| When to plant | 27 Nov 2026 – 6 Jan 2027 opens in 8 weeks | 27 Dec 2026 – 9 Aug 2027 |
| Expected harvest | about 1.0 t/ha | about 1.5 t/ha |
| Harvest | From 27 Mar 2027 to 5 Jul 2027, depending on the planting date | |

| Rain meets its needs | 86% | |
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 27 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Guijá 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 6 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Guijá
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to April 2027 |
| Rain in a typical year | About 593 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 +1.7 °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 short crop, and only if timed to it, 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 96% of this area. |
| 96% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 163 growing days · about 600 mm · November to April |
|---|---|
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 182 growing days · about 720 mm · November to May |
