Official short-term guidance from Environment and Climate Change Canada and supporting numerical models indicate a mostly sunny day on August 21 with daytime heating producing a maximum near 25–26 °C, consistent with late-summer climatology for Toronto. Light winds, modest humidity, and limited convective activity under a stable ridge are expected to cap temperatures in this narrow range rather than allowing stronger warming or cooling. Recent model runs have shown little shift over the past 48 hours, reinforcing trader consensus around these outcomes while leaving modest probability for a 24 °C or 27 °C result if boundary-layer mixing or cloud cover deviates from current projections.

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.Official short-term guidance from Environment and Climate Change Canada and supporting numerical models indicate a mostly sunny day on August 21 with daytime heating producing a maximum near 25–26 °C, consistent with late-summer climatology for Toronto.
