Moravia is currently facing a more severe drought situation than the rest of the Czech Republic, with conditions expected to worsen in the coming days. According to climatologist Pavel Zahradníček, there is almost no rain forecasted for at least the next five days, and no significant precipitation is expected until the end of next week.
Drivers of the Current Drought
The intensity of the current drought stems from a combination of long-term factors. Beyond the lack of recent rainfall, Zahradníček cites a significant deficit in winter snowfall and an exceptionally dry spring as primary causes. While short-term rainfall can temporarily improve soil moisture in the top 40 centimeters, the deeper layers—between 40 and 100 centimeters—remain critically dry. This deep-layer deficit indicates a long-term drought that cannot be easily reversed without sustained, widespread precipitation.

Impacts on Energy and Agriculture
The environmental strain is translating into tangible economic and operational consequences. Water levels in rivers have dropped significantly, with the website raft.cz indicating that most rivers are currently unnavigable. Furthermore, the drought is affecting energy production; Zahradníček reports that water-based electricity generation has fallen by 35% compared to normal levels. This reduction in output could potentially influence electricity prices.
Farmers are already bracing for losses, estimating crop yield reductions between 10 and 40 percent. Zahradníček notes that these figures are comparable to the drought years of 2012 and 2018. In 2012, crop yields reached their lowest point in 60 years. Beyond agriculture, forests are also at risk, with the potential for widespread drying as the lack of deep-soil moisture persists.
Expert Insight: The Shift in Weather Patterns
Expert Insight: The current crisis highlights a fundamental shift in the Czech climate. Even when annual rainfall totals remain consistent with historical averages, the landscape is struggling. The core issue is a change in the timing and distribution of rain: we are seeing less spring precipitation and more intense, short-lived storms that cause rapid runoff rather than soaking into the soil. Combined with rising average temperatures that increase evaporation and reduce winter snowpack, the environment is increasingly prone to drought even during years with standard rainfall.
Future Outlook and Variability
While the immediate forecast points toward a worsening situation, the long-term outlook remains uncertain. According to Zahradníček, there is a 30 to 50 percent chance of conditions improving under standard weather patterns. However, he warns that the climate is becoming more volatile, citing the year 2020, which began with a severe drought in April but transitioned into floods by June and October. He advises that the country should prepare for more frequent and intense drought events in the future, mirroring the patterns observed between 2015 and 2020.
Frequently Asked Questions
Why is the landscape still green if there is a drought?
According to Zahradníček, vegetation can remain green if there is enough residual moisture in the upper soil layers to sustain it. However, this can be misleading, as a deficit in deeper soil layers serves as a warning that plants may face severe water shortages in the coming weeks or months.
What is the main cause of the current drought?
The drought is attributed to a combination of low precipitation, a lack of winter snow, and an exceptionally dry spring, all exacerbated by rising air temperatures that increase evaporation.
Could the situation change quickly?
Yes, the situation is variable. While there is a chance of improvement under standard weather conditions, extreme swings are possible, as seen in 2020 when a severe spring drought was followed by summer and autumn flooding.
