Denmark Climate – June 2026 Update
Top 5 Cities: Copenhagen, Aarhus, Odense, Aalborg, and Esbjerg
This month in numbers
Denmark experienced its 5th warmest April–June period on record, with an average temperature of 11.89°C, a significant 1.8°C above the 1961–1990 baseline. June 2026 itself was notably warm, ranking as the 21st warmest June in 86 years, with an average temperature of 15.06°C, which is 0.7°C above the baseline. Globally, June 2026 was the 3rd warmest June on record for land temperatures, and the April–June period ranked as the 2nd warmest globally for land temperatures.
What changed
The warmer trend observed in Denmark over the past three months aligns with a broader pattern of elevated temperatures across Europe. Denmark's 1-month anomaly of +0.74°C places it 166th out of 234 regions globally, while Europe as a whole saw a 1-month anomaly of +2.56°C, indicating that while Denmark was warmer than average, other parts of Europe experienced even more pronounced heat. The country's latest full-year average temperature for 2025 was 9.9°C, making it the 3rd warmest year on record.
What’s driving change?
The significant warming experienced in Denmark, particularly the record-breaking heat in June, was driven by a heat dome that brought an unusually warm air mass north from continental Europe. On June 27, 2026, Denmark recorded its hottest day ever, reaching 37.0°C in Ødum and Beldringe, surpassing the previous national record from 1975. This extreme heat was part of a wider European heatwave, with several countries reporting exceptional temperatures. The current weak El Niño, with a +0.98°C anomaly in the NOAA ONI 3-month (AMJ 2026), is also a contributing factor to global temperature patterns, and is forecast to continue as a strong El Niño through the end of 2026.
Looking ahead
With El Niño conditions forecast to persist and strengthen through the end of 2026, there is an increased likelihood of above-normal temperatures globally in the coming months, though specific regional impacts for Denmark remain subject to other evolving climate drivers.

Shifting Seasons
Warm / cold seasonsKöppen Dfb · ContinentalHow spring and autumn have shifted in Denmark. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (7.7°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 16.5°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Denmark changing?
Denmark 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 Denmark come from?
Climate data for Denmark 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 Denmark climate data cover?

How often is the Denmark climate update refreshed?
The Denmark 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. See the Climate Rankings for cross-region comparisons.
