**Divergent numerical weather prediction outputs on overnight radiative cooling drive the near-even split between sub-12°C and 21°C+ minimums for São Paulo on September 19.** Recent polar air advection and a passing cold front have produced below-average temperatures and persistent cloud cover through mid-September, suppressing daytime highs while limiting nocturnal heat loss. Forecast models disagree on the speed of high-pressure ridging and associated clearing: clearer skies would enhance longwave radiation loss and favor lower minima near 13–16°C, whereas increased low-level moisture or light winds could trap heat and push the overnight low above 18°C. Local urban effects and elevation variations across the metropolitan area add further spread to station-specific readings used for market resolution. Traders are weighting the balance of GFS, ECMWF, and regional ensembles, with fresh model runs and official INMET updates expected to resolve the uncertainty before the 24-hour observation window closes.

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 19 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.**Divergent numerical weather prediction outputs on overnight radiative cooling drive the near-even split between sub-12°C and 21°C+ minimums for São Paulo on September 19.** Recent polar air advection and a passing cold front have produced below-average temperatures and persistent cloud cover through mid-September, suppressing daytime highs while limiting nocturnal heat loss.
