This month in numbers
April 2026 in Belgium was notably warm, with an average temperature of 11.48°C, marking an anomaly of +3.4°C compared to the 1961–1990 baseline. This ranked 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.
What changed
The three-month period from February to April 2026 saw an average temperature of 7.57°C, an anomaly of +2.4°C, ranking as the 11th warmest such period on record. This places Belgium 65th globally for its 3-month temperature anomaly. Europe as a whole experienced its second-warmest March on record, with much of the continent seeing dry conditions. Belgium's April anomaly was 0.93°C warmer than the European group average.
What’s driving change?
The warmer conditions in Belgium and across Europe are influenced by several factors. A significant warming driver is the broader trend of land warming faster than the ocean. The current ENSO state is Neutral, with an anomaly of +0.11°C for February-April 2026, though a transition to El Niño is strongly forecast for the coming months, with a 79% probability for June-August 2026. This shift could bring cooler late winters to Northern Europe, though very strong El Niños have historically reversed this trend.
Belgium has also faced a high risk of wildfires in Flanders and Wallonia due to prolonged dry weather and strong easterly winds in late April 2026. This follows a trend of increasing wildfire risk in Belgium due to climate change, with rising temperatures and prolonged droughts. In early April 2026, Brussels experienced a significant water pipe burst, causing an estimated €400,000 in damage and highlighting concerns about aging infrastructure in dense urban areas.
Looking ahead
The NOAA CPC forecast indicates a strong likelihood of El Niño conditions developing in the coming months, with an 87% probability for July-September 2026, which typically brings cooler late winters to Northern Europe.

FAQs
FAQs
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.
Which areas does the Belgium climate data cover?

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.
