Greece Climate Guide to the Average Weather & Temperatures with Graphs Elucidating Sunshine and Rainfall Data & Information about Wind Speeds & Humidity:

The climate in Greece can be classified in three main types. An alpine mediterranean climate is found in the high mountains in the north of the country. Heavy snowfalls occur in bitter winters and summers are cool with regular thunderstorms. A continental, temperate mediterranean climate effects much of mainland Greece with greater daily and annual extremes of temperature than on the islands. Winters are cold with abundant frost and heavy snowfall especially on the high ground in the west. Summers are very hot with occasional thunderstorms.

This is typifed by dry, hot summers with abundant sunshine with warm nights and cool winters with lengthy spells of rainfall. The average annual Greece temperature has a range of 14 to 30 degrees celcius with record temperatures of -28 to +47.8 degrees.
