The closely matched probabilities for 21–22°C as the highest temperature in São Paulo on August 26 reflect model consensus on typical late-winter conditions under a dominant subtropical high-pressure ridge, with modest variability from the precise timing and strength of any weak frontal passages. Official forecasts from INMET and international ensembles such as ECMWF and GFS show daily maxima centered near the climatological August average of 21–23°C, where differences of 1–2°C hinge on boundary-layer moisture, cloud cover reducing daytime heating, and local urban heat-island effects. Traders are weighting the narrow spread because fresh model runs overnight will clarify whether a slightly stronger northerly flow or clearer skies push the outcome toward 23°C or keep it at 20–21°C.

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.
