Greece : climate and when to go to Athens
Temperate climate, mild, wet winters, hot and dry summers. The climate in Greece is typical of the Mediterranean climate: mild and rainy winter, relatively warm and dry summer, and generally prolonged periods of sunshine for most of the year. A wide variety of climate sub-types, also in the Mediterranean climate approach, is present in several regions of Greece. This is due to the influence of topography (large mountain chains, along the central part), and to the air masses coming from the moisture sources of the central Mediterranean Sea.

Weather uncertainties 2025 to go to Athens ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Athens for a good trip to the sun!
