Official forecasts from Environment Canada project a high of 27°C for Toronto on September 3 under a mix of sun and cloud with a 30% afternoon shower chance and humidex values near 34, driven by light westerly winds and persistent moisture. Multiple model runs align on this range, with hourly guidance showing afternoon peaks of 26–28°C amid above-average September conditions (historical mean high 24°C). Trader consensus favoring 27–28°C reflects this stable forecast trajectory, though minor model shifts in cloud cover or precipitation timing could nudge the observed maximum by 1°C before evening resolution.

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 project a high of 27°C for Toronto on September 3 under a mix of sun and cloud with a 30% afternoon shower chance and humidex values near 34, driven by light westerly winds and persistent moisture.
