Official forecasts from Environment Canada and supporting models indicate a high near 27–28°C for Toronto on September 3, with partly cloudy skies and a 30% chance of showers under light westerly winds. This range reflects typical late-summer conditions slightly above the 24°C climatological average, moderated by Lake Ontario and influenced by upstream trough positioning that limits stronger warming or cooling. Trader consensus around these outcomes stems from recent model runs showing minimal day-to-day shifts, though small variations in cloud timing or shower placement could nudge the daily maximum by 1°C. Historical data confirm 27–28°C falls well within normal September variability for the date.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 3 Sep '26.
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.Official forecasts from Environment Canada and supporting models indicate a high near 27–28°C for Toronto on September 3, with partly cloudy skies and a 30% chance of showers under light westerly winds.
