The summer of 2026 was the warmest in the Netherlands since national records commenced in 1901. Data from the Royal Netherlands Meteorological Institute (KNMI) shows the average temperature across the three summer months reached 19.3°C at its benchmark station in De Bilt. This figure surpassed the previous record of 18.9°C, which was set in 2018. The season was marked by multiple heatwaves and exceptionally warm nights. In Maastricht, the temperature remained above 22°C for three consecutive nights, a phenomenon recorded for the first time in the Netherlands. The KNMI issued its first-ever code red warning for extreme heat in June. KNMI climate expert Peter Siegmund indicated that a summer with such high temperatures can now be expected approximately once every five years under the current climate conditions. He also stated that under the KNMI's highest climate scenario, a summer like this could be considered average by around 2050. ## Coverage comparison ## What the coverage left out None of the centre or right-rated reports printed below mention the public health institute RIVM's figure of at least 900 excess deaths linked to the June heatwave.
