North and Central Thailand (Bangkok, Chiang Mai): cool and dry — excellent sightseeing weather. Southwest coast (Phuket, Krabi, Koh Lanta): prime dry season, calm Andaman seas. Gulf coast (Koh Samui): transitional — some early December rain possible, clearing toward month end. East coast (Koh Chang): can be wet in early December.

Phuket and Krabi in December are at their best — prioritise these if beach weather is the goal.
Bangkok in December is comfortable and festive — ideal for a city start or end to a trip.
Avoid Koh Samui in early December if beaches are the priority — the Gulf coast's northeast monsoon lingers.
December flights to Thailand are significantly more expensive — consider arriving in November or mid-January for similar weather at lower costs.
