This shift in weather patterns sets the stage for the start of the Mediterranean tourist season in Greece, with many popular destinations welcoming visitors during this time.
One of the most notable features of the Greek climate in September and October is the regional variations in temperature and precipitation. The northern regions experience cooler temperatures and more rainfall compared to the southern regions, which remain relatively warm and dry.

September Weather Patterns in Greece

September marks the beginning of autumn in Greece, with warm and pleasant weather prevailing across the country. As the summer heat slowly dissipates, the weather in September becomes more moderate, with temperatures gradually decreasing. The Mediterranean climate of Greece, characterized by mild winters and hot, dry summers, starts to exhibit a more pronounced autumnal trend in September.
Typically, September in Greece is dominated by high-pressure systems, which bring clear skies and warm temperatures. These systems are often associated with the Azores-Benguela high-pressure belt, a large-scale circulation pattern that influences the weather in the eastern Mediterranean. As a result, September tends to be a dry month in Greece, with most areas receiving less than 30 mm (1.2 in) of rainfall.
High-Pressure Systems and Their Effects
The domination of high-pressure systems in September leads to several key effects on the Greek climate. Firstly, the clear skies and light winds allow temperatures to remain high during the day, with average highs ranging from 25°C (77°F) in northern Greece to 28°C (82°F) in the southern regions. Secondly, the dry air associated with high-pressure systems results in low humidity, making the weather feel more pleasant for tourists and residents alike. Finally, the stable atmospheric conditions conducive to high-pressure systems also lead to fewer thunderstorms and other severe weather events, making September a generally safe and pleasant time to visit Greece.
Setting the Stage for the Tourist Season
September weather sets the stage for the start of the Mediterranean tourist season in Greece, which typically runs from June to October.
