The 2026/27 season in Isandra

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedOctober 2026 to April 2027
Rain in a typical yearAbout 1,176 mm
This season's rainLeaning dry — January, February and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early.
This season's heatHotter than usual — about +1.3 °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.

Plan the season, not just check it

Is there a farming app that works in Isandra?

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