Recent forecasts from multiple models indicate widespread rain and thunderstorms across São Paulo on September 22, driven by a passing frontal system that will increase cloud cover and reduce solar heating. This setup favors daytime highs in the low to mid-20s°C, aligning with the market's strong 86% implied probability for 24°C or below. Historical September averages near 23°C provide context, but the expected precipitation—potentially exceeding 10 mm in some runs—further limits warming compared to clearer days earlier in the month. Updated model guidance through the weekend will be key, as any eastward shift in the rain shield could allow brief breaks of sun and slightly higher readings near 26–27°C.

The resolution source for this market will be information from NOAA, specifically the highest 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.
