Recent forecasts from regional models indicate Sao Paulo's June 26 maximum will likely peak near 20–21°C amid typical austral winter conditions dominated by a subtropical high-pressure ridge, light winds, and variable cloud cover that limits daytime heating. Lingering moisture and cooler air advection from mid-June cold fronts have kept daily highs 1–3°C below seasonal averages, creating tight clustering around these thresholds rather than warmer outcomes. Official monitoring by INMET and ensemble guidance show minor differences in boundary-layer mixing and insolation that differentiate 20°C from 21°C scenarios, with limited upward potential unless clearer skies develop overnight. Traders' near-even split reflects this narrow forecast spread ahead of final observational data.
