September in Krabi is a mix of warm and wet. The temperature swings between a comfortable 25°C at its lowest and a slightly hot 31°C at its peak. This means you can expect the days to be warm, but not unbearably so. The heat is tempered by the wind, which blows at a moderate speed of 15 km/h, bringing a refreshing breeze.
However, it’s also a rainy month with rainfall reaching up to 220 mm. This means there will be quite a few showers throughout the month. Despite the rain, the sun does make an appearance, although not as much as in the drier months. So, while you can enjoy the warmth, be prepared for sudden showers.
