Persistent warm air and elevated overnight humidity from thunderstorm activity kept Toronto's minimum temperature from falling sharply on August 22. Official forecasts from Environment Canada and The Weather Network consistently projected morning readings near 19 °C and nighttime lows of 17–21 °C under cloudy, breezy conditions, well above the late-August climatological normal of roughly 14–16 °C. Model consensus showed limited radiational cooling because of cloud cover and southerly flow, pushing market-implied odds for a lowest temperature of 19 °C or higher to 86.5 %. Cooler outcomes below 17 °C carried low probability because no cold-air intrusion or clear-sky radiative event materialized in the final model runs before the observation window closed.

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.
