Forecast models from sources including Environment Canada and GFS consensus show a high near 20–21°C for Toronto on September 20, driven by persistent northeasterly flow advecting cooler maritime air and widespread cloud cover with a 30–40% chance of light showers that limit solar heating. This aligns with the seasonal decline in temperatures, where the 1991–2020 climatological average high stands at 21°C. Recent days featured similar easterly winds and overcast conditions that capped readings below seasonal norms, creating tight market-implied odds between 19°C and 21°C. Official resolution will rely on the highest hourly or daily maximum recorded at Pearson International Airport or downtown stations, with final data releases expected shortly after sunset on the 20th.

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 20 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.Forecast models from sources including Environment Canada and GFS consensus show a high near 20–21°C for Toronto on September 20, driven by persistent northeasterly flow advecting cooler maritime air and widespread cloud cover with a 30–40% chance of light showers that limit solar heating.
