Weather in Kastoria

Planning a stroll through picturesque Kastoria? Check out the current weather conditions and detailed forecasts below to choose the perfect time to explore the city.

Kastoria, located in northern Greece, boasts a climate that differs significantly from the familiar heat of the southern islands. Here, a moderate continental climate with distinct seasons prevails. Thanks to its location in a mountainous area and its proximity to the lake, the weather is fresher here, giving the city a special charm and making it comfortable for sightseeing all year round.

Winter in Kastoria can be truly cool, with average temperatures ranging from 0°C to 3°C and regular night frosts. Summer, on the other hand, is warm and sunny, but usually without extreme heat: in July and August, the air warms up to a comfortable 28°C. This makes the city an excellent destination for those who want to enjoy warmth while avoiding exhausting heat.

Travellers should note that spring and the first half of summer can be quite humid: the number of rainy days reaches its peak in May and June. The driest and most stable period falls in the second half of summer and the beginning of autumn. September, for instance, delights with mild warmth and minimal rain, creating ideal conditions for long walks along the lake.

The temperature pattern in Kastoria is characterised by distinct seasonality, which is not always typical for the island part of Greece. The coldest period is winter, especially January, when average readings drop to 0.9°C. At this time of year, travellers should be prepared for night frosts: the thermometer often falls to -3.2°C, and during the day it rarely rises above 5°C. Such weather requires warm clothing but creates an incredibly cosy atmosphere for a winter holiday by the famous lake.

Summer here is mild and comfortable, without extreme heat. The peak warmth occurs in July and August, when daytime temperatures reach a pleasant 28°C. This is the ideal time for long walks, as the heat is easily tolerable. However, it is worth noting significant daily fluctuations: even in the hottest months, nights bring freshness, and the temperature drops to 16°C, so a light jacket or jumper will come in handy for evening strolls.

Transitional seasons are characterised by gradual temperature changes. Spring gathers strength by May, when the air warms up to 19-20°C, although nights remain cool (around 8-9°C). Autumn begins with a balmy September offering a comfortable 23°C during the day, but by November the approach of winter is felt, and the average temperature drops to 7°C. Such a climate makes Kastoria attractive for those seeking a variety of natural colours and wishing to avoid exhausting heat.

Precipitation in Kastoria is distributed throughout the year with interesting dynamics, creating a noticeable contrast between seasons. Winter months, especially December and January, are characterised by cold weather, when night temperatures often drop below freezing. During this period, there is a high probability of snowfall, which gives the city and Lake Orestiada a particularly picturesque look. On average, 8 to 12 days with precipitation per month are recorded in winter.

Spring and early summer can be unexpectedly wet here. May leads in terms of precipitation frequency: it can rain for up to 14 days a month. June also maintains this trend with approximately 13 rainy days. Travellers planning a trip at this time are strongly advised to carry an umbrella or raincoat, as spring showers are a fairly frequent phenomenon for this region of Greece.

The driest and most stable period arrives in the second half of summer and lasts until mid-autumn. From July to October, the number of inclement days is reduced to a minimum — averaging about 6 days per month. This time is considered the most favourable for long walks and sightseeing, as the sky most often remains clear, and precipitation, if it occurs, is usually short-lived.

When packing for Kastoria, it is important to remember that the climate here differs from the usual image of hot Greece, especially in the winter months. From December to February, the temperature often drops below freezing, so a warm jacket, scarf, hat, and gloves will become your best friends. For spring and autumn trips, the principle of layering is ideal: a combination of t-shirts, sweaters, and a light windbreaker will allow you to feel comfortable in changeable weather.

Summer in the region is mild and pleasant, with daytime temperatures around +28°C, so light clothing made from natural fabrics, sunglasses, and sunscreen will be very useful. However, keep in mind that frequent rains are possible in spring and early summer, so a compact umbrella or raincoat is worth putting in your luggage. And, of course, for long walks along the colourful streets and the lake embankment, be sure to bring comfortable, proven footwear.
