Current forecasts for Toronto on September 23 point to a daily minimum near 9–11°C, driven by a stable high-pressure ridge promoting partly cloudy skies and light to moderate northeasterly winds that limit mixing while allowing moderate radiational cooling overnight. Model consensus from sources like Environment Canada and global ensembles shows daytime highs of 17–19°C under easterly flow, with overnight lows tempered by dew points around 6–9°C and minimal precipitation. Trader sentiment splits near-evenly between sub-5°C and 15°C+ outcomes because small variations in cloud cover or wind could shift the minimum by several degrees; historical September climatology places typical lows near 10–12°C, underscoring the narrow window for resolution. Updated model runs and official briefings tonight will likely refine these probabilities before the market closes.

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.
