Highlights for Msimu rains (November, 2025 – April, 2026)

This statement highlights the evolution of climate systems and outlook for Msimu rains, over the unimodal areas (western, central, southwestern highlands, southern, southern coast, and southern part of Morogoro region) for the months of November, 2025 to April, 2026. Advisories and early warnings have been provided to various weather sensitive sectors such as agriculture and food security, livestock and fisheries, natural resources, wildlife and tourism, energy and water, transport (land – roads and railway, marine and aviation), local authorities, health, private and disaster management. The Outlook for Msimu rains is as follows:

a) Outlook for Msimu rains over Unimodal areas:
i Below Normal to Normal rains are expected over southern Kigoma, Tabora, Katavi, Singida and Dodoma regions. However, Normal to Below Normal rains are expected over Njombe, Iringa, Mbeya, Songwe, Rukwa, Ruvuma, Mtwara and Lindi regions together with the southern part of Morogoro region. The season is likely to be characterized by prolonged dry spells and poor distribution of rainfall over most areas.
ii Rains are expected to commence during the third and fourth week of October, 2025 over Tabora, Katavi and Kigoma regions and spreading to Rukwa, Songwe, Mbeya, Iringa, Njombe regions and southern part of Morogoro region during the second and third week of November, 2025.

b) Expected Impacts
(i) The anticipated Below Normal rains in most areas may result into soil moisture stress, which could affect crop growth and development and reduce yields for rain-fed crops.
(ii) Decrease in reservoir water levels and river flow is likely, which could reduce water availability for various uses.
(iii) The availability of water and pasture for livestock is expected to be affected.
