Don’t throw away your umbrellas and rain gear just yet. While pleasant temperatures have been keeping much of Germany in a summer state of mind the past few weeks, this is expected to change starting Wednesday evening.

Just in time for Thursday’s celebrations of both Father's Day and Ascension Day, the German Weather Service (DWD) is calling for heavy rain, winds and hail across the country.

To begin the national holiday of Himmelfahrt, scattered thunderstorms are expected to sweep across the country from the west, starting in the late hours of Wednesday evening.

People living in states like North Rhine-Westphalia and Baden-Württemberg can expect thunderstorms early in the day on Thursday, as well as slightly cooler temperatures reaching a high of between 15C and 23C, according to the DWD.

Eastern Germany will enjoy sun and temperatures reaching as high as 28C during the daytime hours, with a light breeze.

However, by nightfall, eastern residents can expect “high storm potential”, said DWD, with heavy thunderstorms and even hail in the forecast.

In areas such as Berlin and Hamburg, up to three centimetres of hail is expected.

Despite the turbulent weather on Thursday, temperatures are predicted to rise back into the mid-20s again by Friday, with dry and sunny conditions expected in most areas throughout the weekend.

What temperatures can we expect in Germany this week?

Parts of Germany will see another heatwave this week as temperatures soar.

What temperatures can we expect in Germany this week?

The German Weather Service (DWD) has predicted that the mercury will climb in some regions of to around 34C this week. 

“After low pressure ‘Karin’ gave parts of Germany rain, sometimes in large quantities, high pressure ‘Piet’ is now back in pole position,” said meteorologist Lars Kirchhübel of the DWD.

This high pressure zone will dominate the weather in large parts of western and central Europe over the coming days, the weather expert said, adding that it will reach Germany too. 

On Monday temperatures remained fairly cool across the country after a weekend of showers, but they are set to climb over the course of the week, particularly on Wednesday and Thursday. Forecasters predict it could reach 32C in Stuttgart and 33C in Cologne on Thursday. Locally, temperatures could reach 34C. 

However, from the Oder and Neisse rivers to the Erzgebirge mountains and southeast Bavaria, denser clouds and some showers are to be expected. This is due to a high-level low pressure system over the Balkan region, according to forecasters. Short showers are also possible in the Black Forest.

“In most of the rest of the country, high ‘Piet’ will be able to hold its ground,” said Kirchhübel.

At the end of the week, thunderstorms are forecast but temperatures are expected to remain high. 

August in Germany ‘too dry’

According to the European Centre for Medium-Range Weather Forecasts, August as a whole – apart from a few areas in eastern Germany – will be too dry compared to the multi-year average.

The Black Forest, the High Rhine and the Allgäu to the Bavarian Forest, however, are not expected to have any major problems due to the high rainfall of the past few days.

“Looking at Rhineland-Palatinate, the southern half of Hesse, the western half of North Rhine-Westphalia and Lower Franconia shows a different picture,” said Kirchhübel. In the last 30 days, only about 10 percent of the usual level of precipitation fell in some places.

“At some stations, no precipitation at all has been measured in August,” added Kirchhübel, referencing Würzburg as an example.

Rainfall at the weekend caused the water in the Rhine river to rise slightly. In Emmerich, the water level reached a positive value again after the historic low of the past few days: in the morning, it showed three centimetres – an increase of six centimetres compared to the previous day.

The water level also rose by several centimetres at the other measuring points in North Rhine-Westphalia: in Cologne, the level rose to 80cm and in Düsseldorf to 38cm.

Despite this encouraging trend, the Waterways and Shipping Authority said it did not expect a huge improvement in water levels in the foreseeable future due to more hot weather coming.
