The Minister for the Interior, Mohammed-Mubarak Muntaka, has disclosed that Ghana recorded its highest monthly rainfall on record in June 2026, describing the unprecedented downpours as a major factor behind the widespread flooding that affected several parts of the country.
Addressing Parliament on Tuesday, June 30, on the impact of the floods and the government’s emergency response, the Minister said data from the Ghana Meteorological Agency showed that although June is traditionally one of the country’s wettest months, this year’s rainfall far exceeded previous records.
Mr. Muntaka revealed that 169.2 millimetres of rain fell on Monday alone, making it the fourth-highest volume of rainfall recorded in a single day since 1995.
“In the month of June we normally expect a lot of rains. But what happened yesterday gave us 169.2 millimetres of rainfall, and this is the fourth largest volume of rainfall recorded in a single day since 1995,” he told Parliament.
He further disclosed that Ghana recorded a cumulative 593.2 millimetres of rainfall in June, making it the wettest month ever documented in the country’s meteorological history.
“For the month of June, we had a total of 593.2 millimetres of rainfall. It is the highest our country has ever received in its history in one month,” the Minister said.
According to Mr. Muntaka, the previous highest monthly rainfall was recorded in 2002, when 420.6 millimetres of rain fell, followed by 380.3 millimetres in 2015.
“The closest was in 2002 with 420.6 millimetres, and the other was in 2015 with 380.3 millimetres. I will make these statistics available to the House,” he added.
The Interior Minister acknowledged that human activities, including indiscriminate dumping of refuse into drainage systems and the construction of buildings on waterways, contributed significantly to the severity of the flooding.
However, he stressed that the exceptional volume of rainfall meant flooding would likely have occurred even if drainage infrastructure had been properly maintained.
Describing the floods as one of Ghana’s most severe natural disasters in recent years, Mr. Muntaka assured Parliament that the government is working closely with emergency response agencies to provide relief to affected communities while strengthening measures aimed at improving flood resilience, disaster preparedness, and long-term mitigation efforts.
