ICPAC calls for early action ahead of JJAS rains

The IGAD Climate Prediction and Applications Centre (ICPAC) is calling on regional and national authorities across the Greater Horn of Africa (GHA) to take proactive steps following the release of its June to September (JJAS) seasonal forecast during the 70th Greater Horn of Africa Climate Outlook Forum (GHACOF 70).

According to ICPAC, above-normal rainfall is anticipated across most parts of the GHA, with particular significance for countries in the northern and western subregions. In some areas such as parts of Sudan—this season accounts for over 90% of the annual rainfall, and more than 40% in others.

The forecast has critical implications for key sectors including agriculture, water resource management, disaster risk reduction, and food security.

In a press statement, ICPAC noted: “There is a 55% probability of above-normal rainfall over central Sudan, eastern South Sudan, northern and southwestern Ethiopia, western Kenya, and eastern Uganda. Additionally, wetter-than-average conditions (approximately 45% probability) are expected in western Uganda, South Sudan, southern Sudan, Djibouti, and western Eritrea.”

However, the outlook also highlights areas of concern, with a high likelihood of below-average rainfall predicted for the coastal regions of Somalia and Kenya, northwestern South Sudan, and southeastern Ethiopia.

Most parts of the region are expected to receive near-normal rainfall, though early onset is likely in some areas. In contrast, a delayed start to the rainy season is expected in parts of western Ethiopia.

Meanwhile, southern GHA countries such as Tanzania, Rwanda, and Burundi are projected to remain largely dry, as the JJAS period is not typically their main rainy season.

The temperature forecast indicates a strong likelihood of warmer-than-average conditions across much of the region, particularly over southern Ethiopia and Somalia, eastern Kenya, and northern Sudan. Conversely, average to below-average temperatures are expected in the IGAD-Karamoja cluster, Djibouti, Eritrea, central Sudan, and northeastern Ethiopia.

“The Greater Horn of Africa is experiencing unprecedented climate extremes, ranging from droughts and floods to unpredictable rainfall, putting our food systems, water resources, and livelihoods at serious risk. We must institutionalize climate services and work together across borders and sectors to ensure climate risks are integrated into every decision. The future of our region depends on it,” said Mohamed Ware, Deputy Executive Secretary of IGAD.

Eng. Dr. Habtamu Itefa, the Minister of Water and Energy of the Federal Democratic Republic of Ethiopia, highlighted the need for continued investment.

“We must continue to invest in and expand systems capable of generating knowledge-based, user-tailored climate information. This is essential for guiding policy decisions and reaching grassroots communities most vulnerable to climate risks.”

Furthermore, Dr. Abdi Fidar, the Officer in Charge at ICPAC, highlighted the significance of GHACOF as a regional platform.

“GHACOF continues to be a leading platform in our region where climate experts, decision-makers, and stakeholders co-produce and share actionable climate information that shapes preparedness and response at national and regional levels.”

JJAS is a critical rainy season for countries in the northern and western parts of the GHA. It contributes to over 50% of annual rainfall over the northern parts of GHA region, and more than 80% in most parts of Sudan, making the seasonal forecast particularly significant for early action and planning in sectors such as Agriculture and food security, water resources, disaster risk reduction, and in other climate-sensitive socio-economic sectors.

GHACOF 70 was convened as a hybrid event from 19–20 May 2025 by ICPAC, in collaboration with National Meteorological and Hydrological Services (NMHSs) and regional partners.

The primary objective of the forum was to issue the seasonal forecast for the June to September 2025 rainfall season.
