Recent forecasts for São Paulo on September 2, 2026, point to overnight lows near 11–14 °C amid a spring transition featuring possible polar air incursions and variable cloud cover. Model consensus shows modest disagreement on the strength of nocturnal radiative cooling and any southeasterly wind advection, which can suppress or enhance temperature drops under clear versus overcast skies. Historical September minima average around 12–15 °C, but atypical frontal frequency this season adds uncertainty to exact thresholds. With outcomes clustered tightly between 9–19 °C, traders appear focused on subtle differences in forecast soundings, dew-point depressions, and urban heat-island effects that determine whether the daily minimum settles near 11 °C, 13 °C, or slightly higher. Updated model runs and official monitoring agency guidance in the next 24–48 hours will likely refine these probabilities.

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 2 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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 for São Paulo on September 2, 2026, point to overnight lows near 11–14 °C amid a spring transition featuring possible polar air incursions and variable cloud cover.
