Recent forecast models from Environment Canada and NOAA consensus point to overnight lows of 14–16°C in Toronto on August 23 under westerly flow, cloud cover, and scattered showers that limit radiational cooling. This setup, following a frontal passage, keeps surface temperatures above the seasonal 17.1°C average low while preventing deeper cooling that could reach 10°C or below. Trader balance between the 20°C+ and sub-10°C outcomes, alongside clustered mid-teens probabilities, reflects uncertainty in the precise timing of the daily minimum and potential model spread in boundary-layer moisture and wind speed. Updated NHC-adjacent guidance and station observations near dawn will likely refine these odds 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 23 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
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 forecast models from Environment Canada and NOAA consensus point to overnight lows of 14–16°C in Toronto on August 23 under westerly flow, cloud cover, and scattered showers that limit radiational cooling.
