Official measurements from São Paulo's primary meteorological stations, including INMET data for Mirante de Santana, confirm a daily maximum of 23°C on August 22, 2026, following a cold front that sharply reduced temperatures from prior peaks near 30–33°C. Preceding forecasts from multiple models converged on a 21–23°C range amid increased cloud cover, southerly winds, and modest precipitation chances, aligning trader consensus with observed values rather than higher or lower thresholds. This outcome reflects typical late-winter variability in the region, where polar air incursions routinely cap highs well below August climatological averages near 24–25°C. Only revised station data or reanalysis adjustments could alter resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 22 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Sao Paulo-Guarulhos International Airport Station, available here: https://www.wunderground.com/history/daily/br/guarulhos/SBGR.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
