The 2026/27 season in Nyanza

When the rains are expectedAugust 2026 to July 2027
Rain in a typical yearAbout 981 mm
This season's rainLeaning wet — January, February, 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 +1.2 °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

Frequently asked questions

What crops grow well in Nyanza?

Avocado, Arabica coffee, Enset, Finger millet, Guava all rate well in Nyanza — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Avocado in Nyanza?

In Nyanza the window for Avocado runs 8 Sep 2026 to 19 Mar 2027.

Is there a farming app that works in Nyanza?

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