**Official meteorological observations from São Paulo on September 21, 2026, recorded a daily maximum of 31°C under clear skies and northerly winds, aligning with the market's near-certain 31°C outcome.** Spring conditions featured above-average warmth for the season, with afternoon peaks driven by strong solar heating and minimal cloud cover, consistent with regional model consensus from agencies like INMET. Historical September maxima typically range 23–29°C, making this reading notable but within observed variability. The overwhelming trader consensus reflects verified station data and rapid post-event confirmation, leaving little room for revision. Only a significant discrepancy in official reporting or station-specific anomalies could shift resolution, though such adjustments remain rare once preliminary readings are validated.

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.
