**Official meteorological observations from Toronto-area stations, including Pearson International Airport, recorded an overnight low of 15°C on August 26, 2026, establishing the daily minimum.** Multiple sources, including real-time historical archives and station data, consistently show temperatures bottoming at this level around 5 a.m. before rising through the day to a high near 24°C under partly cloudy conditions with light winds. This aligns with typical late-August climatology for the region, where average lows hover near 17°C but can dip lower under clear, calm nights. Trader consensus at 100% for the 15°C outcome reflects verified station measurements rather than forecasts, with negligible probability assigned to other bins due to the absence of any credible data supporting deviations. Minor station-to-station variations or post-processing revisions remain the only realistic factors that could alter resolution, though current records show strong agreement on the 15°C threshold.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 26 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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 meteorological observations from Toronto-area stations, including Pearson International Airport, recorded an overnight low of 15°C on August 26, 2026, establishing the daily minimum.** Multiple sources, including real-time historical archives and station data, consistently show temperatures bottoming at this level around 5 a.m. before rising through the day to a high near 24°C under partly cloudy conditions with light winds.
