What grows in Onesi
Omusati, Namibia
The 2026/27 season in Onesi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | December 2026 to April 2027 |
| Rain in a typical year | About 517 mm |
| This season's rain | Rain close to usual — plan around about 517 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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. |
| What that supports | enough rain for one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

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.
What grows in Onesi with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it
The crops and dates above are read at cells spread across Onesi, 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 Onesi?
Finger millet, Soybean, Bambara groundnut, Fonio, Lablab all rate well in Onesi — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Finger millet in Onesi?
In Onesi the window for Finger millet runs 2 Dec 2026 to 11 Jan 2027.
Is there a farming app that works in Onesi?
Divisi does. It reads Onesi'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 Onesi, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
