Official forecasts from Environment Canada project a high of 27°C for Toronto on August 27 amid mainly cloudy skies, a 40% chance of showers, and a morning thunderstorm risk, with west winds gusting to 40 km/h and humidex values near 32. Model consensus and recent observations, including morning temperatures around 19–20°C rising through the afternoon, support peaks of 25–27°C, consistent with late-August climatology where daily highs average near 25°C. These factors position 26°C and 27°C as leading market outcomes, with traders weighting the balance of forecast guidance, steering patterns, and limited intensification potential over any extreme deviations. Updated model runs and official briefings remain the key near-term catalysts.

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 27 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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 forecasts from Environment Canada project a high of 27°C for Toronto on August 27 amid mainly cloudy skies, a 40% chance of showers, and a morning thunderstorm risk, with west winds gusting to 40 km/h and humidex values near 32.
