Trader consensus on Polymarket prices a 45% implied probability for a 30°C high in São Paulo today, with 29°C at 34.5%, reflecting the latest forecasts from INMET and Climatempo indicating mostly sunny skies and highs near 30°C under a persistent subtropical high-pressure system over southeast Brazil. This stable anticyclone, in place since late last week, promotes subsidence that suppresses clouds and enhances daytime heating during the autumnal diurnal cycle, pushing temperatures slightly above the March climatological average of 27°C at official stations like Congonhas Airport. Isolated showers earlier in the week have dissipated, but minor model divergences on afternoon cloudiness introduce uncertainty, with real-time observations expected to resolve the market by evening.
