Weather and climate

Temperature: 9-30°C 

Summer is the best time to explore the island’s stunning beaches. Temperatures regularly hit 30°C in July and August, when the sea is also at its warmest. It’s also worth bearing in mind that this is the busiest time of year. As we move through the autumn, the island starts to cool down slightly (and the crowds start to disappear), but the sea is still warm enough to swim in throughout October. Kefalonia’s lush, green scenery is all thanks to significant rainfall in winter, but temperatures very rarely drop below 9°C during this season. If you’re keen on hiking or caving, it’s a good idea to book your holiday for spring; you’ll be spoilt with a dry, mild climate and an average of eight hours of sunshine a day.

Getting around

By car: It’s the way to explore the island’s 237km-long coastline, so why not pick up a hire car at the airport? That way you’ll have the freedom to explore at your own pace.  

By motor-cruiser: Head out to sea on one of these small motor boats; they’ll get you around to some of the island’s secret spots and untouched beaches.

By boat: From Vatsa Bay on the southern tip, you can take a traditional fishing trip to see what you can catch; or book a daily boat safari from Lixouri harbour.


15 August: Did you know that 15 August is Greece’s biggest religious holiday? Kefalonians gather in tavernas and squares across the island to eat, drink and dance. Head to Markopoulo to see the ‘sacred’ baby snakes that appear around the village church every year.

Wine Festival: Pencil in the third weekend of August to celebrate the island’s famous Robola wine. It gets its own festival, which is held in the village of Fragata, and attracts thousands of visitors every year. How does free Robola, local delicacies and live music sound? 

International Music Festival: Head to the island capital of Argostoli for the International Music Festival, held across many music venues at the end of August.
