Recent model runs and surface observations indicate Sao Paulo's overnight low on September 6 will likely settle between 8–12 °C, driven by a persistent southeasterly flow advecting cooler, moist maritime air behind a frontal passage. High humidity near 90 % combined with overcast skies and light rain has limited daytime heating to around 12–14 °C while promoting gradual nocturnal cooling under building high pressure. Ensemble forecasts show tight clustering in this range, with minor differences arising from exact timing of any clearing and wind speeds that could enhance or suppress radiative losses. Historical early-September minima average near 12 °C, so the current setup represents a modest cool anomaly that keeps probabilities tightly bunched across the 8–12 °C outcomes.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 6 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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 model runs and surface observations indicate Sao Paulo's overnight low on September 6 will likely settle between 8–12 °C, driven by a persistent southeasterly flow advecting cooler, moist maritime air behind a frontal passage.
