**Recent model consensus points to a significant cooldown in São Paulo on September 5 driven by an advancing cold front or low-pressure system, shifting conditions from the clear, warm highs of 27–31°C seen on September 3–4.** Cloud cover, widespread showers or thunderstorms, and southerly or southeasterly flow are expected to limit daytime heating, with official and ensemble guidance converging on a maximum around 20–23°C. Key variables differentiating the closely matched 20–22°C market leaders include the precise timing of precipitation onset, total cloud thickness, and boundary-layer moisture, all of which reduce insolation and evaporative cooling. Historical September variability in the region and the short lead time amplify uncertainty in model runs, keeping trader-implied probabilities tightly clustered while emphasizing the value of updated NHC-style or regional meteorological briefings.

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.
