Madagascar
The 2026/27 season in Diana
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to May 2027 |
| Rain in a typical year | About 2,237 mm in a typical farming district |
| Across its districts | From about 1,257 mm in the driest of 5 districts to about 2,237 mm in the wettest |
| This season's rain | Leaning dry — January, 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 +1.1 °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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 76% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 208 growing days · about 1,660 mm · October to May |
|---|---|
| 10% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 156 growing days · about 1,250 mm · November to April |

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.
What grows here with irrigation
Plan the season, not just check it
The crops above are gathered from every district in Diana, 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.

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 Diana?
Groundnut, Maize, Sesame, Cashew, Guava all rate well in Diana — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Groundnut in Diana?
In Diana the window for Groundnut runs 4 Oct 2026 to 1 Feb 2027.
Is there a farming app that works in Diana?
Divisi does. It reads Diana'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 Diana, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
