Ghana has experienced recurrent heavy rainfall and flooding for decades, particularly during the major rainy season between April and June and the minor rainy season from September to November. Rapid urbanization, poor drainage systems, settlement in flood-prone areas, and climate variability have contributed to increasingly severe flood events.
Notable Flood Events
1930s–2000s: Historical records indicate that Accra has experienced repeated urban flooding since the 1930s, with major flood events recorded in 1955, 1960, 1963, 1973, 1986, 1991, 1995, 1999, 2001, 2002, 2010, and 2011.
June 2015: One of Ghana’s deadliest flood disasters occurred after torrential rains inundated Accra. Flooding, combined with a petrol station explosion, claimed more than 200 lives and caused widespread destruction of homes, businesses, and infrastructure.
2020:
Heavy rains caused widespread flooding across parts of Accra, disrupting transport and damaging homes and businesses.
2021: Severe floods affected the Ashanti and Upper West regions, resulting in fatalities, destruction of roads and bridges, and displacement of hundreds of residents.
2023: Heavy rainfall and the controlled spillage of the Akosombo and Kpong dams caused extensive flooding in the Volta, Eastern, and Greater Accra regions, displacing more than 26,000 people and damaging farms, schools, and public infrastructure.
2025:
Heavy rains again triggered flooding in Accra and surrounding communities, prompting emergency response efforts and renewed calls for improved drainage systems, stricter land-use planning, and stronger disaster preparedness.
These recurring events highlight the urgent need for sustainable urban planning, improved drainage infrastructure, effective waste management, and climate-resilient disaster risk reduction strategies across Ghana.
