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 31 Dec 2026. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Manonyane 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 31 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Manonyane

Rain and temperature 96%
The soil 96%
The lie of the land 76%

For watermelon in Manonyane, the lie of the land is the tightest of the three at 76%. 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 2026/27 season in Manonyane

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedOctober 2026 to May 2027
Rain in a typical yearAbout 706 mm
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.

Phosphate (P₂O₅)About 15 kg per hectare

These are the nutrients a watermelon crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
