Recent forecast guidance from multiple models shows Sao Paulo highs on September 4 clustering in the upper 20s to low 30s °C, with northwest flow and limited cloud cover supporting peak readings near 29 °C. This aligns with the market's heaviest trading around 28–30 °C, as ensembles indicate modest warming from the cooler September 2–3 period amid typical early-spring subtropical patterns. Scattered thunderstorm chances introduce minor uncertainty in exact maxima, while climatological September averages near 23–25 °C provide context for the elevated outlook. Updated model runs and official monitoring agency guidance over the next 48 hours remain the key variables that could shift implied probabilities before resolution.

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.
