Ghana recorded slightly below-average rainfall in 2025, according to the State of the Climate Report presented by the Ghana Meteorological Agency (GMet).
The report, launched as part of Meteorological Awareness Month, provides a detailed assessment of the country’s climate conditions and highlights emerging weather trends that could affect agriculture, water resources and energy production.
Data in the report shows that Ghana recorded 1,166 millimetres of rainfall in 2025, compared with the long-term national average of 1,191 millimetres recorded between 1991 and 2020, representing a 2.1 percent rainfall deficit.
Rainfall distribution varied significantly across the country. The coastal town of Axim recorded the highest rainfall of 2,056 mm, while Tema recorded the lowest rainfall of 602 mm during the year.
Seasonal rainfall analysis showed several periods of below-average rainfall. During the March–April–May (MAM) season, Ghana recorded 314 mm of rainfall, about 9 percent below the long-term average of 345 mm.
The April–May–June (AMJ) season recorded 455 mm, slightly below the average of 467 mm, while the May–June–July (MJJ) period recorded 427 mm, about 12 percent below its long-term average.
The June–July–August (JJA) season experienced an even larger deficit of about 22 percent, indicating reduced rainfall during the peak of the farming season.
However, rainfall levels improved later in the year. The September–October–November (SON) season recorded 393 mm, representing about 16 percent above the long-term average, providing some relief to farmers and water resources.
Director-General of GMet, Eric Asuman said climate data collected from weather stations across the country shows that rainfall patterns are becoming increasingly variable, with some communities experiencing heavy rainfall and flooding while others record prolonged dry periods.
He noted that such variations raise concerns about water availability, agricultural productivity and hydropower generation, which depend heavily on rainfall and environmental conditions.
According to him, the report provides critical climate information that helps bring together sectors such as agriculture, energy and water management, enabling government institutions and stakeholders to plan effectively and reduce climate risks.
