This month in numbers
Algeria experienced its 8th warmest April on record in 2026, with an average temperature of 24.92°C, marking an anomaly of +2.7°C compared to the 1961–1990 baseline. The three-month period from February to April 2026 was the 6th warmest on record, with an average temperature of 20.52°C, an anomaly of +2.3°C. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C, while the February-April period also ranked as the 2nd warmest globally, with an anomaly of +1.2°C.
What changed
Algeria's recent warmth is part of a longer-term trend, with 2025 being the warmest year on record for the country, at 25.35°C. The country's long-term trend shows a warming of +2.00°C compared to the 1961–1990 baseline. Algeria's April 2026 anomaly of +2.7°C was notably warmer than the average for the Africa group, which saw a +1.38°C anomaly, making Algeria the warmest in its group for the month.
What’s driving change?
The significant warming observed in Algeria is largely driven by the broader pattern of , where land regions heat up at a quicker rate than oceanic areas. Additionally, the region has been experiencing prolonged periods of water scarcity and drought, which can contribute to , further intensifying heat. While the current ENSO state is Neutral, with a +0.11°C anomaly, forecasts indicate a strong likelihood of El Niño developing in the coming months, with an 82% chance for May-July and increasing to 98% by August-October. El Niño typically brings warmer and drier conditions to the Mediterranean region during summer, which could amplify heatwave and wildfire risks. Algeria has also experienced several extreme weather events recently, including severe storms and heavy rainfall in late January and early April 2026, which caused flooding and fatalities in various provinces. Hail accumulations were also reported in April.
Looking ahead
The forecast for the coming months suggests a high probability of El Niño developing, which typically correlates with warmer and drier conditions for Algeria during the summer, potentially increasing the risk of heatwaves and wildfires.

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

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