Here Is What You Need To Know About The March-May Rainy Season

The Uganda National Meteorological Authority (UNMA) on February 20, 2018 released Uganda’s  seasonal climate outlook for March to May of this year.

March to May (MAM) constitutes the first major rainfall season in Uganda. During the 48th Climate Outlook Forum for the Greater Horn of Africa held in Mombasa, Kenya from 12th to 13th February 2018, the national, regional and international climate scientists reviewed the state of the global climate system and its implications on the seasonal rainfall over the East African region.

Dr. Festus Luboyera, the Executive Director at UNMA said overall, there is an increased probability for near normal rainfall over much of Uganda, except the western sector of the country which is expected to receive normal to above normal rainfall.

“It should be noted that the onset of seasonal rains is expected to be characterised by severe thunderstorms and hailstorms over several parts of the country,” he said.

 Eastern Uganda

Eastern Lake Victoria and South Eastern (Jinja, Mayuge, Kamuli, Iganga, Bugiri, Namayingo, Luuka, Namutumba, Buyende, Kaliro, Busia and Tororo) districts have been experiencing dry conditions since December 2017.

The onset of seasonal rains is expected around late February to early March and the peak is expected around mid to late April through early May. The cessation is expected around late May. Overall, this region has a high chance of receiving near normal rainfall.

The Implications Of The Current Forecast

Generally, most areas around the country are expected to receive near normal with a slight tendency to above normal in some areas, UNMA boss said.

“The implication is that these areas will receive rainfall within average range and in some areas above the average of their respective long term means. Rainfall is expected to adequately support the normal socio-economic activities for the various sectors,” he said, adding that there are high chances that Eastern Karamoja region, parts of Isingiro and Rakai,  and parts of Pakwach and Nebbi are expected to experience below normal rainfall during this season. This implies that the total rainfall expected over these regions is below 75% of the Long Term Mean (LTM).
