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 14 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ekurhuleni 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 24 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Ekurhuleni
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to April 2027 |
| Rain in a typical year | About 672 mm |
| This season's rain | Leaning 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 heat | Hotter than usual — about +1.9 °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 one full main crop, warm, with a cool spell that slows winter growth |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 87% of this area. |
| 87% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 195 growing days · about 660 mm · October to April |
|---|---|
| 8% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 196 growing days · about 670 mm · October to April |
| 4% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 191 growing days · about 660 mm · October to April |

What it takes to grow sesame in Ekurhuleni

| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
