In strong contrast to 2024, 2025's season featured minimal hail activity, with the largest stones reaching 2,5 cm (~1 inch) in size on two occasions, namely June 1 and August 23. In 2024, by contrast, the largest stone reached ~10 cm, four times the size of 2025's largest.

With over 20 reports (21), the tornado count so far is hugging the upper-bound of DNSROP's forecast of 14-22, marking a significantly more active season than initially thought. This is in part due to a rather favorable end to July/start August...

CFS forecasts suggest the same from July to August this year. Using this, we can publish a rough estimate of the tornado count for 2025.
From May to September, the likely number of tornadoes in Denmark will be around 14-22 tornadoes (2004-2024 average of 14.5 tornadoes).

2024, 2022 and 2019 (etc.) were active storm-wise, but what did they have in common?
A quasi-stationary Icelandic low-pressure area, below-average precipitation and temperature anomalies over the North Sea, and higher precipitation and temperature anomalies over Denmark and Sweden.
