**Official forecasts from Environment Canada and supporting models indicate a maximum temperature of 15–17°C for Toronto on September 21, 2026, aligning closely with market-implied odds favoring 16°C.** A mix of sun and cloud under northeasterly flow, with surface winds of 15–25 km/h and dew points near 6°C, has limited daytime heating despite moderate insolation. Persistent cloud cover and a cooler air mass have kept readings below the late-September climatological average of roughly 19°C. Hourly observations show temperatures rising from morning lows near 10°C to afternoon peaks around 15–16°C at Pearson Airport, consistent with model consensus. Traders appear to weight these verified conditions and the narrow uncertainty range in short-range guidance, as resolution depends on the official daily maximum recorded at the primary station.

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.**Official forecasts from Environment Canada and supporting models indicate a maximum temperature of 15–17°C for Toronto on September 21, 2026, aligning closely with market-implied odds favoring 16°C.** A mix of sun and cloud under northeasterly flow, with surface winds of 15–25 km/h and dew points near 6°C, has limited daytime heating despite moderate insolation.
