Ghana recorded its highest monthly rainfall since 1995 in June 2026, a development that significantly contributed to the devastating floods that swept through parts of the Greater Accra Region, Interior Minister Mohammed Muntaka Mubarak has disclosed.
Speaking in Parliament on Tuesday, June 30, the Minister revealed that a total of 593.2 millimetres of rainfall was recorded in June, making it the highest monthly rainfall figure documented in the country over the last three decades.
He explained that the heavy downpour on Monday, June 29, alone produced 169.2 millimetres of rainfall within 24 hours, ranking as the fourth-highest daily rainfall recorded since 1995.
According to Muntaka, previous major rainfall records included 420.6 millimetres in 2002 and 380.3 millimetres in 2015.
The Minister noted that although human activities such as indiscriminate dumping of refuse into drains and the construction of buildings on waterways worsened the flooding situation, the extraordinary amount of rainfall would have placed enormous pressure on drainage systems regardless.
“Naturally, it clearly shows that even if we had everything right, the kind of rains that we received in June and yesterday would have necessarily created some overflow and created some problem for us,” he told Parliament.
Muntaka also disclosed that weather authorities had indicated shortly before midnight that conditions were likely to deteriorate, but the full scale of the rainfall that followed could not have been accurately predicted at the time.
His comments come as government agencies continue rescue, relief and recovery operations in flood-affected communities across Greater Accra. The floods have resulted in deaths, displaced thousands of residents and caused extensive damage to homes, businesses and public infrastructure.
Authorities are urging residents to remain vigilant as the rainy season continues, while efforts are underway to provide assistance to affected families and assess the full extent of the destruction.
