Official forecasts from Environment Canada and GFS-based models indicate a minimum temperature of 12–13°C for Toronto on September 11 under clear skies and light northwest winds shifting southerly overnight. Radiational cooling will dominate with minimal cloud cover and calm conditions limiting turbulent mixing, allowing surface temperatures to drop efficiently after sunset on September 10. This setup produces values slightly below the late-summer climatological average low near 14–15°C. Model consensus clusters tightly around 12–13°C, yet small differences in boundary-layer humidity, wind speed, and exact timing of clearing create the narrow spread reflected in closely matched market-implied odds for 11°C, 12°C, and 13°C outcomes. Updated model runs and official briefings ahead of the overnight period remain the key variables for traders.

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.
