Weather in Agathonisi in December

December in Agathonisi means early-winter conditions: cool and one of the wettest times of year. Temperatures typically peak at around 15°C / 59°F in the afternoon and fall to about 9°C / 48°F at night. Rain falls on around 10 days, with about 139 mm in total, usually in bursts rather than all-day drizzle. In the water, expect around 18°C / 64°F, refreshing for some, but too cool for most. Agathonisi is a small, rocky island close to the Turkish coast, exposed to the wind on most sides. Strong northerly and southerly winds are common, and the sea can stay rough for days at a time. You get about 9½ hours of daylight a day, so plan sightseeing for the middle of the day. Pack a warm jacket, layers and a waterproof, plus shoes that can handle wet paths. Plan outdoor time around the middle of the day, when it's at its warmest.

Swimming in Agathonisi in December

Swimming in Agathonisi in December is possible but bracing, with the sea at around 18°C / 65°F. Save swimming plans for July, August and September, when the water is much warmer. There are no lifeguards or beach services out of season, so swim with care. Quieter coves around the coast are often just as beautiful as the famous beaches. A short wetsuit helps if you feel the cold.

Crowds & Prices in Agathonisi in December

You'll have Agathonisi largely to yourself in December. Prices are at their lowest of the year, although fewer hotels are open. Christmas and New Year bring some Greek visitors home, but it stays quiet. Tavernas that stay open cater mainly to locals, which is often when the food is best. Book ahead anyway, as the few places that stay open are small.

What's Open in Agathonisi in December

In December, ferries between Samos and Patmos and Agathonisi run on a reduced winter timetable, and storms sometimes cause cancellations. Very little stays open: expect one or two tavernas and a few rooms at most. Archaeological sites and museums keep shorter winter hours. Most sites close on 25 and 26 December. Check opening days before setting out, as some places open only at weekends.

Festivals & Holidays in Agathonisi in December

On 6 December, Saint Nicholas, patron saint of sailors, is honored in harbors across Greece, and decorated boats appear alongside Christmas trees. Christmas is celebrated with church services, carols sung door to door by children and festive sweets like melomakarona and kourabiedes. Locals in Agathonisi mark these dates in the traditional way, and visitors are welcome to join in. Beyond that, it's a month of everyday life, with locals filling the cafés and tavernas in the evenings.

Is December a Good Time to Visit Agathonisi?

It depends on what you want. In December, Agathonisi is peaceful and inexpensive, but the season is over, the sea is too cool for most swimmers and the weather can turn. In numbers: highs of about 15°C / 59°F, lows of 9°C / 48°F and rain on around 10 days in a typical December. It's fine for a quiet break or exploring its quiet coves. For a proper beach holiday, go in June, September or October.

Start early, carry a warm layer and check the forecast. Paths link the island's three small villages with its quiet coves.

Do I need a car on Agathonisi in December?

No. Agathonisi is small enough to explore on foot, and the distances between the harbor, village and beaches are short. In December, seasonal minibuses and beach boats usually don't run, so be ready to walk and bring sturdy shoes.
