Forecasts for São Paulo on August 27, 2026, point to overnight radiative cooling under mostly clear to partly cloudy skies and light northeasterly winds, with dew points near 13–16°C supporting minimums clustered in the mid-teens. The city’s plateau elevation near 800 m and dry winter air mass enhance nocturnal temperature drops compared with coastal areas, while the urban heat island effect and any lingering haze from recent days may limit how far readings fall. Model consensus shows highs reaching 24–27°C midday before rapid evening decline, creating tight differentiation among 13–16°C outcomes. Traders weigh the latest high-resolution runs and station observations against historical August minima around 12°C, with resolution hinging on the precise timing of the daily low.

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.
