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 9 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Yarpea Mahn 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 13 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Yarpea Mahn
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 2,107 mm |
| This season's rain | Leaning dry — September and October 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 +0.9 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 90% of this area. |
| 90% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 322 growing days · about 2,100 mm · February to December |
|---|---|
| 10% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 323 growing days · about 2,020 mm · February to December |
