Environment Canada’s official forecast calls for a high of 21°C in Toronto on September 20 under a mix of sun and cloud, with morning showers possible and northerly winds strengthening to 20 km/h, which should limit afternoon warming. Other numerical guidance clusters between 19–20°C amid persistent cloud cover and dry air, aligning with the historical average high of 21°C for the date. Trader positioning, heavily weighted toward 20°C and 21°C, reflects this narrow forecast envelope and the resolution criteria based on official station observations, with limited upside risk for 22°C or higher given the steering pattern and modest insolation. Updated model runs and real-time station data through the afternoon will determine final market resolution.

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.
