Official forecasts from Environment Canada position a 25°C high as the leading outcome for Toronto on September 8, with mainly sunny skies transitioning to a mix of sun and cloud, light southerly winds, and negligible precipitation risk. This aligns with multiple numerical weather models showing afternoon maxima clustered between 23–26°C under stable high pressure, slightly above the 1991–2020 climatological average of 23.5°C for the date. Trader consensus reflected in the 43% implied probability for 25°C and 30% for 24°C captures the narrow forecast envelope, while lower odds for 26°C or below account for potential model spread or localized cooling. Updated model runs and official briefings tomorrow morning represent the key data points before evening observations finalize the daily maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 8 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 position a 25°C high as the leading outcome for Toronto on September 8, with mainly sunny skies transitioning to a mix of sun and cloud, light southerly winds, and negligible precipitation risk.
