Weather in Kefalonia in January
January is the heart of winter in Kefalonia: cool and often wet. Daytime highs average around 14°C / 58°F, and nights drop to about 8°C / 47°F. Rain falls on around 9 days, with about 103 mm in total, usually in bursts rather than all-day drizzle. Sea temperatures average around 16°C / 61°F, too cold for most people to swim. The winter rain is what keeps this coast so green, and storms can roll in quickly from the west. Kefalonia is the largest Ionian island, dominated by Mount Ainos, which can see snow in winter. Daylight lasts about 10 hours, so plan sightseeing for the middle of the day. Pack a warm jacket, layers and a waterproof, plus shoes that can handle wet paths. Short days and changeable skies are part of the appeal, with fewer visitors and a more local feel. Make the most of the middle of the day, when it's warmest and brightest.
Swimming in Kefalonia in January
The sea around Kefalonia averages about 16°C / 61°F in January, which is cold for swimming, though a few hardy locals still take a dip. The best time for swimming is July, August and September, with August usually the warmest. Beaches like Myrtos and Antisamos are still worth a visit for the scenery and a walk along the shore. There are no lifeguards or beach services out of season, so swim with care. A wetsuit makes a big difference if you want to get in.

Festivals & Holidays in Kefalonia in January
New Year's Day is a public holiday, celebrated with family meals and vasilopita, a cake with a lucky coin baked inside. On 6 January, Epiphany, priests bless the waters, and young swimmers dive in to retrieve a cross thrown into the sea. In Kefalonia, these occasions are celebrated much as they are across the rest of Greece. Otherwise, life follows its normal rhythm, with Sunday lunches and busy cafés rather than big events.

Frequently Asked Questions
What time does the sun set in Kefalonia in January?
Through January, sunset in Kefalonia moves from around 5:30 pm to around 6:00 pm in Greek local time, as the evenings get longer. In mid-January, expect it at around 5:40 pm. With short days, plan outdoor sightseeing for the morning and early afternoon.
Does it rain a lot in Kefalonia in January?
Yes. Western Greece is the wettest part of the country, and January is one of its rainiest months. Rain often comes in heavy bursts with passing storms, separated by clear, mild days. That rain is what keeps the landscape so green, so pack waterproofs and enjoy the quiet.
Can I visit Melissani Cave in January?
Possibly not. Show caves in Greece often keep reduced hours or close for part of the off-season, so check before you go in January. When it is open, the temperature inside stays much the same all year. Its underground lake is explored by rowing boat and is at its most magical when sunlight pours through the open roof around midday.
Do I need a car on Kefalonia in January?
Yes, if you want to see more than Argostoli. Bus services are limited in January, and a car makes it easy to reach villages, beaches and viewpoints. Rental rates are among the lowest of the year, but fewer agencies are open.
Is January or February better for visiting Kefalonia?
There's little between them. Both are the heart of the off-season, with cool, changeable weather and a quiet, local feel. February brings slightly longer days, the first almond blossom and often the start of carnival season, while January has Epiphany on 6 January. Choose by your dates, and keep ferry plans flexible.
