Intense rainfall anticipated nationwide due to 'heavy downpours' in Denmark
A low-pressure system over Denmark combined with humid and unstable air is expected to bring more cloudbursts, sudden downpours with 15 millimetres of rain falling within half an hour, into Friday evening across several parts of the country. The Danish Meteorological Agency (DMI) has issued a heavy rain alert for most of Denmark on Friday and part of the country on Saturday.
On July 21–22, 2025, Denmark experienced a historic heavy rain event, with the DMI issuing its first-ever red alert for dangerous rainfall, particularly affecting southeastern Denmark. During this period, more than 130 mm (5.1 inches) of rain fell in localized areas such as Møn island and Neble, significantly exceeding the usual monthly average for July.
The rainfall was caused by a stationary frontal system that produced persistent and concentrated precipitation, leading to concerns about urban flooding, overwhelmed drainage systems, and impacts on infrastructure. The red alert spanned from Monday afternoon through Tuesday evening and included red and orange warnings issued by DMI across large parts of the country, excluding Bornholm.
Following this event, heavy rain and possible cloudbursts were forecast for western Denmark due to an approaching low-pressure system expected to remain almost stationary for several days into early August, potentially continuing to bring heavy precipitation to parts of the country.
Regarding weather system movement, the heavy rain is expected to move northeastward into southern Sweden with the most intense downpours shifting toward the southern highlands of Sweden, where thunderstorms may also occur. Sweden has not issued severe weather warnings in connection with this rainfall moving in.
The weather on Sunday is not forecast to be much of an improvement, with temperatures reaching no more than 20 degrees Celsius and sporadic showers. However, there will be marked differences between regions over the weekend, with some areas potentially remaining dry. No new information about the current status of the cloudburst alerts is given.
This is the third consecutive year in which so much rain has fallen in July that the month has been added to the list of Denmark's ten wettest Julys on record. No new areas have been added to the list, and last month joined the list following the historic rain event in July 2025.

- Amidst the ongoing concern about the approaching low-pressure system, the Danish Meteorological Institute (DMI) has suggested that the increasing interest in environmental-science, specifically weather-related, becomes essential to mitigate potential effects such as urban flooding and infrastructure damage.
- As the nation recovers from the historic heavy rain event in 2025, which saw the involvement of art students documenting the damage through their work, the importance of science's role in predicting such events and providing information to the public remains paramount, according to recent news reports.
