Latest ensemble forecasts from global models point to a daytime high near 23–24°C in Toronto on September 4 under mostly cloudy skies and light northwesterly flow, limiting surface heating. Persistent cloud cover and modest onshore influence from Lake Ontario are expected to cap peak readings, consistent with early-September climatology around 24°C. Trader consensus favoring 25–26°C reflects residual uncertainty in afternoon clearing timing and potential urban heat-island enhancement downtown versus airport observations. Model spread remains narrow, with limited upside risk above 27°C absent stronger ridging. Updated runs from Environment Canada and NOAA are the next key catalysts before market resolution.

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.
