What's the weather like in Kefalonia in August


August, along with July, is the hottest month of the year on the naturally beautiful Ionian island of Kefalonia. It is also the busiest as it is peak tourist season. The international visitors include many people from nearby Italy, joined by those from other parts of Greece, who head to the islands for their summer vacations.

Boasting average temperatures of 26°C, it's not unusual for daytime temperatures to soar to 29°C. Overnight temperatures drop to an average low of 18°C, so t-shirts, shorts and sandals can be worn throughout the day and into the evening.

High Temperatures

This Greek island has reached a sweltering record daytime high of 38°C in August, so be sure to bring your sun screen and protective clothing if you are sensitive to the heat. It's best to book accommodation with air-conditioning to avoid feeling uncomfortably hot indoors. The lowest August temperature on record is 16°C. Temperatures tend to stay constant through most of the month, dropping a degree or two over the last week.


August is the last month of the summer dry season, with just 5mm of rain over four days. The skies are mostly clear, becoming cloudier as the month progresses. The seasonal meltemi winds traveling in from the Aegean Sea take the edge off the heat, occurring mostly in the afternoons and evenings, but sometimes continuing over a few days. Generally you can expect to experience calm to moderate breezes and wind speeds gradually tail off as the month progresses. Do take care to use plenty of high SPF sunscreen at this time of year and try to avoid being in the sun during the hottest parts of the day. Although the meltemi winds may make things feel slightly cooler, the sun's rays are still extremely powerful. You can check the local weather forecast to find out when the day will be warmest and plan your day accordingly.

Sunshine Hours

The number of sunshine hours dips slightly to a still bright thirteen hours a day, while the sea temperature warms up yet another degree to 26°C its warmest temperature of the year. This means you can spend long, warm, sunny days at the beach, taking a refreshing dip in the sea to cool off or get adventurous with some high octane water sports.
