Recent forecast model consensus from agencies like the Met Office and local sources points to overnight lows in São Paulo around 15–22°C on August 28 under mostly clear skies and light northerly winds, driven by a strong subtropical high promoting radiative cooling but limited by urban heat retention and seasonal warming. Differentiating outcomes hinge on variables like exact minimum timing before sunrise, dew point depression affecting frost risk below 10°C, and any late-model revisions from increased cloud cover or wind that could raise the floor toward 19–20°C. Historical August averages near 12°C provide context, yet current high-pressure dominance and dry conditions support trader emphasis on mild thresholds amid model spread. Updated runs overnight will refine resolution criteria around precise hourly observations.

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.
