Recent persistent cloud cover, elevated humidity, and scattered showers from multiple cold fronts and Atlantic moisture transport have moderated daytime heating across São Paulo, aligning with the market's tight clustering around 25–27°C. Official and ensemble model guidance shows peak temperatures sensitive to the precise timing of any afternoon clearing versus continued overcast conditions, with southeasterly flow and possible sea-breeze effects limiting insolation. September's unusually high rainfall totals have further suppressed maxima relative to climatological norms, creating genuine forecast spread that explains the near-even odds between the top three outcomes and minimal probability mass above 28°C. Updated model runs and satellite trends through the morning of September 19 will be key resolution drivers.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 19 Sep '26.
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.Recent persistent cloud cover, elevated humidity, and scattered showers from multiple cold fronts and Atlantic moisture transport have moderated daytime heating across São Paulo, aligning with the market's tight clustering around 25–27°C.
