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 19 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Suba South 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 19 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2025 season in Suba South
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2025 to June 2025 |
| Rain in a typical year | About 853 mm |
| This season's rain | Leaning 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 heat | Hotter than usual — about +0.9 °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 full main crop, 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 34% of this area. |
