**Current forecasts from multiple models, including GFS and ECMWF runs, indicate overnight lows in São Paulo on August 28 will likely fall in the 17–22°C range under clear to partly cloudy skies and light northerly winds.** This stems from a persistent warm, dry pattern with no significant cold-air advection or frontal passage until early September. Recent observations show above-average temperatures persisting through late August, with minimal model spread on the exact minimum driven mainly by small differences in cloud cover, boundary-layer mixing, and dew-point depression overnight. Historical climatology places typical late-August minima near 12–14°C, yet the current setup favors milder readings, creating tight market-implied odds across the 10–19°C thresholds as traders weigh residual model uncertainty against the strong consensus for limited radiational cooling. New model updates and initial station reports will be the next key data points.

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 28 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.**Current forecasts from multiple models, including GFS and ECMWF runs, indicate overnight lows in São Paulo on August 28 will likely fall in the 17–22°C range under clear to partly cloudy skies and light northerly winds.** This stems from a persistent warm, dry pattern with no significant cold-air advection or frontal passage until early September.
