The Netherlands has issued its first-ever Code Red heat alert as temperatures are set to soar to 40°C tomorrow, marking an unprecedented escalation in the country’s weather warnings. The Royal Netherlands Meteorological Institute (KNMI) activated the highest-level alert at midnight on Thursday, warning that extreme heat poses severe risks to public health, including dehydration, heatstroke, and life-threatening heat exhaustion. The alert covers large parts of the country and remains in effect through Friday, with daytime temperatures unlikely to drop below 30°C until at least next week .
Belgium has also shattered records, with 34.2°C measured in Uccle on Thursday, surpassing the previous daily high set in 1976 . The extreme conditions have triggered infrastructure strain, including buckled road surfaces and warped railway tracks, disrupting transport across both nations .
The heatwave coincides with a thunderstorm warning for Friday afternoon, adding another layer of risk as storms could exacerbate heat-related hazards. The KNMI’s decision to issue Code Red reflects the accelerating impact of climate change, with heatwaves becoming more frequent and intense. “The first national heatwave of the year is now official,” the KNMI confirmed on Thursday, noting that such events are “no longer rare” due to global warming .
Across Europe, the crisis has already claimed lives. In France, a toddler died after being trapped in a hot car while their mother slept, as Paris recorded temperatures above 40°C for the first time in 150 years . Germany, meanwhile, braces for up to 43°C, with the German Weather Service warning of a “heat dome” gripping the continent .
Authorities in the Netherlands are urging residents to take precautions, including staying hydrated, avoiding outdoor activities during peak heat, and checking on vulnerable neighbors. The KNMI’s unprecedented alert underscores the urgent need for adaptation as extreme weather events become the new norm. With no relief expected until next week, the coming days will test the resilience of communities and infrastructure alike.
