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 20 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.The market's 100% consensus on a 32°C high for São Paulo on August 20 reflects verified station observations of peak afternoon temperatures reaching that threshold amid clear, dry winter conditions that exceeded the month's typical 22°C average maximum. Warm advection from northern air masses, low humidity, and minimal cloud cover enabled strong daytime heating at urban and airport sites, consistent with recent model runs and real-time data from Brazilian meteorological networks. This outcome aligns with a broader warm anomaly across the region that month. Resolution could face minor challenges from station-specific siting differences, exact timing of the daily maximum, or post-event data revisions by official agencies, though such adjustments remain unlikely given the convergence of multiple reports.
