Weather in Kithnos in January
January is the heart of winter in Kithnos: cool and often wet. Expect highs of about 14°C / 56°F and overnight lows near 9°C / 47°F. The sea averages about 16°C / 61°F, cold enough that only hardy swimmers go in. Expect rain on around 8 days and about 73 mm over the month, often in heavy bursts with dry spells between them. Kythnos is a low, quiet island in the western Cyclades, within easy reach of Athens. Winter here is shaped by the wind: storms sweep through regularly, often followed by calm, bright days. Daylight lasts about 10 hours, so plan sightseeing for the middle of the day. Bring a warm coat, layers, an umbrella and shoes that can cope with rain. Short days and changeable skies are part of the appeal, with fewer visitors and a more local feel. Plan outdoor time around the middle of the day, when it's at its warmest.
Swimming in Kithnos in January
Swimming isn't really on the cards in Kithnos in January, with the water at around 16°C / 60°F. For warm-water swimming, aim for July, August and September, when the sea is at its best. Beaches such as Kolona are lovely for a walk, even when the water is too cold to swim. There are no lifeguards or beach services out of season, so swim with care. If you do go in, a wetsuit is a good idea.
Crowds & Prices in Kithnos in January
You'll have Kithnos largely to yourself in January. It's the cheapest time to visit, with the best deals on accommodation. Go midweek if you can, as weekends bring visitors from Athens. With so few visitors, the atmosphere is genuinely local, and people have time to chat. Tavernas that stay open cater mainly to locals, which is often when the food is best. You can usually book at short notice.
What's Open in Kithnos in January
In January, ferries between Piraeus and Lavrio and Kithnos run on a reduced winter timetable, and storms sometimes cause cancellations. Most hotels, restaurants and bars close for the winter, and only a few places stay open for locals. Museums and archaeological sites are open on winter hours. Most sites close on 1 January. Check opening days before setting out, as some places open only at weekends.
Festivals & Holidays in Kithnos 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 Kithnos, 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.
Is January a Good Time to Visit Kithnos?
January is worth it for Kithnos if you're interested in culture, food and walking rather than beaches. In numbers: highs of about 14°C / 56°F, lows of 9°C / 47°F and rain on around 8 days in a typical January. It's quiet, prices are low and the main town still has plenty going on, but the sea is cold and many resort businesses are closed. For beach weather, come in June, September or October instead.
Frequently Asked Questions
What time does the sun set in Kithnos in January?
Through January, sunset in Kithnos moves from around 5:15 pm to around 5:45 pm in Greek local time, as the evenings get longer. In mid-January, expect it at around 5:25 pm. With short days, plan outdoor sightseeing for the morning and early afternoon.
Is the sea rough in Kithnos in January?
It can be. January is one of the stormiest months in the Aegean, and strong northerly or southerly winds regularly whip up rough seas. On the worst days, ferries and small boats are delayed or cancelled, so leave a spare day before any flight home. Calm, sunny spells between storms are common too.
Can I visit Kolona beach in January?
Yes, you can reach Kolona beach all year, and in January you'll probably have it to yourself. Don't expect sunbeds, beach bars or lifeguards, and the sea is cold for swimming, but it's a beautiful place for a walk on a calm, sunny day. The sandbar links Kythnos to the islet of Agios Loukas.
Do I need a car on Kithnos in January?
Yes, if you want to see more than the port. 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 Kithnos?
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.
