Current ensemble forecasts from models including GFS indicate afternoon highs for Toronto on September 16 centered in the 23–25°C range, with partly to mostly cloudy skies, light northerly winds, and limited mixing due to a passing frontal system keeping peaks from exceeding 26°C. These conditions align with the market’s tight clustering around 24°C (30.5%) and 25°C (36.5%), as traders weigh the balance between modest warm advection and cloud-reduced insolation. Historical mid-September averages near 22°C provide context, yet recent model runs show a slight warm bias relative to climatology. Final official updates from Environment Canada and the next model cycle before local sunset remain the key near-term catalysts.

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.
