Current forecast models from Environment Canada and major ensembles show Toronto's August 20 high stabilizing near 25°C under partly cloudy skies with light southwesterly flow and possible isolated showers, consistent with late-summer climatology moderated by Lake Ontario's thermal inertia. This positions 25–26°C as the market leaders by reflecting limited daytime heating potential amid decreasing solar angles and any convective cloud cover. Recent model runs have shown little shift from seasonal baselines, with no strong warm advection or blocking high expected to push readings to 28°C or above, keeping higher outcomes at low implied probabilities while acknowledging typical forecast uncertainty ranges of ±1–2°C near resolution.

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 20 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 forecast models from Environment Canada and major ensembles show Toronto's August 20 high stabilizing near 25°C under partly cloudy skies with light southwesterly flow and possible isolated showers, consistent with late-summer climatology moderated by Lake Ontario's thermal inertia.
