Current forecast models from Environment Canada and global ensembles indicate a high near 22–23°C for Toronto on September 15, driven by southerly flow advecting milder air while persistent cloud cover and a 30–50% chance of light rain or showers limit surface heating and solar insolation. This setup keeps the maximum below seasonal potential despite the warmer trajectory, aligning with the market's tight clustering around 22–24°C outcomes. Historical climatology shows a 22.1°C average high for the date, with recent model runs showing minimal spread; any northward shift in the surface low or reduced cloud deck could push readings toward 25°C, while stronger precipitation would cap them nearer 21–22°C. Updated guidance ahead of the event will refine these thresholds.

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.
