Official forecasts from Environment Canada and ensemble models indicate a 24°C high for Toronto on August 28 under sunny skies following Thursday’s frontal passage, driving the market’s narrow edge for 24°C (37.5%) over 23°C (31%). Northwest winds behind the front, building high pressure, and clear conditions promote efficient daytime heating from morning lows near 10–14°C, while moderate dew points limit humidex amplification. Historical late-August climatology and recent model consensus support this range, with limited spread across runs reducing odds for 25°C or higher. Updated guidance tomorrow morning could refine the exact maximum before 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 28 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 and ensemble models indicate a 24°C high for Toronto on August 28 under sunny skies following Thursday’s frontal passage, driving the market’s narrow edge for 24°C (37.5%) over 23°C (31%).
