Official Environment Canada forecasts indicate a sunny high of 28°C in Toronto on August 18, above the normal seasonal maximum of 25°C, establishing the primary driver behind market-implied probabilities that cluster tightly around 27–28°C. Recent model consensus and surface observations support this range, with limited cloud cover or precipitation expected to moderate peak readings under prevailing high-pressure influence. Short-term forecast uncertainty remains modest given proximity to the event, though minor revisions in afternoon insolation or boundary-layer mixing could shift outcomes by 1°C. Traders appear to discount higher extremes above 29°C or sub-26°C readings based on current guidance, with resolution hinging on official daily maximum measurements.

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 18 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.
