What grows in Tchiamba-Nzassi
Kouilou, Congo
The 2026/27 season in Tchiamba-Nzassi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to July 2027 |
| Rain in a typical year | About 1,314 mm |
| This season's rain | Leaning dry — January, October, 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 +0.5 °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 97% of this area. |
| 97% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 293 growing days · about 1,340 mm · September to July |
|---|---|
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 295 growing days · about 1,330 mm · September to July |

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.

Is there a farming app that works in Tchiamba-Nzassi?
