Water temperatures in the Mediterranean are at a high for this time of year, great for holidaymakers during the school break, but bad news for the coming months.

Over the next few months, the weather in the Mediterranean will become more volatile and, above all, more thundery. While temperatures in the sea will start to cool from mid-September, cooler air and troughs arriving from autumn will lead to increased instability.

The warmer the Mediterranean, the more powerful the thunderstorms will be. Consequently, the likelihood of storms with heavy rain, hail, and squalls also increases.

Last week's images from the Balearic Islands may already have been a foretaste of the autumn months ahead.

On Menorca, 150 litres of rain per square metre fell within three hours. Roads turned into raging rivers.

While the warm waters are great for those visiting during the school holidays, they could spell trouble for locals in autumn.
