Ghana Climate
Top 5 Cities: Accra, Kumasi, Tamale, Takoradi, and Cape Coast
This month in numbers
Ghana experienced its 7th warmest April on record, with an average temperature of 30.05°C, an anomaly of +1.6°C compared to the 1961–1990 baseline. The period of February–April 2026 ranked as the 4th warmest such period in 86 years of records, with an average temperature of 30.17°C, an anomaly of +1.5°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 globally.
What changed
Ghana's consistently warm temperatures this past season are part of a broader trend, with the country's latest full-year average temperature in 2025 being the warmest on record at 28.3°C. This continues a long-term warming trend of +1.26°C compared to the 1961–1990 baseline. While Ghana's one-month and three-month temperature anomalies place it 128th and 137th respectively out of 234 regions globally, the overall African continent is also experiencing significant warming, with Ghana's April anomaly being 0.17°C warmer than the group average.
What’s driving change?
The elevated temperatures in Ghana are largely influenced by global climate change, with rising temperatures observed year-round and particularly during the dry season. The effect is also contributing to higher temperatures in cities like Accra, where dense infrastructure and human activities lead to significantly warmer conditions compared to rural surroundings. Additionally, pre-onset rains in January and February 2026, driven by the Madden-Julian Oscillation, Atlantic anomalies, and ITCZ movements, have already caused localised flooding and waterlogging across southern Ghana. Heavy rains since late March have also caused flooding in southern Ghana, particularly in Accra.
Looking ahead
Above-normal rainfall is projected along the East Coast and adjoining inland areas of Ghana, including Accra, Tema, Cape Coast, and Koforidua, during April to June, significantly elevating the risk of flooding, flash flooding, and related disasters.

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

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