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 27 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.Forecast models from Brazilian meteorological services and international agencies converge on a daytime peak of 27–28°C for São Paulo on August 27 under mostly sunny skies with light northeasterly winds and low humidity after morning fog dissipates. This places the highest temperature near the seasonal average for late winter, driven by strong solar insolation at 23.5°S latitude, minimal cloud cover reducing albedo effects, and urban heat retention in the metropolitan area. Slight model spread around exact maximum arises from uncertainties in boundary-layer mixing and any residual moisture advection, keeping 27°C and 28°C outcomes nearly tied in trader-implied probabilities while higher or lower thresholds remain low-probability outliers.
