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.
If you only get one chance to plant, aim for around 5 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mbadjini Est is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mbadjini Est
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For sunflower in Mbadjini Est, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The 2026 season in Mbadjini Est
| When the rains are expected | September 2026 to September 2026 |
|---|---|
| Rain in a typical year | About 2,098 mm |
| This season's rain | Rain close to usual — plan around about 2,098 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.7 °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. |
