The 2026/27 season in Njombe

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedNovember 2026 to June 2027
Rain in a typical yearAbout 1,030 mm in a typical farming district
Across its districtsFrom about 1,012 mm in the driest of 6 districts to about 1,450 mm in the wettest
This season's rainLeaning wet — January, February, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself.
This season's heatHotter than usual — about +1.2 °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.

Njombe's districts

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 Njombe, 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 Njombe?

Guava, Mango, Lemon, Lablab, Maize all rate well in Njombe — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Guava in Njombe?

In Njombe the window for Guava runs 16 Oct 2026 to 23 Feb 2027.

Is there a farming app that works in Njombe?

Divisi does. It reads Njombe'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 Njombe, 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.
