Persistent showers, thunderstorms, and extensive cloud cover over southern Ontario are suppressing nocturnal radiative cooling in Toronto, anchoring the overnight low near the 17.2 °C climatological average for August 22. Environment Canada guidance and regional model consensus point to a minimum of 16–18 °C, with southeast winds of 10–20 km/h limiting mixing while high humidity (near 90 %) and urban heat retention further moderate temperature drops. Slight differences among leading outcomes hinge on the precise timing and intensity of convective activity, local variations between Pearson Airport and downtown stations, and any late-evening clearing that could allow brief additional cooling. Traders are weighting these near-term observational updates heavily, as resolution occurs once the calendar day ends.

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 22 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.
