**Persistent cloud cover, widespread rain, and northerly winds have suppressed daytime heating across São Paulo on September 20, 2026, keeping surface temperatures well below seasonal norms.** Multiple forecast models and real-time observations indicate a daily maximum of 20–23 °C at most official stations, with thick low- and mid-level clouds limiting solar insolation and evaporative cooling from showers further capping the peak. This aligns with the market’s overwhelming 99.9 % implied probability for 21 °C or below, reflecting traders’ assessment of current INMET and global model consensus rather than any guarantee. The only realistic challenge would be an unexpected late-day clearing that allows brief additional warming at the primary recording site, though current conditions make this highly improbable.

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 20 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.**Persistent cloud cover, widespread rain, and northerly winds have suppressed daytime heating across São Paulo on September 20, 2026, keeping surface temperatures well below seasonal norms.** Multiple forecast models and real-time observations indicate a daily maximum of 20–23 °C at most official stations, with thick low- and mid-level clouds limiting solar insolation and evaporative cooling from showers further capping the peak.
