Rio de Janeiro 2026-09-25

A single day could bring around 14mm of rain on 2026-10-01 — above the local heavy-rain reference for this time of year (around 3.7mm in a day). Construction, drainage, and outdoor events should review schedules.

6 dry days in a row could start 2026-09-25. A dry day here means 1mm of rain or less; the important number is the length of the run. Crops in flowering or fruit-set windows are most exposed.
