Current forecast guidance for Toronto on September 21 shows a high temperature most likely in the 15–17°C range, driven by northeast winds advecting cooler maritime air and extensive cloud cover that limits daytime heating. Official Environment Canada outlooks call for a mix of sun and cloud with an 18°C high, while several numerical models and private forecasts converge near 16°C or 60°F under overcast skies and light precipitation chances. These conditions follow a cooler weekend pattern, with historical September averages around 20°C providing context for the expected dip. Market-implied odds cluster tightly on 15–16°C because model spreads and timing of any clearing introduce genuine uncertainty ahead of final observational data.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 21 Sep '26.
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.Current forecast guidance for Toronto on September 21 shows a high temperature most likely in the 15–17°C range, driven by northeast winds advecting cooler maritime air and extensive cloud cover that limits daytime heating.
