain by bringing quick-dry layers and one solid rain shell per person.

Select the right fabrics. Stick exclusively to linen, moisture-wicking synthetic blends, or thin cotton. Avoid denim or heavy knits, as they stay wet and heavy in the Thai humidity.
Solve the temple dress code. Carry a lightweight sarong or a pair of elephant pants in your day bag. Even if wearing shorts, you must cover your knees and shoulders to enter most sacred sites.
Plan for laundry. Don't pack for two weeks. Pack for five days and use local laundry services found on almost every street corner, which typically charge 40–60 THB per kilo for wash-and-fold.
Footwear strategy. Bring one pair of comfortable walking sandals (like Tevas or Chacos) and one pair of slip-on shoes. You will be taking your shoes off constantly to enter homes, shops, and temples.
