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 22 Jun 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Ahafo Ano South West yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 1 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ahafo Ano South West
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For sweet potato in Ahafo Ano South West, 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 2026 season in Ahafo Ano South West
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,242 mm |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| 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 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 63% of this area. |
