Greece’s weather in August is proving to be as unpredictable as ever, with alternating spells of sunshine, rain, hail, and powerful seasonal winds known as meltemia.

On Thursday, much of mainland Greece will experience unsettled weather, with local showers and thunderstorms expected, particularly during the afternoon hours

According to the National Meteorological Service (EMY), today's temperatures will fall by 2 to 3 degrees Celsius, and by Sunday, June 29, the mercury is not expected to exceed 32 to 34°C across most areas.

Apart from the direct hazards of thunderstorms and high winds, experts warn that the extremely low surface humidity may significantly elevate the risk of fires being sparked during storm activity.
