Recent forecast model consensus, including GFS runs, indicates a high near 20–21°C for Toronto on September 18 under northerly flow at 8–10 mph, with mostly cloudy skies limiting daytime heating and no significant warm advection. This aligns with the long-term September 18 average of 21.4°C while falling short of warmer analogs, as increasing high cloud cover and stable high pressure suppress further warming. Trader odds clustering tightly on 21°C and 22°C reflect ensemble spread in peak timing and local measurement variability, with lower probabilities assigned to 23°C or above given the cool air mass in place. Updated model guidance and official Environment Canada briefings remain the key near-term catalysts.

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 18 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.Recent forecast model consensus, including GFS runs, indicates a high near 20–21°C for Toronto on September 18 under northerly flow at 8–10 mph, with mostly cloudy skies limiting daytime heating and no significant warm advection.
