Clear skies and northerly winds are expected to drive overnight radiative cooling in Toronto on August 28, with Environment Canada forecasting a low near 10°C under clearing conditions after Thursday showers. Multiple models show highs around 24°C transitioning to light northwest flow that limits mixing and allows surface temperatures to drop, though slight variations in cloud cover or wind speed could raise the minimum into the mid-teens. Trader consensus clustering around 14–16°C reflects this uncertainty in exact radiative loss versus residual moisture or urban heat effects, while the notable share on 10°C or below incorporates potential for stronger cold advection if the high-pressure ridge strengthens faster than expected. Historical late-August baselines near 14–16°C provide context for the close spread among leading outcomes.

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 28 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.Clear skies and northerly winds are expected to drive overnight radiative cooling in Toronto on August 28, with Environment Canada forecasting a low near 10°C under clearing conditions after Thursday showers.
