Stable high-pressure conditions and clear skies across southern Ontario are positioning Toronto's September 11 high near the 23°C historical average, driving the 57% market-implied probability for that exact outcome. Official forecasts from Environment and Climate Change Canada and multiple models project a daytime peak of 21–24°C under sunny conditions with light northwest winds shifting southerly, limiting mixing and keeping temperatures moderate. This aligns with the 28% odds on 24°C and 14% on 22°C, as slight variations in afternoon insolation or wind could shift the maximum within this narrow band. No significant weather systems or temperature anomalies have emerged in recent model runs, reinforcing trader consensus around climatological norms rather than extremes.

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.
