December in Southern Thailand is a mix of warmth and wet showers. The temperature usually swings between a comfortable 24°C at its lowest and a slightly hot 30°C at its peak. This makes it a pleasant time for those who enjoy a balance of cool and warm weather. The wind speed is moderate, blowing at around 8 km/h, adding a gentle breeze to the overall climate.
Rainfall is quite significant in this month, with about 70 mm of rain expected. This means there will be frequent showers throughout the month. Despite the rain, the sun does make its appearance, although not as much as in the drier months. So, while you can expect some sunny spells, be prepared for sudden showers as well.
