Meteorological summer is less than a week away, but stable summer highs haven't quite elbowed their way into the skies over Germany yet.

“There will nevertheless be summery temperatures with highs of 25 to 28 degrees,” said Florian Engelmann from the German Weather Service (DWD).

But if you're spending time outside should also prepare for the possibility that sudden storms will break out.

On Saturday the first storm clouds will burst their seams over the south and west of the country in the early morning, DWD reports.

In the north and east the chances of bad weather will be smaller, but the weather will also be cooler, with highs between 19 and 23 degrees.

On Sunday the best chance for sun is in the east of the country.

The rest of Germany could be covered by thick clouds with the possibility of storms. But with temperatures still rising up to almost 30 degrees it promises to be pretty humid.

So it is mixed news for the open-air swimming pools, many of which have already opened their doors for the summer.

“I’ve been really happy with the season so far,” Mathias Nobel, the boss of the Heidebad open air pool in Halle, told Focus.

“The weather has been pretty changeable so far but, nevertheless, there’s been several warm and hot days.”

Last Sunday alone 500 people came for a dip at one of his three pools, as temperatures soared up to 30 degrees.

A spokesperson for the the open air pool in Arendsee, Saxony-Anhalt, was less positive.

While there have been warm days, “it takes a while before people change their mindset to summer bathing,” he said.
