Forecasts from INMET and global ensembles (ECMWF, GFS) point to a modest daytime maximum near 20°C in São Paulo on August 24 under increasing cloud cover, southeasterly winds of 10–18 km/h, and high humidity that curbs surface heating. Late-winter conditions feature reduced insolation from overcast skies, limited advection of warmer air, and urban heat-island effects that temper overnight lows around 12–15°C. Model spreads in cloud thickness and wind strength create the tight clustering around 19–21°C outcomes, with clearer breaks potentially allowing brief warming to 22°C or thicker stratus suppressing readings to 18°C. Updated model runs and local observations through the evening of August 23 will refine the precise peak before resolution.

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 24 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
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.Forecasts from INMET and global ensembles (ECMWF, GFS) point to a modest daytime maximum near 20°C in São Paulo on August 24 under increasing cloud cover, southeasterly winds of 10–18 km/h, and high humidity that curbs surface heating.
