Guinea Climate – June 2026 Update
Top 5 Cities: Conakry, Nzérékoré, Kindia, Kankan, and Labé
This month in numbers
Guinea experienced its 8th warmest June on record, with an average temperature of 26.06°C, marking an anomaly of +0.9°C compared to the 1961–1990 baseline. The April–June 2026 period was the 13th warmest on record for the country, with an average temperature of 27.62°C, an anomaly of +0.8°C. Globally, June 2026 was the 3rd warmest June for land temperatures, and the April–June period ranked as the 2nd warmest globally for land temperatures, both with an anomaly of +1°C.
What changed
Guinea's recent warmth aligns with a broader trend, as the country's average temperature for 2025 was 26.88°C, making it the warmest year on record since 1941. The long-term trend for Guinea shows a warming of +0.99°C against the 1961–1990 baseline. While Guinea ranked 146th globally for its June 2026 temperature anomaly and 195th for the April–June anomaly, the overall global picture indicates significant warming, with 10 of the top 10 warmest countries for the latest month's anomaly being countries.
What’s driving change?
The persistent warmth in Guinea is part of a global trend amplified by the , where tropical regions already sit close to the limits of human heat tolerance. The presence of El Niño is also a significant factor, as it is expected to drive hotter temperatures globally, with its effects amplified by long-term climate change. Additionally, observed and forecasted above-average rainfall along West Africa's Gulf of Guinea coast, including parts of northern Guinea, is likely to lead to flooding.
Looking ahead
Near to above-average temperatures are very likely across most parts of Africa, including Guinea, during the July to October 2026 period.

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

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