**An incoming cold front from southern Brazil is the dominant factor anchoring the 87% market-implied probability on a September 22 high of 24°C or below in São Paulo.** Official and ensemble forecasts from sources including INMET-aligned models and global numerical weather prediction runs show a frente fria arriving around the spring equinox, driving widespread cloud cover, rain totals of 10–16 mm, and suppressed insolation that limits daytime warming. This setup contrasts with September’s climatological average high near 23°C and follows recent warmer days, producing a sharp downward revision in expected maxima to the 22–27°C range across models. Traders are pricing in the front’s timing and intensity as the key variable, with any slower advance or model shift toward greater clearing representing the main upside risk to warmer outcomes before official observations resolve the market.

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 22 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.**An incoming cold front from southern Brazil is the dominant factor anchoring the 87% market-implied probability on a September 22 high of 24°C or below in São Paulo.** Official and ensemble forecasts from sources including INMET-aligned models and global numerical weather prediction runs show a frente fria arriving around the spring equinox, driving widespread cloud cover, rain totals of 10–16 mm, and suppressed insolation that limits daytime warming.
