Official meteorological observations from São Paulo stations, including Congonhas Airport, recorded a minimum temperature of 16°C overnight into September 22, 2026, under clear to partly cloudy skies with light southerly winds and dew points near saturation. This aligns with regional model consensus from GFS runs and climatological baselines for late September, when nocturnal radiative cooling typically bottoms out near 13–16°C absent strong frontal systems. The 100% market-implied odds reflect verified station data confirming this exact threshold. Potential challenges include post-event quality-control revisions by national weather services or discrepancies between airport and urban microclimate readings exceeding 1°C.

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.
