Recent cool, overcast conditions with southeast winds and scattered showers have kept Sao Paulo temperatures below seasonal norms, with official observations around 13°C today. Multiple forecast models converge on a modest rebound for September 8, with highs most likely reaching 19–21°C under persistent cloud cover that limits daytime heating while allowing gradual warming from the east. Key variables include the exact timing of any clearing and moisture advection, which could push the maximum to 22°C or hold it at 19°C depending on model runs. Trader consensus around these narrow outcomes reflects the narrow uncertainty range in short-range guidance from agencies like INMET and international ensembles, with resolution hinging on the official daily maximum recorded at Congonhas or comparable stations.

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 8 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 cool, overcast conditions with southeast winds and scattered showers have kept Sao Paulo temperatures below seasonal norms, with official observations around 13°C today.
