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 31 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Haraze Mangueigne is close to normal, so these dates match the pattern the area usually follows.
Planting after 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Haraze Mangueigne
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to October 2027 |
| Rain in a typical year | About 636 mm |
| This season's rain | Rain close to usual — plan around about 636 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 | 2 kinds of ground. The season below is the largest that farms — about 96% of this area. |
| 96% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 150 growing days · about 710 mm · May to October |
|---|---|
| 4% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 199 growing days · about 850 mm · May to November |
