October in Similan Islands brings a mix of warmth and rain. 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 nights, on the other hand, are pleasantly cool, making it a great time for evening strolls or late-night beach parties.
However, it’s not all sunshine and clear skies. The islands receive a significant amount of rainfall, about 200 mm, during this month. This means there will be frequent showers, sometimes heavy. The wind speed is also considerable, averaging around 16 km/h. So, while the temperature might be inviting, be prepared for sudden showers and breezy conditions.
