Recent forecast models from sources like the National Meteorological Service and global ensembles point to a minimum temperature in São Paulo on August 27 near 16–18°C under clearing skies, light northerly flow, and high pressure, following several cooler days with recorded lows around 13°C earlier in the month. This setup aligns with climatological norms for late austral winter at the city's elevation, where radiative cooling overnight typically produces the daily minimum just before dawn. Trader emphasis on 10°C or below reflects residual uncertainty from model spread and recent variability, while probabilities clustered around 15–16°C capture the consensus trajectory ahead of final observational data.

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 27 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.Recent forecast models from sources like the National Meteorological Service and global ensembles point to a minimum temperature in São Paulo on August 27 near 16–18°C under clearing skies, light northerly flow, and high pressure, following several cooler days with recorded lows around 13°C earlier in the month.
