The first signs of spring weather begin to appear. March is a great time to visit Athens before the temperatures begin to get too high. The average temperature is 12°C (53.6°F), so although a coat is likely to be needed, the winter chill starts to ease slightly.
There is generally a mix of cloudy and sunny days, and being the third rainiest month, a little rain from time to time is expected. Towards the middle of the month, the number of sunny days rises, making the days in Athens feel a bit warmer.
Although spring seems to be appearing in March, the rise in temperature is not yet detected in the waters, with an average sea temperature is 15°C (59°F), the coldest it gets during the year. Very few people are comfortable to go for a swim.
