Current forecasts from sources like AccuWeather and numerical models indicate Sao Paulo highs on July 20 will likely reach 27–28°C, aligning with the market's leading 28°C outcome at 49% implied probability. This reflects typical mid-winter conditions in the Southern Hemisphere, where average July maxima hover near 23–26°C, but recent model runs show modest warming from northerly flow and clearer skies boosting daytime temperatures. Uncertainties in exact peak readings stem from local urban heat effects and minor forecast adjustments, with resolution hinging on official station data. Traders appear to weigh historical July extremes and ensemble consensus when positioning around these thresholds.
