**Forecast models indicate a mild winter day in São Paulo on August 26, 2026, with afternoon highs most likely settling near the 21–22 °C climatological average.** Late-August conditions typically feature highs of 18–24 °C under variable subtropical high pressure, modulated by passing mid-latitude systems. Recent guidance shows increasing cloud cover and possible late-day showers that reduce incoming solar radiation and enhance evaporative cooling, capping temperatures. These factors keep 21 °C and 22 °C as the closest outcomes while leaving modest probability for 20 °C if a cooler air mass arrives earlier or for 23 °C if skies clear longer. Ensemble spread in steering winds and boundary-layer moisture explains the tight clustering around the mean, with traders weighting official numerical weather prediction consensus heavily given the short forecast horizon.

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 26 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 indicate a mild winter day in São Paulo on August 26, 2026, with afternoon highs most likely settling near the 21–22 °C climatological average.** Late-August conditions typically feature highs of 18–24 °C under variable subtropical high pressure, modulated by passing mid-latitude systems.
