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 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 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.
Environment Canada’s latest guidance, backed by numerical weather prediction models, centers trader consensus on a 26 °C high for Toronto on August 19, with a mix of sun and cloud, light northwest winds, and a 60 % chance of showers. These conditions align with late-August climatology, where average daytime maxima hover near 25 °C, while modest ensemble spread keeps 25 °C and 27 °C as plausible secondary outcomes. Limited warm-air advection and potential cloud cover or brief showers constrain upside potential, reflected in the market’s heavy weighting toward the narrow 25–27 °C band and negligible probabilities for extremes. Official observations later today will finalize the daily maximum.
