The Ghana Meteorological Agency (GMet) has said the 2020 major rainy season will start from March and will last till June 2020.
It said the prediction is based on observations of conditions on land and ocean as well as outputs from major world forecast centres like the International Research Institute for Climate and Society (IRI), Climate Prediction Centre (NCEP-CPC), the European Centre for Medium-Range Weather Forecast (ECMWF), UK Met Office and Meteo France.
In its seasonal rainfall forecast, the agency said “above normal” rainfall should be expected for the period of March, April and May within the forest zones while normal rainfall can be expected for the rest of the country.
Within the season, GMet predicts that there will be slightly longer days of no rain.
“March, April, May and June is the major rainfall season for the south of the country 8°N and below as well the Gulf of Guinea coast. At the peak of the MAM/AMJ season, there is a high probability of heavy rains accompanied by strong winds and lightning which could lead to localized floods. There is also a high probability of experiencing relatively long dry spells at the beginning and towards the end of the season,” it said in the forecast.
Noting that the onset of rains will commence on different dates within the period, GMet said areas within the forest zone will see rains much earlier than other parts of the country.
Areas along the western coast of the country will start experiencing rains between the first and fourth week of March while those lying on the eastern coast will have the season start for them between the second week of March and the second week of April.
The Upper West will have the rainy season starting between the third week of April and the first week of May while the Upper East area will be the last in the country to get into the rainy season.
The season starts between the fourth week of April and the second week of May.
