**Forecast models for São Paulo on September 2, 2026, show a cooling trend driven by a passing cold front and southeasterly winds advecting cooler maritime air from the South Atlantic.** Recent observations indicate highs near 26–33°C on August 31–September 1 before the shift, with September 2 expected to peak in the 19–21°C range under partly cloudy skies and light-to-moderate winds (roughly 10–20 km/h). Cloud cover and any residual moisture limit daytime heating, keeping maximum temperatures below the September climatological average of ~23°C. Official and ensemble guidance (including hourly profiles peaking near 20°C) supports this narrow band, with minor model spread on exact timing of clearing or wind shifts creating the tight market clustering around 19–21°C. Resolution hinges on official station readings (typically Congonhas or official INMET data) for the daily maximum.

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 which 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 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.
