What’s the weather like in Thassos in September?

Located off the coast of Greece in the Aegean Sea, Thassos is a beautiful island and popular holiday destination. It has a Mediterranean climate which brings hot, dry summers and cool, damp winters to the region. In September, Thassos is still warm and sunny after the summer months, so this is a good time of year to visit for relaxing on the beach or exploring the island, while avoiding the high season crowds.


The average temperature in Thassos at this time of year is 19°C, with highs of 24°C in the peak of the afternoon. Although it can get quite warm in the daytime, you’ll need to pack a few jumpers and a jacket for evenings out as temperatures drop to a low of 14°C. Around 35mm of rain’s expected during September, but with just seven days affected by rain showers it’s unlikely the wet weather will ruin your holiday. If you want to swim in the sea, the Aegean waters are a warm 23°C this month.
