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 Toronto Pearson Intl Airport Station in degrees Celsius on 21 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 Toronto Pearson Intl Airport Station, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ. 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.
Current official forecasts from Environment Canada and supporting models indicate a sunny day with a maximum temperature near 25°C for Toronto on August 21, aligning with the strong market-implied probability for that outcome. Late-summer conditions feature typical August averages around 24–25°C, with recent guidance showing limited variability from high pressure and modest humidity rather than extreme heat or cooling fronts. The narrow clustering of probabilities around 24–26°C reflects trader assessment of model consensus and low likelihood of significant deviations, while distant higher or lower thresholds remain improbable absent major forecast revisions. Final resolution will hinge on verified observations from official stations.
