Official Environment Canada forecasts for Toronto on August 8 project a daytime high near 27°C under partly cloudy skies with a 60% chance of showers, reflecting modest southwesterly flow and limited heating. Trader consensus clustering on 29–30°C outcomes arises from model uncertainty around precipitation timing and cloud cover, which can either suppress maximum temperatures through reduced insolation or allow brief clearing that boosts readings by 1–3°C above guidance. Lake Ontario’s moderating influence and typical August humidity levels further narrow the plausible range, while historical analogs for early August show highs averaging 26–28°C under similar patterns. Upcoming model updates from regional ensembles will likely refine these probabilities 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 8 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.
