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 6 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Umgungundlovu 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 16 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

| The lie of the land | 76% |
For swiss chard in Umgungundlovu, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Umgungundlovu
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to May 2027 |
| Rain in a typical year | About 748 mm |
| This season's rain | Leaning dry — January, February, October, 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 +1.4 °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 | 4 kinds of ground. The season below is the largest that farms — about 54% of this area. |
| 54% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 234 growing days · about 800 mm · September to May |
|---|---|
| 33% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 236 growing days · about 860 mm · September to May |
| 8% | enough rain for a long crop, or two in a year; warm, with a cool spell that slows winter growth 272 growing days · about 870 mm · August to May |
| 3% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 273 growing days · about 930 mm · September to June |
