São Paulo's recorded temperature fell to 15.8 C on 21 August 2026, down from 25.2 C the previous day, according to a reading DRM3's instrument took of the Open-Meteo public feed.[^1]

The gap between the two readings is 9.4 C across 24 hours, by this paper's arithmetic - a notable single-day swing in either direction.

What would confirm whether that movement reflects a broader weather pattern is a longer run of readings from the same feed. The record here covers two days, and two days is where it stops.

## What this stands on
