This month in numbers
Belgium experienced a significantly warmer April, with the average temperature reaching 11.48°C, an anomaly of +3.4°C compared to the 1961–1990 baseline. This ranks as the 7th warmest April in 86 years of records. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C. The three-month period from February to April 2026 also saw elevated temperatures, ranking as the 11th warmest on record for Belgium, with an average of 7.57°C, an anomaly of +2.4°C.
What changed
The recent three-month period (February–April 2026) in Belgium was notably warmer, continuing a trend seen throughout the past year. Belgium's 1-month anomaly of +3.41°C places it 24th globally out of 234 regions for the latest month's temperature anomaly, and 4th warmest within the Europe group. The country's annual average temperature for 2025 was 11.37°C, making it the 4th warmest year in 85 years of records. This regional warming aligns with the broader global picture, as global land temperatures for February–April 2026 ranked as the 2nd warmest on record.
What’s driving change?
The persistent warmth in Belgium is influenced by a combination of factors. The broader trend of contributes to the significant temperature anomalies observed. Additionally, the can steer winter storms, and its current state would influence regional weather patterns. While the current ENSO state is Neutral, with a +0.11°C anomaly, forecasts indicate a strong likelihood of an El Niño developing by May-July 2026, with probabilities rising to 98% by August-October. Historically, El Niño events have shown a tendency for cooler late winters in Northern Europe, though very strong events have sometimes led to warmer winters. Belgium also experienced thunderstorms on April 18, 2026, with significant lightning activity.
Looking ahead
The strong forecast for an evolving El Niño phase in the coming months suggests a potential shift in weather patterns, with typical teleconnections for Northern Europe indicating a tendency for cooler late winters.

How is the climate in Belgium changing?
Belgium 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 trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Belgium come from?
Climate data for Belgium 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.

How often is the Belgium climate update refreshed?
The Belgium 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.
