Recent Environment Canada forecasts for Toronto on August 16 point to a daytime high near 24–26°C under mostly cloudy skies with a 60–70% chance of showers, aligning with the market's strongest implied probabilities for 25–26°C outcomes. Persistent cloud cover and potential convective activity from a passing trough have limited insolation and evaporative cooling, tempering peak readings below the late-summer climatological average of ~25–27°C. Model consensus shows modest variability tied to exact shower timing and wind direction, keeping 27°C or higher at lower odds while rendering extremes above 29°C unlikely without rapid clearing. Updated model runs and official bulletins through the morning will refine these probabilities ahead of 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 16 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.
