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 3 Jul 2027. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Assin South leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.

Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Assin South

When the rains are expected	February 2026 to December 2026
Rain in a typical year	About 1,345 mm
This season's rain	Leaning dry — February, 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 +0.8 °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	One kind of ground throughout.
