Trader consensus on Polymarket assigns a 42.5% implied probability to a 28°C high in São Paulo today, aligning closely with the latest guidance from Brazil's National Institute of Meteorology (INMET) and Climatempo, which forecast a peak of 28°C between 2–4 p.m. under dominant high-pressure systems fostering sunny mornings and light northwest winds up to 12 km/h. Yesterday's observed maximum of 27°C provides a recent baseline amid slightly above-normal early April temperatures (historical average ~26°C), while increasing afternoon clouds and a 90% chance of showers—potentially totaling 20 mm—could cap readings at 27°C (22.5% odds) or allow 29°C (30.5%) if precipitation delays. Real-time data from official stations like Congonhas will refine outcomes as the day progresses.
