Recent official forecasts from Environment Canada and supporting models indicate sunny conditions over Toronto on September 6, with daytime highs centered near 24–25 °C under light easterly flow and minimal cloud cover. This aligns closely with the 1991–2020 climatological average high of 23.8 °C for the date, positioning 23 °C as the market favorite while supporting elevated probabilities for 22 °C and 24 °C. Traders appear to weigh the risk of slight model cooling against the potential for modest warming if high pressure strengthens, with low precipitation chances reducing uncertainty in maximum temperature resolution. Updated model runs and agency briefings over the next 48 hours will likely drive any shifts in these implied probabilities.

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.
