Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Brazil’s INMET/CPTEC models indicate a peak temperature near 23–28°C for São Paulo on May 17, driven by a persistent subtropical ridge advecting warmer air masses with limited frontal passage. This setup supports the market’s 75% implied probability on 23°C or higher, well above the city’s May climatological average high of 22–23°C at São Paulo-Guarulhos International Airport. Light winds and partial cloud cover are expected to reduce nocturnal cooling, while historical analogs from early-to-mid May show similar synoptic patterns rarely producing highs below 23°C absent an unexpected cold front. Updated model runs scheduled for tomorrow morning will provide final guidance ahead of resolution.
