Current official forecasts from Environment Canada project a minimum near 18°C overnight into August 26 under cloudy skies with a 30% chance of showers, consistent with late-August climatology where typical lows hover around 15°C. Ensemble guidance from GFS and ECMWF shows modest spread driven by variable cloud cover modulating radiative cooling, boundary-layer winds, and any weak frontal passages that could either enhance or suppress the urban heat island effect. With market-implied odds balanced near 47.5% between sub-9°C and 19°C+ outcomes, traders appear focused on resolution sensitivity to small forecast revisions in dew points or wind speeds ahead of final observations, rather than any singular catalyst like a sharp cold-air intrusion.

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.Current official forecasts from Environment Canada project a minimum near 18°C overnight into August 26 under cloudy skies with a 30% chance of showers, consistent with late-August climatology where typical lows hover around 15°C.
