Current forecasts from Environment Canada and supporting models indicate a minimum temperature near 18°C for Toronto on September 8, driven by a mix of sun and cloud with a 40% chance of showers overnight that limit radiative cooling. This exceeds the 1991–2020 climatological average low of 15.2°C amid persistent warm advection and light southeasterly flow. Trader-implied odds, clustered across the mid-teens to low-20s with 11°C-or-below leading slightly, reflect remaining uncertainty in shower timing, cloud persistence, and minor model spread before the event resolves. Updated guidance closer to the date will clarify whether the minimum stays elevated or trends cooler.

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 supporting models indicate a minimum temperature near 18°C for Toronto on September 8, driven by a mix of sun and cloud with a 40% chance of showers overnight that limit radiative cooling.
