Official forecasts from Environment Canada project a sunny high near 25–26°C for Toronto on August 15, with models showing modest daytime heating under stable high pressure. Slight differences in predicted maximum temperatures hinge on variables such as boundary-layer mixing, urban heat retention, and minor variations in afternoon dew points or light winds. Trader consensus clusters tightly around these values because ensemble guidance exhibits limited spread this close to the event, while historical August climatology centers near 25°C. Any last-minute shifts in observed cloud cover or advection could tip the recorded peak between the two leading outcomes.

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 15 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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Official forecasts from Environment Canada project a sunny high near 25–26°C for Toronto on August 15, with models showing modest daytime heating under stable high pressure.
