Recent forecasts from Environment Canada and multiple models indicate a cloudy, showery pattern for Toronto on August 30 with southwesterly flow and high humidity sustaining overnight lows near 19°C, driving the tight clustering of market-implied odds around 18–20°C. Persistent cloud cover limits radiative cooling, while mild advection from warmer upstream air masses and elevated dew points prevent drops toward the seasonal average low of 16.4°C. Minor model spreads in timing and intensity of showers introduce the small probability mass at 17°C and below, though current consensus favors the higher end of the range given the lack of a strong cold front. Updated model runs and official briefings ahead of the overnight period remain the key near-term catalysts.

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 30 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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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 multiple models indicate a cloudy, showery pattern for Toronto on August 30 with southwesterly flow and high humidity sustaining overnight lows near 19°C, driving the tight clustering of market-implied odds around 18–20°C.
