Official forecasts from Environment Canada and supporting models indicate a high near 27–28°C in Toronto on August 12 under northwest winds of 20 km/h, sunny periods transitioning to afternoon cloud cover, and a humidex around 33. This positioning stems from stable high-pressure influence and moderate advection that tempers peak heating relative to earlier summer heat waves, while historical August normals near 24–26°C provide context for the slight elevation. Tight probabilities between 27°C and 28°C reflect minor uncertainties in boundary-layer mixing, insolation under variable cloud, and short-range model spread, with traders weighting the most recent guidance showing limited potential for 29°C or higher.

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 12 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.
