Forecasts from multiple sources for São Paulo on September 21, 2026, show daytime maxima clustered around 29–32°C under mostly sunny to partly cloudy skies with northerly winds. This positioning reflects model consensus on strong solar heating and limited moisture early in the day, offset by an approaching cold front that could increase afternoon cloud cover or trigger isolated showers, capping the peak. Historical September averages near 23°C highlight the anomalously warm conditions driven by the current synoptic pattern. Traders appear to weigh real-time observational updates against slight divergences in timing of any instability, favoring 30–31°C outcomes while assigning meaningful probability to 28–29°C if cloudiness arrives earlier than expected.

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 21 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.Forecasts from multiple sources for São Paulo on September 21, 2026, show daytime maxima clustered around 29–32°C under mostly sunny to partly cloudy skies with northerly winds.
