Official forecasts from Environment Canada project a clear night following sunny daytime conditions on August 25, supporting a minimum temperature near 14°C in Toronto, consistent with recent model consensus and slightly below the 17°C historical average low for the date. Cooler air advection from the west, following several days of showers and below-normal highs around 20–21°C, has lowered overnight readings, with current guidance showing limited cloud cover and light winds that favor efficient radiative cooling. Trader positioning, with 11°C or below at 48% implied probability alongside elevated interest in the 13–15°C range, reflects ongoing uncertainty in precise boundary-layer temperatures and potential model adjustments ahead of the overnight minimum, though Environment Canada’s resolution criteria align closely with observed trends. Updated briefings and any late shifts in steering flow remain key near-term catalysts.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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 project a clear night following sunny daytime conditions on August 25, supporting a minimum temperature near 14°C in Toronto, consistent with recent model consensus and slightly below the 17°C historical average low for the date.
