Current forecasts from Environment Canada and numerical models indicate a sunny to partly cloudy pattern over Toronto on August 21, 2026, supporting daytime highs centered near 28 °C under moderate southwesterly flow. Differentiation among the closely matched 24–30 °C market outcomes hinges on small variations in boundary-layer moisture, Lake Ontario lake-breeze timing, and any late-day convective cloud cover that could cap peak insolation. Warmer realizations would require stronger subsidence and reduced mixing, while cooler outcomes depend on earlier marine air intrusion or increased cloudiness. Historical August climatology places Toronto’s mean daily maximum near 25–26 °C, so the tight market clustering reflects both the narrow forecast spread and traders’ recognition that final observed highs can shift several degrees with minor changes in steering flow or diurnal heating efficiency.

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 21 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.Current forecasts from Environment Canada and numerical models indicate a sunny to partly cloudy pattern over Toronto on August 21, 2026, supporting daytime highs centered near 28 °C under moderate southwesterly flow.
