Rain in a typical yearAbout 1,458 mm in a typical farming district

Rainy seasons, district by districtOf 3 districts: one rainy season in 2 and two rainy seasons in 1
This season's rainLeaning wet — January, February, October, 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 +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 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.

Frequently asked questions

What crops grow well in Tharaka-Nithi?

Is there a farming app that works in Tharaka-Nithi?

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