Weather: Rain, storms and temperature drop from Wednesday

The deterioration will begin in northern areas and gradually spread to central and southern Greece, creating a brief autumn-like pattern. Weather activity is expected to intensify during the afternoon and evening hours, with locally strong storms, possible hail and frequent lightning.

Meteorologists say the unstable conditions will continue into Thursday, affecting central and southern mainland regions as well as parts of the Aegean, before gradually improving from Friday onward starting in the north.

According to forecasts, the system is driven by colder air masses moving in from the Balkans, leading to increased instability and a temperature drop of several degrees. Maximum temperatures will fall to around 18–22°C in many areas, while stronger winds from the north will further reinforce the cooler feel.

In Athens, conditions will remain relatively mild on Tuesday but will turn more unsettled from Wednesday and Thursday with a higher chance of rain. Thessaloniki is expected to see rain and storms earlier, with improving conditions later in the week.

Overall, the weather will take on a more autumn-like character midweek, before gradually stabilizing and warming again toward the weekend.
