A cold front advancing from the south is the dominant driver suppressing maximum temperatures in São Paulo on September 6, with widespread cloud cover, moderate to heavy rain, and southerly winds limiting daytime solar heating and advecting cooler air masses. Official and ensemble model guidance from sources such as INMET-aligned forecasts and ECMWF runs shows daytime highs clustered around 15–17 °C under overcast conditions and 80–100 % precipitation probability, consistent with the market’s tight clustering on 16 °C (34.5 %) and 17 °C (28.0 %). Differentiation among the leading outcomes hinges on small variations in frontal timing, rainfall intensity, and boundary-layer mixing; stronger or earlier southerly flow and thicker stratiform clouds would favor 15 °C or below, while partial clearing or weaker winds could allow brief warming toward 18 °C. Historical September climatology for the region places typical maxima near 22–24 °C, underscoring the anomalous cooling expected tomorrow.

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 that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
