Recent forecasts indicate an approaching cold front will bring increased cloud cover, showers, and thunderstorms to São Paulo on September 1, limiting solar heating and suppressing the daily maximum. Model consensus from sources like the Met Office and local agencies points to highs near 22–25 °C amid northerly or northwesterly flow and elevated humidity, well below the 32–36 °C readings seen in late August under a warm, dry air mass. Trader sentiment clusters tightly around 23–24 °C because small differences in the exact timing of frontal passage, rainfall intensity, and boundary-layer mixing can shift the peak by 1–2 °C. Historical September averages near 23 °C provide a baseline, but the current synoptic shift favors the lower end of the distribution.

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.
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.
