Algeria Climate
Top 5 Cities: Algiers, Oran, Constantine, Annaba, and Blida
This month in numbers
Algeria experienced its 8th warmest April on record, with an average temperature of 24.92°C, marking an anomaly of +2.7°C compared to the 1961–1990 baseline. The period of February to April 2026 was the 6th warmest on record, with an average of 20.52°C, an anomaly of +2.3°C. Globally, April 2026 was the 2nd warmest April for land temperatures, with a +1.1°C anomaly, while the February–April period also ranked as the 2nd warmest globally, with a +1.2°C anomaly.
What changed
Algeria's recent warmth follows a trend, with 2025 being the warmest year on record. The country's 1-month temperature anomaly of +2.7°C places it as the warmest in the Africa group, significantly higher than the group's average of +1.38°C. This past month also saw a notable concentration of flood events, with a single flood event in early May representing 100% of the annual total for Algeria, an unusual occurrence for the region and season.
What’s driving change?
The persistent warmth in Algeria is influenced by the broader trend of land warming faster than ocean. The current ENSO state is Neutral, with a +0.11°C anomaly, though forecasts indicate a strong likelihood of El Niño developing from May–July 2026 onwards, with a 61% chance, rising to 87% by July–September. El Niño typically brings warmer, drier conditions to the Mediterranean region during summer, amplifying heatwave and wildfire risks. Algeria also experienced heavy rains and thunderstorms in late April and early May, leading to flash floods that tragically claimed at least seven lives in early May. Prior to this, in March, some areas of Algeria even experienced heavy snowfall.
Looking ahead
The evolving El Niño phase suggests a heightened risk of hotter, drier conditions for Algeria in the coming months, particularly during summer.

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.

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.
