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 16 Oct 2026. That is the point in the window where the rains are most reliably established.

No seasonal forecast reaches Maputsoe yet, so these dates follow the rains it usually gets rather than this year's.

Planting after 16 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

This season's rainLeaning dry — January, February, November and December 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 heatHotter than usual — about +1.8 °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.
