Latest model guidance from Environment Canada and global ensembles points to a highest temperature in the mid-20s°C for Toronto on August 19, with trader consensus favoring 25–26°C amid partly cloudy skies and light winds. Lake Ontario moderation, combined with weak high pressure and limited diurnal heating under variable cloud cover, caps daytime peaks near seasonal normals of 24–26°C. Subtle differences among leading outcomes hinge on forecast timing of any afternoon clearing versus isolated thunderstorm development, which could alter maximum readings by 1–2°C. Updated short-range model runs and official Environment Canada briefings over the next 12–24 hours will refine these thresholds 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 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.
