Guinea Climate
Top 5 Cities: Conakry, Nzérékoré, Kindia, Kankan, and Labé
This month in numbers
Guinea experienced its 11th warmest April on record in 2026, with an average temperature of 29.24°C, marking an anomaly of +0.9°C compared to the 1961–1990 baseline. The three-month period from February to April 2026 was the 3rd warmest on record for Guinea, with an average temperature of 28.94°C, an anomaly of +1.2°C. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with the February–April period also ranking as the 2nd warmest for global land temperatures.
What changed
Guinea's consistently warm temperatures over the past three months align with a long-term warming trend for the country, which has seen an increase of +0.99°C against the 1961–1990 baseline. The year 2025 was the warmest on record for Guinea, at 26.88°C. This persistent warmth is occurring during an ENSO-neutral phase, though El Niño is strongly forecast to develop in the coming months, typically bringing drier conditions to Sahelian Africa, which includes Guinea. Guinea also saw a notable concentration of wildfire activity, with three events occurring between April 19 and May 5, representing 100% of the past 12 months' total for the region.
What’s driving change?
The sustained warmth in Guinea is influenced by the broader , where tropical regions already experience high temperatures close to human heat tolerance limits. While the current ENSO state is neutral, with an anomaly of +0.11°C, there is a strong forecast for an El Niño to develop, with a 61% probability for May–July and increasing to 87% for July–September. El Niño events are generally associated with drier conditions in Sahelian Africa, which could further exacerbate heat in Guinea. The recent cluster of wildfires in Guinea, with three events between April 19 and May 5, is an unusual concentration for the region and can be tracked on our Extreme Weather tracker page. Long-term data also indicates severe to exceptional drought conditions along the West African coastal zone, including Guinea, from April 2025 through March 2026.
Looking ahead
The strong forecast for an El Niño developing in the coming months suggests a likelihood of drier conditions for Guinea in the latter half of the year, which could impact agricultural activities.

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 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 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.

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.
