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 3 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Porto-Novo leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 27 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Porto-Novo
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For oil palm in Porto-Novo, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026 season in Porto-Novo
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to November 2026 |
| Rain in a typical year | About 1,148 mm |
| This season's rain | Leaning dry — September and October 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. |
| What that supports | enough rain for one full main crop, 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 57% of this area. |
| 57% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 260 growing days · about 1,160 mm · March to November |
