Recent GFS and multi-model forecasts for São Paulo indicate a daytime high near 28°C on September 25 under building high pressure, reduced cloud cover, and light northerly or variable winds that limit cooling. Ensemble guidance shows limited spread, with most solutions clustered between 27–29°C, consistent with springtime warming trends that exceed the September climatological average of roughly 23–25°C. Light precipitation chances appear too low to suppress maximum temperatures meaningfully. Traders appear to weight the latest model consensus and historical verification of similar setups, producing the current market-implied probabilities centered on 27–29°C ahead of final pre-event updates.

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.
