Across its districtsFrom about 1,031 mm in the driest of 39 districts to about 2,420 mm in the wettest
This season's rainRain close to usual — plan around about 1,945 mm falling roughly when it always does
This season's heatHotter than usual — about +0.9 °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 supportsenough rain for one full main crop, warm all year, so nothing but rain ends the season

Guinea-Bissau's regions

What grows here

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 Guinea-Bissau, 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.

Or check your field first

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.

Frequently asked questions

What crops grow well in Guinea-Bissau?

Cashew, Jute mallow, Okra, Pearl millet, Green gram all rate well in Guinea-Bissau — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Cashew in Guinea-Bissau?

In Guinea-Bissau the window for Cashew runs 7 May 2026 to 4 Oct 2026.

Is there a farming app that works in Guinea-Bissau?

Divisi does. It reads Guinea-Bissau'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 Guinea-Bissau, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.

A district's answer is one question. What to grow, what attacks it and where to sell it are the others.
