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 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Grande Comore (Ngazidja) is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Grande Comore (Ngazidja)
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For cashew in Grande Comore (Ngazidja), the lie of the land is the tightest of the three at 60%. 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 2025 season in Grande Comore (Ngazidja)
| When the rains are expected | September 2025 to September 2025 |
|---|---|
| Rain in a typical year | About 2,140 mm in a typical farming district |
| Across its districts | From about 1,816 mm in the driest of 9 districts to about 2,242 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 2,140 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. |
