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.
Environment Canada forecasts a high of 23°C for Toronto on August 28 under mainly sunny skies turning partly cloudy, with northwest winds shifting south at 20 km/h and humidex near 25. This aligns with model consensus from recent runs showing limited afternoon heating due to increased cloud cover and cooler air advection, placing 23°C as the modal outcome in trader-implied probabilities. Nearby stations and ensemble guidance support a narrow range around 22–24°C, with historical late-August baselines near 25°C tempered by the current synoptic pattern. Updated briefings through the afternoon will refine peak readings before market resolution.
