Weather in Poros in January
In Poros, January brings midwinter weather that is cool and fairly changeable. Daytime highs average around 13°C / 56°F, and nights drop to about 7°C / 44°F. There are typically 6 rainy days, with around 47 mm of rain in total. The sea averages about 16°C / 61°F, cold enough that only hardy swimmers go in. Poros is separated from the Peloponnese by a narrow channel, and its pine-covered hills make it greener than most Saronic islands. This is one of the drier corners of Greece, and bright, crisp days are common between rainy spells. You get about 10 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. Sunny spells between the rain can be beautiful, with clear air and long views. Make the most of the middle of the day, when it's warmest and brightest.
Swimming in Poros in January

Beaches are empty and unstaffed in winter, so swim only in calm conditions. If you do go in, a wetsuit is a good idea.
