Official forecasts from Environment Canada project a high of 24°C for Toronto on September 9 amid showers and possible thunderstorms, driven by a moist southwesterly flow and increased cloud cover that limits solar heating. Model consensus points to afternoon peaks near 23–25°C depending on the exact timing and intensity of precipitation, with dew points in the upper teens supporting humid conditions. Historical September averages near 23°C provide context, while recent model runs show minor variations in maximum temperature tied to storm evolution. Trader sentiment clusters around 24–26°C because small shifts in forecast details could push the daily high across resolution thresholds, with updated agency briefings expected to refine probabilities ahead of the date.

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 9 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 project a high of 24°C for Toronto on September 9 amid showers and possible thunderstorms, driven by a moist southwesterly flow and increased cloud cover that limits solar heating.
