Aegina weather by month: heat, sea temperature and rain
A monthly table for the Saronic islands, what to expect each season, and when the sea is warm enough to swim.
- June to September: hot and dry, sea 21–24°C.
- October is still good for swimming; November to January are the wettest months.
- Aegina is close to Athens, so its weather is very similar to the city's.
If you are in Athens and want a day on an island, Aegina works all year. Go from June to October to swim; in winter plan a day of sightseeing and food rather than beaches.
Aegina weather: what to expect
Aegina is a Saronic Gulf island about an hour to an hour and a half by boat from Piraeus. Its weather is close to Athens: hot, dry summers and mild, rainy winters. In summer a northerly wind sometimes takes the edge off the heat, and winter mixes grey, rainy days with clear, pleasant ones.
Aegina weather by month
Climates to Travel has no station on Aegina itself. The table uses the Hydra station, which the site presents as representative of the Saronic islands (long-term averages, rounded). Aegina, closer to the mainland, differs only slightly.
