Forecast models from INMET and international centers indicate typical late-winter conditions in São Paulo, with daytime highs centered near 23–25°C under mostly sunny skies and light southerly winds. The seasonal outlook for above-average temperatures across Brazil supports the market's leading outcomes at 24°C (45%) and 23°C (24.5%), reflecting the climatological average high of about 23–25°C for August without strong frontal systems or heat advection expected on the 23rd. Recent model runs show limited spread, with minimal risk of extremes given stable high-pressure influence and dry air masses typical for the period. Updated guidance ahead of resolution will refine exact maxima measured at official stations.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 23 Aug '26.
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
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.Forecast models from INMET and international centers indicate typical late-winter conditions in São Paulo, with daytime highs centered near 23–25°C under mostly sunny skies and light southerly winds.
