The climate of Skiathos can be described as classic Mediterranean, ensuring comfortable conditions for a holiday during most of the year. This Greek island is characterized by distinct seasonal changes: here you can expect a hot, dry summer, perfect for a beach holiday, and a mild but rather wet winter, when nature takes a break from the heat.

The summer months, especially July and August, are distinguished by stable sunny weather. The average air temperature during this period is around 25–26°C, and rainfall is extremely rare — just 2–3 days per month. This is the most popular time for tourists wishing to enjoy the warm sea. In winter, from December to February, it gets cooler (averaging about 10–12°C), and the number of rainy days increases to 11–12 per month.

The transitional periods — spring and early autumn — deserve special attention. May and September offer a pleasant balance: the air warms up to 18–23°C, rains are not yet frequent or are already receding, and sweltering heat is absent. This time is perfect for those who want to combine walks around the island with a comfortable stay in the fresh air without extreme temperatures.

The climate of Skiathos is distinguished by its mildness and comfortable conditions, typical of the Greek islands. The hottest period falls at the end of summer: peak temperatures are observed in August, when average figures reach 25.9°C, and daily highs hold at around 27.4°C. July is practically just as warm, with an average temperature of 25.5°C. Summer here can be described as pleasantly warm, ideal for a beach holiday, but without exhausting extreme heat, making a stay on the island comfortable for most tourists.

Winter months on the island pass quite mildly, without severe frosts. The coldest month of the year is January, when the average temperature drops to 9.9°C, and nightly lows are around 8.3°C. February and December are only slightly warmer, keeping figures in the 10–12°C range. Such weather feels cool but not harsh, allowing for walks and sightseeing if you take care to wear suitable clothing.

A characteristic feature of the temperature regime on Skiathos is its surprising stability throughout the day. According to statistics, the difference between average night (minimum) and day (maximum) temperatures is minimal and often does not exceed 2–3 degrees. This means there are no sharp drops: nights remain warm in summer and moderately cool in winter. Transitional periods, such as May and September, offer the most balanced conditions with average temperatures from 18°C to 23°C, which many travellers find to be the "golden mean".

The climate on Skiathos is characterized by a distinct division into a dry summer season and a wetter winter period. Since even in the coldest months the temperature rarely drops to critical levels, precipitation here falls primarily in the form of rain. Snow on the island is an extremely rare phenomenon and uncharacteristic for this region of Greece.

The driest period, which is most favourable for a beach holiday, lasts from June to August. During these months, the probability of precipitation is minimal: for example, in July and August, only 2–3 rainy days are recorded. Summer rains, if they occur, are usually short-lived and are quickly replaced by bright sunshine.

The wet season begins in November and continues until March. The rainiest months are considered to be January and December, when the number of days with precipitation reaches 12 per month. During this period, the weather becomes more changeable, so travellers planning a trip in winter should definitely take an umbrella or raincoat with them.

The transitional seasons — spring and early autumn — offer a moderate amount of precipitation. In April and September, the number of rainy days is about 7 per month. This time is perfect for those who prefer mild weather without the summer heat, but with a lower risk of prolonged rains than in winter.

When packing for Skiathos at the height of the summer season (from June to August), opt for light clothing made from natural fabrics such as cotton and linen to feel comfortable at an average temperature of about 26°C. Since rains are extremely rare here in summer, the basis of your wardrobe will be beachwear, shorts, and T-shirts. Be sure to take care of reliable sun protection: a hat, high-quality sunglasses, and cream with high SPF are your main companions on the Greek islands.

If you are planning a trip in the off-season or winter, when the thermometer drops to 10–12°C, the approach to packing should be different. During this period, the number of rainy days increases (up to 11–12 days per month), so a waterproof windbreaker, raincoat, or sturdy umbrella will become indispensable items. Use the layering principle: a combination of a T-shirt, a warm jumper, and a light jacket will allow you to quickly adapt to weather changes and the sea breeze.

Regardless of the time of year, put comfortable shoes with flat soles or trainers in your suitcase. Skiathos encourages long walks along the cobbled streets of the old town and nature trails, where heels would be completely inappropriate. Also, a light scarf or shawl, which will protect you from the wind during evening walks by the sea or boat excursions, will not go amiss.
