Recent forecasts from Environment Canada and multiple models indicate Toronto's overnight low on September 7 will likely fall between 13–16 °C under clear skies, light northwest winds, and stable high pressure, aligning with the historical average minimum of 15.4 °C. This consensus supports the tight clustering of market-implied odds around 14 °C and nearby thresholds, while the notable share for 10 °C or below reflects residual uncertainty in model runs, radiational cooling rates, and exact observation timing at Pearson Airport. Warmer outcomes above 18 °C appear discounted given the absence of significant warm advection. Traders are monitoring final model updates and surface observations through the night for any late adjustments.

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 7 Sep '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
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 forecasts from Environment Canada and multiple models indicate Toronto's overnight low on September 7 will likely fall between 13–16 °C under clear skies, light northwest winds, and stable high pressure, aligning with the historical average minimum of 15.4 °C.
