Latest model consensus and official forecasts point to an overnight minimum near 21–22°C in São Paulo under partly cloudy skies and light northerly winds, which limit strong radiative cooling while allowing typical dry-season heat loss. In the region's winter dry pattern, moderate humidity and calm conditions favor these mild lows rather than deeper drops, aligning with current observational trends showing no incoming cold fronts. Market-implied odds concentrate on 20–22°C outcomes as traders weigh stable atmospheric guidance against minor forecast variability ahead of official INMET verification for the calendar day.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 29 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Latest model consensus and official forecasts point to an overnight minimum near 21–22°C in São Paulo under partly cloudy skies and light northerly winds, which limit strong radiative cooling while allowing typical dry-season heat loss.
