Top 5 Cities: Accra, Kumasi, Tamale, Takoradi, and Cape Coast

This month in numbers

Ghana experienced its 6th warmest June on record, with an average temperature of 27.28°C, an anomaly of +1.2°C compared to the 1961–1990 baseline. This follows a trend of elevated temperatures, as the April–June 2026 period also ranked as the 7th warmest on record, with an average of 28.66°C, an anomaly of +1.3°C. Globally, June 2026 was the 3rd warmest on record for land temperatures, and the April–June period was the 2nd warmest.

What changed

Ghana's consistently warm temperatures this past month and season align with a broader warming trend. The country's average temperature for 2025 was 28.3°C, making it the warmest year on record since 1941. This contributes to a long-term warming trend of +1.26°C compared to the 1961–1990 baseline. Ghana's 1-month temperature anomaly for June 2026 placed it 120th out of 234 regions globally.

What’s driving change?

The persistent warming in Ghana is largely driven by the broader global trend of . Additionally, Ghana experienced catastrophic flooding at the end of June 2026, particularly in the Greater Accra, Central, and Western regions. This event, described by the Ghana Meteorological Agency as a "classical textbook case" of prolonged and intense rainfall, resulted in at least 12 fatalities and displaced nearly 39,000 people in the Greater Accra Region alone. June 2026 recorded the highest monthly rainfall in Ghana's history, with 593.2 millimetres, surpassing previous records. The intense rainfall is linked to climate change making extreme weather events more frequent and intense, with warmer atmospheric temperatures holding more moisture. Urbanisation without adequate drainage planning and encroachment on waterways also exacerbated the flood impact. More information on extreme weather events can be found at Extreme Weather tracker.

Looking ahead

The evolving climate patterns suggest a continued need for vigilance regarding extreme weather events in the coming months.

Shifting Seasons

Wet / dry seasonsKöppen Aw · Tropical

Ghana doesn't have a warm/cold cycle - its monthly temperature range is only 4.2°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 19× as much rain as the driest). So we track how the wet season has shifted instead.

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 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 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.
