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 19 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. 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.
São Paulo’s forecast maximum of 31°C on August 19 under a stable high-pressure system drives the market’s heaviest weighting toward 31°C and 32°C outcomes. Clear skies promote strong solar insolation and daytime heating, while light winds and afternoon humidity dropping below 30% limit evaporative cooling and allow temperatures to peak higher than the August climatological average near 25–27°C. Official guidance from local monitoring agencies reinforces this setup, with subsidence inhibiting cloud formation and supporting rapid surface warming. These conditions create a narrow probability band around the upper 20s to low 30s Celsius, as minor shifts in timing or boundary-layer moisture could nudge the daily high one degree either direction before resolution.
