Skiathos enjoys a classic Mediterranean climate with hot, dry summers and mild, wet winters; the best time for a beach holiday is June to September, when sea temperatures are warm and rainfall is minimal.
What is the weather like in Skiathos by month?
Summer (June–September) brings daily highs of 28–32°C, almost no rain, and a steady meltemi breeze that moderates the heat. Spring (April–May) and autumn (October) are pleasant for walking and sightseeing, with temperatures from 18–25°C and fewer crowds. Winters are mild, averaging 10–15°C, but expect rain and some windy days. For reliable sun, aim for June or September; July and August are hottest and busiest with school holidays.
What should I pack for Skiathos?
For summer, pack light cotton clothing, swimwear, a sunhat, high-factor sunscreen, and a light jacket or wrap for cooler evenings. The meltemi wind can pick up, so a windproof layer is useful for boat trips. In spring and autumn, add a waterproof jacket and a few long-sleeved tops. Comfortable walking shoes are essential if you plan to explore the island’s trails or the old town.
Is Skiathos windy in summer?
Yes, the meltemi wind often blows from the north in July and August, which can make beaches on the north coast choppy. The south coast beaches, such as Koukounaries, are usually calmer and more sheltered.
When is the rainy season in Skiathos?
Rain is most likely from November to February, with December the wettest month. Even then, showers are often short and followed by sunshine. Summer months see very little rainfall — typically less than 15mm per month.
What is the skiathos weather 14 days forecast like?
As with any Mediterranean destination, the 14-day outlook is reliable for general trends but less accurate for specific days. For a better idea, check the live forecast above or the 10 Day Weather Forecast UK for comparison.
