Current forecasts for São Paulo indicate a minimum temperature near 18–20 °C on September 20, with high uncertainty arising from persistent cloud cover, scattered rain, and variable northerly winds that limit radiative cooling overnight. Model spreads in boundary-layer mixing and dew-point depression create tight probabilities across the 14–18 °C range, as clearer breaks could allow greater surface heat loss while continued moisture and urban heat-island effects hold temperatures higher. Official monitoring from INMET and regional analyses show September climatology typically features lows around 14–16 °C, but today’s stable pressure and humidity favor the warmer side of that distribution.

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 20 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.Current forecasts for São Paulo indicate a minimum temperature near 18–20 °C on September 20, with high uncertainty arising from persistent cloud cover, scattered rain, and variable northerly winds that limit radiative cooling overnight.
