Recent forecast model runs for São Paulo on September 21 indicate a minimum temperature near 19–22°C, driven by northerly flow and limited overnight radiative cooling under partly cloudy skies. An approaching cold front is expected to increase wind speeds and moisture, moderating temperature drops compared to clearer conditions, while historical September averages hover around 12–16°C lows. Trader sentiment splits closely between sub-17°C and above-25°C outcomes due to model divergence on frontal timing and cloud cover, with official guidance from meteorological agencies highlighting uncertainty in exact overnight minima before resolution.

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.
