The weather in Athens can only be described as heavenly. Mild winters, low humidity, hot summers and pleasant autumns.
During the spring and summer, Athens is very hot and dry. There are subtropical pressure systems that create a Mediterranean subtropical climate. During the summer, the dry heat and excessive smog can make it very uncomfortable to be outside. Autumn and winter can be changeable due to a polar front exerting its influence over the region. It is often mild but very rainy. Summer temperatures tend to reach around 31 degrees Celsius, and winter tends to stay around the 16 degrees Celsius mark, falling as low as 5 degrees Celsius. Occasionally, winter will produce a snowstorm that paralyses Athens for a while.
There are almost 3000 hours of sunshine per year.
Rainfall is sparse and is enjoyed from mid October to mid April. Sometimes, a few showers are observed in the summer months. Because of low rainfall long periods of drought are no acception. Drought is a problem Greece has to cope with, as the risk of forest fires are high in this season. Athens also experience snowfalls almost every year.
Dry and wet:
Dry and wet conditions occur in the Aegean islands. During the summer the conditions are most frequently dry and sunny, and any rain that falls is in the form of showers, or thunder storms. The air is usually hot during the day and warm during the nights, but on the Cyclades islands, and surrounding area, there will be some windy days. Heat waves do occur but mostly on coastal areas and are usually around 40°. There are a few areas that are affected by heat waves in the area. A heat wave is where high temperatures persist into the night. For this reason most residents tend to spend the summers on one of the islands where the heat is tempered by a sea breeze.
