Greece has a warm Mediterranean climate. In summer, dry hot days are often relieved by stiff breezes, especially in the north and coastal areas. Athens can be stiflingly hot, so visitors should allow time to acclimatise. The evenings are cool. Winters are mild in the south but much colder in the north. November to March is the rainy season.

Lightweight clothes during summer months, including protection from the midday sun. Light sweaters are needed for evenings. Waterproofs are advised for autumn. Winter months can be quite cold, especially in the northern mainland, so normal winter wear will be required.
