Examine these graphs indicating the current severe rainfall deficiency.
In an unprecedented drought that's part of a broader European crisis, Germany has barely seen a drop since winter. Temperatures are on the rise and soils are drying out, with the potential for the current dry spell to break a record from 1893 if the weather doesn't change drastically.
Here's a breakdown of what's going on:
The Drought's Toll
"Things aren't looking good," warns ntv.de meteorologist Bjoern Alexander. According to the German Weather Service (DWD), a mere 58 liters per square meter have been recorded nationwide from early March to mid-May. That's less than a third of the usual rainfall for this time of year.
Even compared to the worst drought periods in German weather history, this year stands out. In 1893, the driest spring on record, at least 85.3 liters per square meter fell on average. In 2011, still a dismal second place, it was 89.5 liters per square meter. To avoid a new negative record, Germany would need to see significant rain in the next two weeks, averaging about 25 to 30 liters across the country.
Change in the Weather Only Brings Slight Relief
The gap to an average spring is even larger. "To achieve a balanced rainfall balance by the end of May, about 120 liters per square meter are still needed," says Bjoern Alexander. Even in the best-case scenario of current forecasts, water models only suggest a possible change in weather patterns with rain, delivering 20 to 50 additional liters in some regions. Most regions may see almost no rain in the next seven days.
The maps detail where it's rained the least in the current month of May, and it's clear that even local heavy rain events have hardly made up for the deficit. By the end of May, all station data will fall short of the rainfall target.
Notable Impact on Regions
Brandenburg, including areas near Berlin and parts of the Upper Rhine and western Alpine foothills, are the hardest hit, with the Rhine River experiencing significant drops in water levels.
Central and eastern Europe, including parts of Germany, have seen some improvement by late April, indicating regional variation.
Comparison with Past Drought Periods
While exact historical drought comparisons aren't detailed, this drought is severe enough to disrupt agricultural activities, water supply, energy production, and ecological health. This current drought is exacerbated by record-high temperature anomalies and prolonged rainfall deficits, a combination not typically seen in recent decades.
The escalating European drought crises linked to climate change raise concerns, as rising temperatures and altered precipitation patterns pose increasing risks compared to past dry spells.

Key Regions:
- Brandenburg (incl. near Berlin and the town of Baruth): Often hit the hardest, Brandenburg suffered low rainfall levels in the recent winter, making it particularly vulnerable to water scarcity.
- Upper Rhine Basin: The Rhine River experiences significant water level drops in its upper basin, negatively impacting navigation, industrial use, and energy production.
- Northern and Western Alpine foothills: Parts of the western Alps in Germany exhibit signs of hydrological stress linked to the drought, further aggravating water scarcity issues in the region.
Historical Context: This drought resembles some of the critical recent episodes of water stress. Climate change effects likely contribute to its severity compared to past droughts, although detailed historical data is not provided in the sources.
- In light of the severe drought currentlyaffecting Germany, it would be prudent for both community and employment policies to address the potential impacts on agricultural activities, water supply, and ecological health, given the exacerbating factors of record-high temperature anomalies and prolonged rainfall deficits.
- As questions about the future of environmental-science and climate-change become increasingly pressing, scientists should investigate the role of science and climate-change in aggravating historical droughts such as the current one in Germany, making comparisons to past periods of water stress to shed light on the changing trends in European weather patterns.
