Official forecasts from Environment Canada and supporting model guidance indicate a high near 19°C for Toronto on September 19, with afternoon temperatures likely peaking between 17–19°C under increasing cloud cover and easterly flow. This setup follows a cooler air mass, limiting daytime warming below the long-term average of 21°C while suppressing stronger solar heating. Ensemble consistency across sources points to minimal upward revision risk absent unexpected clearing, keeping 17°C and 18°C as the dominant market-implied outcomes with combined probability exceeding 80%. Traders appear to weigh the narrow forecast spread and typical observation uncertainty around the daily maximum when pricing these levels ahead of final surface readings.

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 19 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 and supporting model guidance indicate a high near 19°C for Toronto on September 19, with afternoon temperatures likely peaking between 17–19°C under increasing cloud cover and easterly flow.
