This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 3 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=sbgr If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent forecasts from multiple meteorological sources converge on a daytime high of 26–28°C for São Paulo on September 3, 2026, under mostly clear skies and light northerly winds that favor strong daytime heating after a cooler, cloudier September 2. This springtime setup features increasing solar insolation typical of early September, with low humidity and minimal precipitation supporting peak temperatures near the market’s leading 27°C and 28°C outcomes. Model spreads arise from subtle differences in boundary-layer mixing and urban heat retention, while historical September averages around 23°C provide context for the current warmer anomaly. Updated model runs and afternoon observations will refine the exact maximum before resolution.
