**Forecast models from Environment Canada and supporting numerical guidance indicate a high of 15–16 °C for Toronto on September 21 under mainly cloudy skies that clear only gradually in the afternoon.** Persistent northeasterly flow at 20 km/h advects cooler, stable maritime air while limiting vertical mixing and solar heating, keeping daytime maxima well below the prior day’s 20–21 °C. Ensemble spreads remain narrow because the synoptic pattern is well-resolved, with only modest differences in the precise timing of afternoon clearing and boundary-layer depth producing the tight 15 °C (42 %) versus 16 °C (38.5 %) contest. Lower-probability 14 °C or 17 °C outcomes would require either greater persistent cloud cover or earlier clearing than current guidance supports. Updated model runs and the official Environment Canada forecast issued Monday morning represent the key near-term catalysts for any shift in trader positioning.

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 21 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.**Forecast models from Environment Canada and supporting numerical guidance indicate a high of 15–16 °C for Toronto on September 21 under mainly cloudy skies that clear only gradually in the afternoon.** Persistent northeasterly flow at 20 km/h advects cooler, stable maritime air while limiting vertical mixing and solar heating, keeping daytime maxima well below the prior day’s 20–21 °C.
