Recent official forecasts from Environment Canada and supporting models indicate a mostly cloudy day with a 60% chance of showers for Toronto on August 19, supporting clustered market-implied odds around 23–29°C. Cloud cover and precipitation timing limit surface heating by reducing incoming solar radiation, while the prevailing air mass and light winds keep values near the late-summer climatological mean of roughly 24–25°C. Model spread arises mainly from uncertainty in shower onset and duration, which can suppress the daily maximum by several degrees if they arrive before peak insolation. Stronger consensus on avoiding extreme heat or unseasonable cool air keeps probabilities low outside the central range, with traders weighing the latest model runs and satellite trends ahead of the observation window.

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 19 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.
