**Forecast models from sources like the GFS and local meteorological guidance indicate a maximum temperature of 23–24°C in São Paulo on September 22, driven by a polar air mass and associated cold front that have kept the region cooler and wetter than seasonal norms.** Persistent cloud cover, high humidity, and widespread showers or thunderstorms—consistent with September 2026’s record rainfall totals—limit daytime heating, with winds shifting to favor cooler advection from the south. This aligns with the market’s 84% implied probability for 24°C or below, reflecting strong consensus across updated model runs that the peak will stay at or below that threshold. Resolution hinges on official INMET or airport observations, with any unexpected clearing potentially allowing a brief spike toward 25–26°C before the next front reinforces the pattern.

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.
