Summers are warm or even hot, with almost no cloud or rain for three months. The wettest season is winter, when the weather is generally mild at sea level although occasional spells of cold weather occur.

Spring and autumn are short seasons of transition from winter rain to summer heat and sun, when the weather may be very changeable from day to day. For those who dislike heat, April and May or September or October may be the most enjoyable seasons in Greece.

An outstanding feature of the Greek climate is the large amount of sunshine. This varies from four to five hours a day in midwinter to as much as twelve to fourteen hours a day in midsummer.
