Recent record rainfall across São Paulo in September 2026 has sustained extensive cloud cover and suppressed daytime heating, driving trader consensus toward a cooler maximum near 21–23°C. Official forecasts from multiple models converge on highs of 20–24°C under overcast skies and light winds, well below the long-term September average of 24–26°C. Persistent moisture from the wettest September on record continues to limit solar insolation and maintain a stable, cooler boundary layer. With resolution tied to verified maximum observations, any late-day clearing or model shift could nudge probabilities, though current conditions strongly favor outcomes at or below 23°C.

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.
