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 30 Jul 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Haraze Al Biar yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Haraze Al Biar
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | July 2027 to September 2027 |
| Rain in a typical year | About 343 mm |
| This season's rain | Rain close to usual — plan around about 343 mm falling roughly when it always does |
| This season's heat | Hotter 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. |
| 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 90% of this area. |
| 90% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 91 growing days · about 360 mm · July to September |
|---|---|
| 10% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 280 mm · July to September |
