Trader consensus on Polymarket overwhelmingly favors 30°C as São Paulo's highest temperature on April 18, 2026, with 100% implied probability, driven by official observational data from INMET stations and the IAG-USP urban monitoring site. Morning lows around 19°C climbed steadily under partly cloudy conditions, peaking at 30°C mid-afternoon amid low humidity (40–70%) and urban heat island amplification, before plateauing as cloud cover increased and evening cooling set in. Forecast models from CPTEC/INPE and INMET align with this, projecting no further intensification. Realistic challenges include an improbable late-day clear-sky surge pushing beyond 30°C or minor measurement revisions from final INMET bulletins, expected post-midnight.
