Weather on Iraklia is the typical weather of all Cyclades islands, with sunny summers and windy winters. Summer is certainly the best period to visit Iraklia and all Greek islands. The sun is shining about 15 hours a day and while some days can be really hot, reaching 40 degrees, a light breeze usually blows in the afternoon and makes the atmosphere chillier. In winter, winds blow very strong and temperatures fall, but usually not under 5°C. A few showers occur in autumn and spring and temperatures are kept at moderate levels.
