The 2026 season in Isiolo South

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedOctober 2026 to December 2026
Rain in a typical yearAbout 346 mm
This season's rainLeaning wet — 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 +0.8 °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.

Is there a farming app that works in Isiolo South?

Is this exact for my own field?

No — these are readings taken across Isiolo South, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
