Bangkok Weather in December
Planning a trip to Bangkok in December? Here's what the weather is really like as the city enters the cool and dry season — and why it might be the best month of the year to visit.
December in Bangkok is genuinely one of the top months of the year. Highs sit in the low to upper 80s°F, lows dip into the 60s (with averages in the mid-60s to low 70s), and humidity has dropped off dramatically compared to the brutal summer months. It's the driest month of the year with just 1–3 days of rain across the entire month, clear skies, and lots of sunshine. Compare that to August or September when half the month is filled with rain, and it's a huge improvement.
There are no meaningful weather alerts to worry about. The trade-off: December is one of the busier travel months, so expect higher hotel rates and pricier air travel as travelers take advantage of the ideal conditions. Meteorologist Ian Schwartz breaks down what to expect.

Genuinely one of the top months of the year. Highs sit in the low to upper 80s°F, lows dip into the 60s (averages in the mid-60s to low 70s), and humidity has dropped off dramatically compared to the summer months. It's the driest month with just 1–3 days of rain across the entire month, clear skies, and lots of sunshine.
Is December the best month to visit Bangkok?
Arguably. The weather is close to ideal — cool, dry, low humidity, essentially no weather alerts. Trade-off: it's one of the busier travel months, so expect higher hotel rates and pricier air travel. If budget matters more than perfect weather, February and November are close alternatives.
What should I pack for Bangkok in December?
Light, breathable clothing for the day (temperatures still hit the 80s°F), plus a light jacket or long sleeves for cooler evenings, mornings, and heavily air-conditioned indoor spaces. Sunscreen and sunglasses matter more than an umbrella — the rain risk is minimal.
