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 16 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.
Recent forecasts from sources including timeanddate and AccuWeather indicate Sao Paulo highs near 28–29°C (82–84°F) under scattered clouds and easterly winds, with model runs showing minor spread from variable afternoon heating and urban heat island effects at official stations. Wintertime conditions in the Southern Hemisphere, combined with typical August pressure patterns and limited moisture, support this range above the 25°C seasonal average while capping extreme outliers. Trader consensus clusters tightly on 27–29°C because small differences in cloud timing or wind shifts can alter peak readings by 1–2°C, with resolution depending on the day's official maximum from INMET or equivalent monitoring.
