Persistent cloud cover and moderate easterly winds under a stable high-pressure regime are capping daytime heating in São Paulo on September 18, keeping maximum temperatures near 21–23 °C according to consensus model runs and official forecasts. Light mist and high relative humidity further suppress the diurnal rise, while the urban heat-island effect introduces minor variability at different measurement sites. With no strong frontal systems or clear-sky advection expected, the narrow spread in market-implied probabilities (21 °C at 29 %, 22 °C at 24.5 %, 23 °C at 20.5 %) reflects genuine uncertainty over exact peak timing and localized warming rather than divergent large-scale drivers. Updated afternoon observations from INMET stations will likely resolve the outcome.

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 18 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.Persistent cloud cover and moderate easterly winds under a stable high-pressure regime are capping daytime heating in São Paulo on September 18, keeping maximum temperatures near 21–23 °C according to consensus model runs and official forecasts.
