Trader consensus on Polymarket closely splits between 29°C (39%) and 30°C (34%) for São Paulo's highest temperature today, driven by INMET's latest forecast of a 31°C peak amid partly cloudy conditions and isolated afternoon convective showers, tempered by high humidity fostering instability. Above the April historical average of 26°C, current atmospheric patterns feature lingering heat from high-pressure dominance per INMET's monthly outlook released three days ago, but traders discount full realization due to potential cloud cover reducing insolation during peak afternoon heating (2-4 p.m. local time). Key differentiators include sea breeze timing and shower coverage; real-time data from official stations like IAG-USP or INMET monitors will clarify as the day progresses toward evening resolution.
