The 2026/27 season in Rorya

Rainy seasonsOne each year — one chance to plant, so timing carries it
When the rains are expectedSeptember 2026 to June 2027
Rain in a typical yearAbout 858 mm
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 +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.
