Press Release


African Center of Meteorological Applications for Development (ACMAD) in collaboration with the AGRHYMET Center, the National Meteorological service of Ghana and technical partners organizes the Seasonal Forecasting Workshop on agro-hydro-climatic characteristics of the main rainfall season in the Gulf of Guinea countries (PRESAGG-11).

The Regional Climate Outlook Forum for the Gulf of Guinea Region 2024 edition is organized within the framework of the “Climate Services and Applications (ClimSA)” program, with the support and coordination of the (ACMAD), under the lead of AGRHYMET.

Each year, extreme weather, hydrological and climatic disasters (severe storms, floods, heat waves and droughts) cause loss of life and significant socio-economic impacts, significantly compromising socio-economic development and growth, in particular in countries low resources.

The PRESAGG was initiated in 2014 in collaboration with meteorological services, regional and international institutions in response to the need for information on the climate of the Gulf of Guinea to better manage climate risks in this region.

The forum will be followed by the development by each country of detailed national seasonal forecasts with alert information through the national climate outlook forums, the results of which will be communicated to decision-makers and the general public. ACMAD supports countries in pilot initiatives for the production, communication and use of localized seasonal forecasts.


The overall objective of the forum is to contribute to strengthening the resilience of the populations of the Gulf of Guinea in the face of climatic hazards during the period March-April-May-June 2024. This is done through training, production of forecasting, interaction with users / decision makers and communication during the forum.

The specific objectives are to:

  • Strengthen the capacity of participants on the technics of analysis and characterization of agro-hydro-climatic risks related to the main rainy season for the Gulf of Guinea countries.
  • Generate the seasonal forecast of agro-hydro-climatic characteristics (cumulative MAM and AMJ rainfall, onset and cessation dates of the agronomic season, dry spells, rivers basins runoff);
  • Discuss with partners (users, decision makers, etc.) in particular different Users Interface platforms (UIPs), on the results of seasonal forecasts in order to better adapt these products to their needs and take into account this information in their planning;
  • Develop and disseminate recommendations and a press release to users (end-users/farmers, decision makers and other technical partners


  • The staff of the National Meteorological and Hydrological Services (NMHS) of the Gulf of Guinea countries are able to characterize and forecast the agro-hydro-climatic risks of the major rainy season;
  • Seasonal forecasts of the rainfall characteristics of the mean season in the Gulf of Guinea countries are issued;
  • The users interface platforms (UIPs) are operationalized;
  • Current products are adapted to the needs of users for more efficient and targeted use;
  • Press release on risks and specific measures to be taken to reduce vulnerability in the Gulf of Guinea countries is issued.
