| When the rains are expected | September 2025 to September 2025 |
|---|---|
| Rain in a typical year | About 1,960 mm in a typical farming district |
| Across its districts | From about 1,817 mm in the driest of 7 districts to about 2,644 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 1,960 mm falling roughly when it always does |

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.
Plan the season, not just check it
The crops above are gathered from every district in Atsinanana, and the ground under them is not all the same. 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.
This calendar moves
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.

Is there a farming app that works in Atsinanana?
Divisi does. It reads Atsinanana'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 Atsinanana, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
