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 22 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Arib is close to normal, so these dates match the pattern the area usually follows.
Planting after 12 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Arib
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For sweet orange in Arib, the lie of the land is the tightest of the three at 30%. 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 Arib
| When the rains are expected | October 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 653 mm |
| This season's rain | Rain close to usual — plan around about 653 mm falling roughly when it always does |
| 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 | 2 kinds of ground. The season below is the largest that farms — about 92% of this area. |
| 92% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 222 growing days · about 660 mm · October to April |
