Clear skies and light winds overnight on August 21 enabled strong radiative cooling, driving Toronto's minimum to 15°C at Pearson Airport—precisely the market's leading outcome. Ensemble forecasts from global models converged on this value after a cooler air mass settled over southern Ontario, with 5 a.m. readings near 59°F (15°C) and daytime recovery to 25°C. Historical August lows average near 17°C, making the dip notable yet within seasonal variability. Traders priced 13–15°C bins highest as model consensus tightened, while sub-12°C or above-16°C scenarios carried minimal probability absent major forecast shifts.

This market will resolve based on the lowest 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 lowest temperature recorded at the Toronto Pearson Intl Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
