A cold front advancing into São Paulo on September 5–6, followed by a polar air mass, is the dominant driver pushing trader probabilities toward a lowest temperature near 10–11°C on September 7. Official forecasts from Climatempo and INMET highlight strong southerly winds and cloud cover limiting daytime recovery, with overnight radiative cooling under the stable post-frontal environment setting the daily minimum. Model consensus shows temperatures falling to 9–12°C, though slight variations in front timing, wind speed, and urban heat retention create the observed spread across 8–15°C outcomes. Historical September lows average near 14°C, underscoring how this Arctic outbreak deviates from climatology. Final resolution hinges on INMET station readings at Congonhas or official minimum reports, with any late-model shifts in frontal speed able to adjust the exact threshold.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
