Recent forecasts from Environment Canada and numerical models indicate overnight lows for Toronto on August 27 primarily in the 14–19°C range, driven by a passing trough with scattered showers, shifting winds from southwest to northwest, and moderate humidity that limits radiative cooling. Environment Canada projects a daytime high near 27°C with a 30–40% shower chance, followed by a night low around 14°C under increasing clouds, while other guidance (including hourly model outputs) shows stabilization near 17–19°C due to lingering warmth and lighter winds. These conditions align with late-August climatology, where Toronto’s typical daily minimum hovers near 16°C; the market’s heavy weighting toward 17–19°C (over 90% combined implied probability for the top three outcomes) reflects trader consensus on model agreement for modest cooling without a strong cold-air advection event. Updated runs and official briefings through the morning of the 27th will likely refine the exact minimum before resolution.

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 27 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.Recent forecasts from Environment Canada and numerical models indicate overnight lows for Toronto on August 27 primarily in the 14–19°C range, driven by a passing trough with scattered showers, shifting winds from southwest to northwest, and moderate humidity that limits radiative cooling.
