Along with being one of the coldest months of the year, with an average temperature of 10°C (50°F), January has very little sunshine and a fairly high chance of rain for Athens standards. Winter is truly at its peak in January; however, for those that live in the city life goes on as normal.
The main difference is that some tourist attractions are closed, and there are generally fewer people hitting the streets.
If the cold weather on land is not enough of a deterrent, then the temperature of the water is. At a chilly 16°C (60.8°F), even the bravest swimmers are likely not to desire to venture into the water. Winter months are better for hiking and exploring then enjoying the beach.
