Greece's Mediterranean climate gives it long, hot, dry summers and mild, wet winters. Summer temperatures are tempered by breezes called 'Meltemia', and the Etesian wind which blows north across the Aegean Sea. Rainfall is generally low in most of the country and heaviest in the mountainous regions, where snow is likely and temperatures can get severe. Mercury on the mainland regularly hits the high spots.Summer (between June and August) is Greece's peak holiday season and draws millions of beach lovers to its gorgeous coastline. Autumn is pleasant for travellers who prefer smaller crowds and milder conditions, while winter (December to February) sees the coldest, most variable weather and is the least popular time to visit. Travellers looking to explore Greece's cultural and historical attractions should not be put off by the winter months.
