Temperatures are set to drop on average by 12 degrees Celsius on Wednesday and strong northerly winds of up to 9 Beaufort may create problems in ferry routes between mainland Greece and the Aegean islands.
According to the weather forecasts the midday temperature in Athens will drop from 34°C on Monday to 26°C on Tuesday and 22°C on Wednesday.
The same weather pattern is forecast for Thessaloniki, Greece’s second largest city where on Wednesday midday temperature will not exceed 22°C.
