December in Bangkok offers a delightful escape from winter woes, as the city transitions into its "cool" season. While still warm and tropical, this month brings a welcome reprieve from the intense heat and humidity, making it an ideal time to explore the bustling streets and vibrant culture.
We'll tune the list to your exact trip — dates, activities, and weather.
December in Bangkok sees average highs around 88°F (31°C) and lows dipping to a comfortable 72°F (22°C). This is considered one of the most pleasant times to visit, with significantly lower humidity compared to other months. Rain is highly unlikely, with only about 1.2 inches (30 mm) of rainfall spread across an average of two rainy days. You can expect around 11 hours of daylight, offering ample time for sightseeing.
Lightweight, breathable clothing is key for Bangkok, even in December. Think cottons, linens, and quick-drying fabrics. While the weather is more forgiving, modest dress is still important, especially when visiting temples and religious sites. Shoulders and knees should be covered, so pack scarves or sarongs for easy layering.
