**Recent model consensus points to a minimum temperature near 9–11°C for Toronto on September 21, driven by persistent northeasterly flow advecting cooler maritime air under mostly cloudy skies.** Forecasts from multiple sources, including GFS-based outlooks and Environment Canada guidance, show overnight lows around 9–11°C with daytime highs of 15–18°C, cooler than the 1991–2020 climatological average low of 12.7°C. This setup reflects typical late-September cooling but lacks strong signals for either extreme cold advection or rapid warming. The closely matched market odds on 4°C or below versus 14°C or higher likely reflect residual model spread in boundary-layer cooling rates and wind mixing, with the wisdom of crowds assigning roughly equal weight to downside forecast revisions versus any underestimation of moderation. Updated runs and observational data over the next 48 hours will be key resolution drivers.

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 21 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.**Recent model consensus points to a minimum temperature near 9–11°C for Toronto on September 21, driven by persistent northeasterly flow advecting cooler maritime air under mostly cloudy skies.**
