Recent forecasts from multiple meteorological sources indicate São Paulo will see increased cloud cover and scattered showers or thunderstorms on September 5, driven by an approaching frontal system that has already lowered temperatures from the 25–27°C highs of early September. This setup favors a daily maximum near 21–23°C, as reduced solar insolation and evaporative cooling from rain limit surface heating compared to clearer conditions earlier in the week. Historical September maxima average around 23°C, but the expected moisture and wind patterns add downward pressure. Model consensus remains tight on the cooler regime, though slight variations in timing or intensity of precipitation could shift the peak by 1–2°C, aligning with the closely matched market probabilities around 20–22°C. Updated National Meteorological Service runs and satellite observations over the next 48 hours will refine these details.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 5 Sep '26.
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.Recent forecasts from multiple meteorological sources indicate São Paulo will see increased cloud cover and scattered showers or thunderstorms on September 5, driven by an approaching frontal system that has already lowered temperatures from the 25–27°C highs of early September.
