The 2026/27 season in Bongolava

Rainy seasons	One each year — one chance to plant, so timing carries it
When the rains are expected	October 2026 to April 2027
Rain in a typical year	About 1,702 mm in a typical farming district
Across its districts	From about 1,692 mm in the driest of 2 districts to about 1,702 mm in the wettest
This season's rain	Leaning 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 heat	Hotter than usual — about +1.2 °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 that supports	enough rain for one full main crop, warm all year, so nothing but rain ends the season
Ground this covers	One kind of ground throughout.
