Gabon Climate – June 2026 Update
Top 5 Cities: Libreville, Port-Gentil, Franceville, Oyem, and Moanda
This month in numbers
Gabon experienced its 3rd warmest June on record, with an average temperature of 24.82°C, marking a significant anomaly of +1.6°C compared to the 1961–1990 baseline. Globally, June 2026 also ranked as the 3rd warmest June for land temperatures, with an anomaly of +1°C. The three-month period from April to June 2026 saw Gabon record its 9th warmest such period on record, with an average temperature of 25.28°C, an anomaly of +1.1°C.
What changed
Gabon's recent warmth is part of a broader trend, with the country's latest full-year average temperature in 2025 being 25.51°C, making it the warmest year on record. The long-term trend shows a warming of +1.38°C against the 1961–1990 baseline. This aligns with the wider African continent, which is warming faster than the global average.
What’s driving change?
The significant warming observed in Gabon is influenced by the broader global climate patterns, including the developing El Niño conditions in the tropical Pacific. The World Meteorological Organization confirmed in June that El Niño is expected to influence weather and climate patterns globally in the coming months. This natural climate oscillation, coupled with the overarching trend of global warming, contributes to the increased temperatures experienced in regions like Gabon. The effect also plays a role in the observed temperature anomalies.
Looking ahead
The developing El Niño event is likely to strengthen into the Northern Hemisphere winter of 2026-27, suggesting a continued influence on global weather patterns in the months ahead.

Shifting Seasons
Wet / dry seasonsKöppen Aw · TropicalGabon doesn't have a warm/cold cycle - its monthly temperature range is only 1.9°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 29× as much rain as the driest). So we track how the wet season has shifted instead.

FAQs
FAQs
How is the climate in Gabon changing?
Gabon 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 Gabon come from?
Climate data for Gabon 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 Gabon climate data cover?
The Gabon climate profile covers Libreville, Port-Gentil, Franceville, Oyem and surrounding areas. Temperature, rainfall and emissions data for Gabon
How often is the Gabon climate update refreshed?
The Gabon 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.
