Official Environment Canada forecasts for Toronto on August 29 project a sunny day with a high of 26°C, supported by northwesterly flow transitioning to southerly winds and minimal cloud cover. This aligns with climatological norms near 25°C for late August but leaves room for afternoon variability. Trader sentiment, favoring 27°C at 38.5% implied probability ahead of 26°C, reflects model consensus around modest warming potential from clear conditions and surface heating, tempered by uncertainty in exact peak readings. Upcoming Environment Canada updates and real-time observations will refine these probabilities ahead of market 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 29 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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 Environment Canada forecasts for Toronto on August 29 project a sunny day with a high of 26°C, supported by northwesterly flow transitioning to southerly winds and minimal cloud cover.
