Forecast models from sources including the Met Office, Yr.no, and others indicate Sao Paulo will experience a shift to southerly winds and widespread rain on September 22, 2026, supporting overnight cooling after daytime highs near 22–27°C. This setup favors minimum temperatures in the 13–18°C range, with some runs projecting 13–15°C under stronger advection and others holding near 18°C if moisture and cloud cover limit radiational cooling. The near-even market split between 24°C-or-higher and 14°C-or-below outcomes reflects genuine model divergence on frontal timing and boundary-layer mixing, while the clustering of probabilities around 15–19°C aligns with historical September climatology for the region when similar synoptic patterns occur. Updated model runs and official observations on the day will resolve the key variables of wind direction and precipitation intensity.

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.
