Official meteorological observations for São Paulo on September 11 confirmed a daily maximum of 28°C, aligning with the market's near-certain outcome. Spring conditions featured predominantly clear skies and light northerly winds that permitted daytime warming consistent with climatological averages near 25–27°C, while afternoon humidity and minor cloud development prevented further rise. Multiple station reports, including airport data, recorded this peak without exceeding it, providing the verifiable threshold that resolved trader consensus. Minor variations in microclimate or reporting timing represent the only realistic scenarios that could have altered the exact figure, though none materialized in final datasets.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 11 Sep '26.
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.Official meteorological observations for São Paulo on September 11 confirmed a daily maximum of 28°C, aligning with the market's near-certain outcome.
