The 2026/27 season in Tharaka

Rainy seasonsTwo each year — two chances to plant
When the rains are expectedOctober 2026 to January 2027
Rain in a typical yearAbout 579 mm
This season's rainLeaning wet — January, 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.

Frequently asked questions

What crops grow well in Tharaka?

Common bean, Egusi melon, Green gram, Lablab, Pearl millet all rate well in Tharaka — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Common bean in Tharaka?

In Tharaka the window for Common bean runs 26 Sep 2026 to 26 Oct 2026.

Is there a farming app that works in Tharaka?

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