Public concern regarding extreme weather in the Netherlands has risen, with a survey indicating that 63% of citizens are worried about local impacts such as heavy rainfall, heatwaves, and drought. In the province of Limburg, concern reached 75%, a trend experts link to the visible impact of the 2021 floods.

By late August 2026, the Netherlands officially recorded its warmest summer since 1901. According to the Royal Netherlands Meteorological Institute (KNMI), the average temperature at the De Bilt station reached 19.3 degrees Celsius, surpassing the previous record set in 2018. Extreme heat was particularly notable in the south, where Maastricht recorded three consecutive nights with temperatures remaining above 22 degrees Celsius, a first in Dutch meteorological history.

In response to these shifts, regional authorities are implementing adaptation strategies. In Leeuwarden, the municipality is adjusting urban greenery to withstand extreme drought and heavy rainfall, noting that thousands of trees are currently in poor condition. Additionally, in the Overijssel region, Waterschap Vechtstromen has partnered with German municipalities to improve water retention to mitigate both summer droughts and winter flooding risks. Experts warn that such extremes could become the norm by 2050.
