**Current short-range model consensus and official guidance from Environment Canada point to a high of 18–20 °C for Toronto on September 24 under clear skies and light easterly flow.** Persistent high pressure and northeasterly winds have suppressed daytime warming while keeping overnight lows near 6–9 °C, producing the mild late-September profile now priced into the market. Environment Canada’s latest forecast explicitly calls for sunny conditions and a 20 °C maximum, aligning with the 20 °C outcome at 21.5 % but leaving room for micro-site or timing differences that favor the 19 °C bin (48 %). Historical normals near 20 °C and the absence of any incoming frontal systems reinforce tight clustering around 18–20 °C, with minimal precipitation risk through the period.

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.
