With the weather in Thailand in December, comfort and cultural sensitivities should guide your choice of clothing. Choose lightweight, breathable cotton or linen clothing such as shorts, t-shirts and sundresses.
Also, don't forget swimwear for beach visits. In turn, when visiting temples and conservative neighbourhoods, don't forget to bring a headscarf, sarong or lightweight long-sleeved clothing for modesty and respect for local traditions.
Sunscreen is absolutely essential in December, so sunglasses, high-SPF sunscreen and a wide-brimmed hat are a must.
Also, although December is mostly dry, it's still worth bringing a light mackintosh or compact umbrella in case of rain, especially in the southern regions.
