Current short-term model guidance and official outlooks from Environment and Climate Change Canada point to a daytime high near 25–26 °C for Toronto on August 20 under mostly sunny to partly cloudy skies with limited convective activity. Lake Ontario’s moderating influence, combined with light southwesterly flow and modest humidity, caps peak heating and creates the narrow spread between those two bins. Minor differences in cloud timing or boundary-layer mixing can easily shift the observed maximum by 1 °C, explaining why 25 °C and 26 °C together command over 80 % of market-implied odds while lower or higher outcomes remain marginal. Updated regional model runs and the next Environment Canada forecast discussion will provide the final inputs before 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.
