Official forecasts from Environment Canada and supporting meteorological models indicate a daily minimum temperature near 11–14°C for Toronto on September 20, driven by persistent easterly to northeasterly flow, increasing cloud cover, and a 30% chance of showers that limit overnight radiative cooling. These conditions align with mid-September climatology for the region, where average lows hover around 11°C, supporting elevated implied probabilities for outcomes at or below 13°C. Trader consensus reflected in the 49% odds for 18°C or higher captures uncertainty around potential model shifts or localized urban heat effects, with fresh data releases from Environment Canada and updated global ensemble runs expected to refine the range ahead of resolution.

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.
