Recent forecasts from Environment Canada and GFS-based models indicate a warm, humid air mass will dominate Toronto on September 9, with daytime highs near 24–25 °C and overnight lows likely holding between 15–19 °C amid showers and increasing cloud cover. Southerly flow ahead of an approaching frontal system advects milder air while reduced radiational cooling under overcast skies and precipitation limits nocturnal temperature drops, keeping the minimum well above the long-term early-September average of roughly 14 °C. This setup creates genuine uncertainty around the precise low, with model runs differing on the timing and strength of the rain-cooled boundary layer, which explains the near-even market split between sub-15 °C and 24 °C-plus outcomes alongside elevated probabilities for 18–21 °C values. Updated NWS and Environment Canada guidance ahead of the event will be the next key data point for traders.

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.
