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 15 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Mbale leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 26 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mbale
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For tomato in Mbale, the lie of the land is the tightest of the three at 88%. 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 Mbale
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to December 2026 |
| Rain in a typical year | About 986 mm |
| This season's rain | Leaning wet — 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 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 52% of this area. |
| 52% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 289 growing days · about 990 mm · February to December |

|---|---|
| Nitrogen (N) | About 99 kg per hectare |
| Phosphate (P₂O₅) | About 27 kg per hectare |
