When the rains are expectedSeptember 2026 to May 2027
Rain in a typical yearAbout 993 mm
This season's rainLeaning 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 heatHotter than usual — about +1.0 °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.

Plan the season, not just check it

The crops and dates above are read at cells spread across Chahna, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Planting windows shift with the forecast. Leave your email and we'll send what changed, and a note when planting time nears — a couple of emails a month at most.

Frequently asked questions

What crops grow well in Chahna?

Sweet orange, Mandarin, Beetroot, Lettuce, African nightshade all rate well in Chahna — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Sweet orange in Chahna?

In Chahna the window for Sweet orange runs 4 Sep 2026 to 24 Sep 2026.

Is there a farming app that works in Chahna?

Divisi does. It reads Chahna's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.

Is this exact for my own field?

No — these are readings taken across Chahna, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
