The approach of a cold front on September 5, followed by a polar air mass, is the dominant driver of trader positioning for São Paulo’s daily minimum temperature. Official guidance from INMET, Climatempo, and European models shows the front triggering widespread rain and cloud cover that limits nighttime radiative cooling while shifting winds southerly, with forecast lows clustered between 14–17 °C. Model consensus places the minimum near 15 °C, yet small differences in frontal timing and boundary-layer moisture explain the tight spread across 15–17 °C outcomes. Historical September climatology (average low ~12 °C) and urban heat-island effects add further uncertainty, keeping probabilities distributed rather than concentrated on any single threshold. Updated model runs and surface observations through September 4 will be the next key inputs for traders.

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.
