Rainy seasons, district by districtOf 6 districts: one rainy season in 1 and two rainy seasons in 1
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 +1.0 °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.

Siaya's districts

What grows here

Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.

Plan the season, not just check it

The crops above are gathered from every district in Siaya, and the ground under them is not all the same. 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.

Or check your field first

Planting windows shift with the forecast. Leave your email and we'll send what changed, and a note when planting time nears — a couple of emails a month at most.

Frequently asked questions

What crops grow well in Siaya?

Cassava, Pineapple, Cashew, Mango, Pearl millet all rate well in Siaya — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Cassava in Siaya?

In Siaya the window for Cassava runs 30 Sep 2026 to 20 Oct 2026.

Is there a farming app that works in Siaya?

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

A district's answer is one question. What to grow, what attacks it and where to sell it are the others.
