The 2026/27 season in Sumbawanga

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedNovember 2026 to May 2027
Rain in a typical yearAbout 743 mm
This season's rainLeaning wet — January, February, March, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself.
This season's heatHotter than usual — about +1.0 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can.

Frequently asked questions

What crops grow well in Sumbawanga?

Common bean, Finger millet, Fonio, Groundnut, Guava all rate well in Sumbawanga — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Common bean in Sumbawanga?

In Sumbawanga the window for Common bean runs 25 Oct 2026 to 22 Feb 2027.

Is there a farming app that works in Sumbawanga?

Divisi does. It reads Sumbawanga's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.

Is this exact for my own field?

No — these are readings taken across Sumbawanga, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
