The 2026 season in Osun

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedMarch 2026 to November 2026
Rain in a typical yearAbout 1,251 mm in a typical farming district
Across its districtsFrom about 1,205 mm in the driest of 30 districts to about 1,380 mm in the wettest
This season's rainLeaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early.
This season's heatHotter than usual — about +0.8 °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.

Osun'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 Osun, 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

Frequently asked questions

What crops grow well in Osun?

Cashew, Cucumber, Jute mallow, African nightshade, Pearl millet all rate well in Osun — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Cashew in Osun?

In Osun the window for Cashew runs 28 Feb 2026 to 10 Oct 2026.

Is there a farming app that works in Osun?

Divisi does. It reads Osun'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 Osun, 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.
