Mediterranean climate

The climate of Greece is similar to that of other Mediterranean regions. In the lowlands the summers are hot and dry, with clear, cloudless skies. The winters are relatively mild, but rainy. The mountainous regions are much cooler, with considerable rain during the summer months. Frost, sleet, ice, or snow are rare in the lowlands, but most mountains are covered with snow in the winter.

Precipitation varies from region to region. For example, in Thessaly less than 38mm (1.5in) of rain falls in some years, whereas parts of the western coast receive about 1,270mm (50in). The mean annual temperature in Athens is about 17° C (63° F); the extremes range from a normal low of -0.6° C (31° F) in January to a normal high of 37.2° C (99° F) in July and at times higher in August.
