The 2026/27 season in Maswa

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedOctober 2026 to May 2027
Rain in a typical yearAbout 663 mm
This season's rainLeaning wet — January, 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 +0.9 °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.

Plan the season, not just check it

The crops and dates above are read at cells spread across Maswa, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions

What crops grow well in Maswa?

Bambara groundnut, Cashew, Common bean, Cotton, Cowpea all rate well in Maswa — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Bambara groundnut in Maswa?

In Maswa the window for Bambara groundnut runs 7 Oct 2026 to 26 Nov 2026.

Is there a farming app that works in Maswa?

Divisi does. It reads Maswa'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 Maswa, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
