Close contest between the 10°C-or-below and 20°C-or-higher outcomes at roughly 49.5% and 49% each reflects substantial uncertainty in short-range guidance for São Paulo’s overnight minimum on September 14. Forecasters are weighing a possible influx of cooler polar air behind a frontal passage against residual warm advection from the northwest, with global models showing a wide spread in 2-meter temperatures. Historical September minima average near 13–15 °C, so resolution hinges on whether a stronger-than-expected cold surge arrives or whether clear skies and light winds allow greater radiational cooling. Updated runs from the Global Forecast System and European Centre for Medium-Range Weather Forecasts, plus local INMET observations, will likely narrow the range before the market resolves.

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.
