Latest forecasts from Environment Canada and The Weather Network project a high near 24–26°C in Toronto on August 15 under a mix of sun and cloud, aligning with the market’s leading 24°C outcome at 50% implied probability. Mid-August climatology centers on daily maxima around 25–26°C, and numerical models indicate modest uncertainty tied to variable afternoon cloud cover and weak steering patterns that limit strong ridging or heat advection. This keeps the distribution clustered on 24–28°C bins while assigning low odds to extremes above 29°C or below 22°C. Updated model runs overnight and morning observations will refine the range before 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 15 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.
