Forecast models indicate Sao Paulo's maximum temperature on September 20 will likely peak near 22–24°C amid persistent cloud cover, elevated humidity near 70–90%, and a 30–70% chance of light rain or thunderstorms, which limit daytime solar heating and promote evaporative cooling. Northerly winds of 5–15 km/h add modest mixing without strong advection of warmer air masses. These conditions align with early spring climatology for the region, where average September highs hover around 23°C but can dip lower under overcast skies. Trader consensus reflects model agreement on subdued warming, tempered by uncertainty over exact timing of any afternoon clearing or shower intensity that could shift the daily peak by 1–2°C. Updated observations from official monitoring will refine resolution criteria near market close.

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.
