**Latest multi-model consensus from Environment Canada, GFS, ECMWF, and GEM runs points to a September 14 high of 19–21 °C in Toronto, with 20 °C as the most probable outcome.** Northwest winds behind a recent cold front are advecting cooler, drier air (dew points in the single digits Celsius), limiting daytime heating under partly cloudy skies and moderate insolation. This setup follows warmer 24–26 °C readings on September 12–13 and aligns with climatological norms of gradual autumn cooling. Official forecasts show afternoon peaks near 20 °C (66–68 °F) with minimal precipitation risk, supporting the market’s heavy weighting on 19–21 °C outcomes. Any last-minute model shift in boundary-layer mixing or cloud cover could nudge the exact maximum by 1 °C, but current guidance remains stable into the final 24-hour window.

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.
