What's the weather like in Kefalonia?


Kefalonia is home to a glorious Mediterranean climate and like its neighbouring Ionian islands, the seasons each have distinct weather. The best time to come is summer, when temperatures are high, sunshine hours are at their peak and rain is almost non-existent. However this is also the time that most tourists arrive, so you may prefer to visit during the off-peak seasons for a quieter holiday and potentially better deals. Summer and early autumn are ideal for swimming in the sea, as it's at its warmest.

Winter weather in Kefalonia


Winter on this Greek island is usually mild but wet it is the significant rainfall during this period that keeps the island green and lush for the remainder of the year. The average temperature ranges between 9°C and 13°C and January is the coldest month of the year. The average seasonal highs are 12°C to 13°C and the average lows are between 5°C and 7°C.

Typically, 8 February is the coldest day of the year, with an average low of 8°C and high of 14°C certainly too cold for sunbathing, but fine for a brisk walk along the island's beautiful coastline, if you wrap up well.


December is slightly warmer than January and February, but also wetter and more overcast, as it's the cloudiest month of the year. Rainfall is high throughout the season, but decreases as it progresses. December experiences the year's highest rainfall at 115mm over 12 days. By February it is typically around half that at 55mm over 11 days. You can expect a 40% to 44% daily chance of rain during winter often thunderstorms or light to moderate rain showers. Winds are light, with only calm to moderate breezes. February usually experiences the strongest winds of the year.

Sunshine Hours

Sunshine hours are typically six to seven hours a day, while the sea temperature in winter is a chilly 15°C to 17°C.

Spring weather in Kefalonia


Spring in Kefalonia is a very pleasant time to visit, with slightly cooler temperatures than autumn but often sunnier and drier. Spring sees average temperatures of about 12°C to 18°C, ranging from lows of 6°C to 12°C to highs of 14°C to 22°C, rising as the season progresses. Springtime visitors can expect 8 to 12 hours of sunlight per day and very enjoyable conditions. The sea temperature rises from 15°C to 19°C over the course of the season.


Rainfall drops markedly over spring, with March expecting 45mm, decreasing to 30mm in April and again to just 20mm in May, over seven to ten days per month, so this is a good time to visit.

Sunshine Hours

Sunshine hours are on the rise, at eight to twelve hours per day on average. However, April brings the highest humidity of the year, usually being very humid three days out of four.


Wind speeds are still moderate breezes at most, with May experiencing the year's lightest breezes. This is also the time of year that the partly cloudy skies begin to clear.

Summer weather in Kefalonia

The hottest day of the year is typically 16 August, with an average high of 30°C and low of 23°C.


July is also the driest month of the year, often experiencing no rain at all, while June and August have just 5mm of rain over four or five days. The skies are often their clearest in July and this month is also the least humid of the year, with mildly humidity three days out of four.


While the island is in the path of the northeast Meltemi winds, these aren't as strong in the summer months so sometimes there isn't that cooling breeze to temper the scorching summer highs.
