Official forecasts from Environment Canada point to a sunny high of 27°C in Toronto on August 18, slightly above the mid-August climatological norm of 25–26°C and supporting the market's tight clustering around 27–28°C outcomes. Surface heating under clear skies, combined with light winds and minimal cloud cover, favors temperatures near or modestly above this level, while any afternoon convective development or thicker cloud bands could cap readings at 26°C or lower. Ensemble model guidance shows limited spread but highlights sensitivity to exact boundary-layer moisture and insolation, keeping 28°C a plausible upside if ridging strengthens. These near-normal conditions align with historical patterns where daily maxima rarely deviate sharply without strong synoptic forcing.

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 18 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 point to a sunny high of 27°C in Toronto on August 18, slightly above the mid-August climatological norm of 25–26°C and supporting the market's tight clustering around 27–28°C outcomes.
