Recent forecasts from Environment Canada and other models indicate a high near 23–24°C for Toronto on September 9 amid a southwest flow, high humidity, and widespread cloud cover with showers and thunderstorm risk that will limit daytime heating. These conditions, combined with Lake Ontario’s moderating influence and the seasonal decline in solar angle, create tight clustering around mid-20s Celsius values, consistent with the historical average high of 23.3°C. Trader emphasis on 25–26°C outcomes reflects uncertainty over exact rainfall timing, potential brief clearing that could allow modest warming, and urban heat-island effects, while lower probabilities for 27°C+ or sub-24°C reflect the low likelihood of significant model shifts or atypical steering patterns before resolution. Official measurements from Pearson Airport will determine the precise peak.

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.
