Current forecasts from Environment Canada and numerical models indicate Toronto's daily minimum on September 8 will likely fall near 16–18 °C under partly to mostly cloudy skies, with a chance of showers and light easterly winds limiting overnight radiative cooling. Dew points near 14 °C and stable high pressure support modest temperature drops rather than sharp nocturnal declines typical of clearer conditions. Historical September averages place the normal low around 15 °C, so the market's tight spread—led by the 15 °C outcome—reflects model uncertainty in exact timing of any showers and cloud cover. Fresh GFS and regional runs later today could shift implied probabilities if they revise the overnight low.

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 8 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 forecasts from Environment Canada and numerical models indicate Toronto's daily minimum on September 8 will likely fall near 16–18 °C under partly to mostly cloudy skies, with a chance of showers and light easterly winds limiting overnight radiative cooling.
