Globally, June 2026 was the 3rd warmest June on record for land temperatures, and the April–June period was the 2nd warmest on record.
What changed
Benin's consistently warm temperatures this past month and season stand in contrast to some global trends, though the overall picture remains one of significant warming. The country's latest monthly anomaly of +1.35°C placed it 101st out of 234 regions in cross-region rankings, while its 3-month anomaly of +1.48°C placed it 124th. The country's long-term warming trend shows an increase of +1.14°C against the 1961–1990 baseline, with 2025 being the warmest year on record at 28.35°C.
What’s driving change?
The persistent warmth in Benin is consistent with the global trend of . Additionally, the region has been experiencing significant rainfall and associated flooding. Heavy rains in late June led to severe flooding in Abomey-Calavi, disrupting traffic and inundating several roads. The commune of Lokossa also faced serious flooding at the end of June, impacting 180 households and causing significant material and agricultural damage. These events are part of a broader pattern of severe rains and flooding across West Africa, which scientists warn are becoming more frequent and intense due to climate change.
Looking ahead
Weather forecasts for the June to August period indicate a high likelihood of near-average precipitation across most producing areas, with above-average rainfall expected in parts of western and southern regions, which may increase the risk of localised flooding.

FAQs
How is the climate in Benin changing?
Benin 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 Benin come from?
Climate data for Benin 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 Benin climate data cover?
The Benin climate profile covers Cotonou, Porto-Novo, Parakou, Abomey-Calavi and surrounding areas. Temperature, rainfall and emissions data for Benin
How often is the Benin climate update refreshed?
The Benin 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.
