Recent cold fronts and a strengthening polar air mass have cooled São Paulo ahead of winter’s official start on June 21, keeping daytime maxima near or slightly below seasonal norms. Official forecasts for June 15 show an overcast sky with showers and a projected high of roughly 18°C (65°F), consistent with the market’s leading 18°C outcome at 43.5% implied probability. Model consensus points to limited daytime warming under persistent cloud cover and northeasterly flow, while historical June data indicate typical highs of 21–22°C can drop 2–4°C when fronts pass. The narrow clustering around 17–19°C reflects low forecast uncertainty for this short-range period, with any break in cloud cover or delayed frontal passage the main variables that could shift the realized maximum.
