Recent forecasts from global and regional models indicate a highest temperature in São Paulo on August 26 most likely between 21°C and 23°C, aligning with trader consensus on those outcomes. A passing cold front and increasing cloud cover with late showers are expected to moderate daytime heating, while light southeasterly flow limits advection of warmer air. Climatological normals for late August place the average high near 21–22°C, providing context for why probabilities cluster tightly around these values rather than extremes. Key variables differentiating the leading bins include model spread on exact frontal timing and boundary-layer moisture, which official updates from CPTEC and INMET over the next 24 hours will clarify before resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
