Official meteorological observations from stations in São Paulo recorded a daily maximum of 21°C on September 2, 2026, driving the market's near-certain consensus on this outcome. This aligns with regional weather patterns featuring increased cloud cover and moderate southerly flow that limited daytime heating below typical early-spring averages around 23–26°C. Forecasters from agencies like INMET noted stable atmospheric conditions with no significant warm advection or clear-sky amplification. While rare calibration discrepancies across monitoring sites or post-hoc data revisions could theoretically alter the official reading, such adjustments are highly improbable given multiple station agreement and real-time verification protocols.

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 2 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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 from stations in São Paulo recorded a daily maximum of 21°C on September 2, 2026, driving the market's near-certain consensus on this outcome.
