**Recent meteorological forecasts for São Paulo on September 23, 2026, center the daily minimum near 13–14°C amid persistent overcast skies, light rain or drizzle, and southerly to southeasterly winds that limit nocturnal radiative cooling.** Model consensus shows temperatures bottoming out around dawn under high humidity and cloud cover near 100%, suppressing the drop below the seasonal average low of roughly 12–15°C. The near-even market split between 13°C and 14°C captures small differences across ensemble runs in wind mixing and the exact hour of any partial clearing. Lower-probability outcomes below 12°C would require stronger cold-air advection or clearer skies than currently indicated, while warmer readings remain unlikely given the steady moisture and wind pattern. Updated model guidance through the day will refine the final recorded minimum at official stations.

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.
