Trader consensus on Polymarket heavily favors 29°C (41.5%) or 30°C (33%) as São Paulo's highest temperature today, reflecting closely matched forecast ensembles from INMET and Climatempo projecting maxima of 29°C amid morning sunshine and high-pressure dominance. Differentiating factors include afternoon convective cloud development and sea breeze incursions, which could cap heating at 29°C per Climatempo's hourly outlook (peak near 14h before 85% rain chance), or permit a 30°C spike if showers delay under drier subtropical air. Recent INMET bulletins for March 30–April 6 noted elevated regional highs (30–34°C nearby), refining odds upward from prior 28°C leans based on satellite-derived stability indices. Official station data, like Congonhas Airport, will resolve amid April's climatological average of 26°C boosted by urban heat island effects; monitor hourly updates for shifts.
