Official Environment Canada guidance and supporting ensemble models currently project a Toronto high near 26°C on August 13 under partly sunny skies with a 40% chance of showers, which would limit solar heating and cap the maximum. Trader consensus clustering on 27–28°C (74% combined implied probability) reflects uncertainty around afternoon clearing or localized breaks in cloud cover that could allow brief warming, consistent with typical August variability where daily maxima often range 25–28°C. New model runs and observational updates through the evening of August 12 will refine the steering pattern and precipitation timing ahead of market resolution.

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 13 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.Official Environment Canada guidance and supporting ensemble models currently project a Toronto high near 26°C on August 13 under partly sunny skies with a 40% chance of showers, which would limit solar heating and cap the maximum.
