Current forecast models from sources including the National Meteorological Service equivalents and global ensembles indicate persistent cloud cover, light showers, and northerly winds across São Paulo on September 20, suppressing peak temperatures into the low-to-mid 20s Celsius. This aligns with trader consensus favoring 21–23°C outcomes, as reduced insolation and evaporative cooling from precipitation limit daytime heating below September climatological averages near 23–24°C. Minor model differences in cloud thickness, shower timing, and boundary-layer mixing explain the spread across adjacent bins, with higher probabilities on cooler thresholds reflecting recent cooler-than-normal conditions and ongoing overcast patterns that could shave several degrees from maximums if sustained through afternoon hours.

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.
