The climate in Greece differs somewhat between regions. The northern parts of the mainland have colder winters and hot, humid summers. On the other hand, the southern parts of the mainland and the islands to the southeast have a more typically Mediterranean climate with milder winters and hot, dry summers. Generally though, it can be said that Greece has warm summers and mild winters.
Broadly speaking, snow in Greece becomes less common the further south and the closer to sea level one goes. Some of the higher mountainous areas can have alpine climates with heavy winter snowfall. It does occasionally snow in and around Athens, however.
The hottest months of the year are July and August, where temperatures can reach 104°F (40°C). Rain starts from the middle of October and can continue through February, punctuated by days with a mild winter sun and clear skies.
