Netherlands Climate – June 2026 Update
Top 5 Cities: Amsterdam, Rotterdam, The Hague, Utrecht, and Eindhoven
This month in numbers
June 2026 was exceptionally warm for the Netherlands, ranking as the 3rd warmest June on record with an average temperature of 17.96°C, a significant +2.9°C above the 1961–1990 baseline. This contributed to an equally warm spring, with the April–June 2026 period also ranking as the 3rd warmest on record, at 14.26°C, an anomaly of +2.5°C. Globally, June 2026 was the 3rd warmest June for land temperatures, and the April–June period ranked as the 2nd warmest globally for land temperatures.
What changed
The Netherlands experienced a pronounced heatwave in June, with temperatures locally reaching up to 40°C. This led the Royal Netherlands Meteorological Institute (KNMI) to issue its first-ever Code Red warning for extreme heat on June 26, 2026. The heatwave was particularly notable in the central weather station of De Bilt, which recorded its hottest June day ever at 36.8°C, and in Ell, which saw a scorching 39.4°C. This regional heatwave, which lasted 12 consecutive days in De Bilt, was the 40th official national heatwave since 1901 and set an all-time record for the most heatwave days in June. Western Europe as a whole experienced its warmest June on record.
What’s driving change?
The extreme warmth in the Netherlands and across Western Europe in June was significantly influenced by a strengthening El Niño event. The current weak El Niño, with a NOAA ONI 3-month anomaly of +0.98°C for April-June 2026, is forecast to persist and potentially intensify, with a 100% probability of El Niño conditions through the end of the year. This El Niño is contributing to persistently warm ocean temperatures globally, which in turn exacerbates land heatwaves. The warming trend is also consistent with the broader , where higher-latitude regions like the Netherlands are warming faster than the global average. The Netherlands' 1-month anomaly was 0.30°C warmer than the European group average, highlighting the regional intensity of the heat.
Looking ahead
Above-average heat is projected to return to the Netherlands in the coming weeks, with temperatures potentially climbing back past 26°C by mid-July and entering the low 30s by the end of next week. The strengthening El Niño is expected to continue influencing global weather patterns, with potential for more intense rainfall and storms in the Netherlands in the coming months.

Shifting Seasons
Warm / cold seasonsKöppen Cfb · TemperateHow spring and autumn have shifted in Netherlands. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (9.5°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 15.3°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Netherlands changing?
Netherlands is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
Where does the climate data for Netherlands come from?
Climate data for Netherlands comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Netherlands climate data cover?

How often is the Netherlands climate update refreshed?
The Netherlands climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update.
