Official meteorological observations for São Paulo on June 4 confirm a daily maximum of 21°C, aligning with the strong market consensus. This outcome reflects typical early-winter conditions in the region, where June highs average 21–23°C amid the transition to drier, cooler Southern Hemisphere patterns and reduced solar insolation. National weather service data and station records show minimal deviation from seasonal baselines, with no significant warm advection or urban heat island amplification pushing readings higher. Traders’ near-certain positioning stems from the completed observation window and historical consistency for this date. Only an unforeseen measurement revision or extreme microclimate anomaly could alter resolution.
