Official Environment Canada guidance points to a high of 27°C on August 30 under southwest flow, yet numerical models diverge sharply on cloud thickness and shower timing that cap solar insolation and trigger evaporative cooling. Persistent overcast and 60% precipitation probability after midday limit surface heating, keeping peak readings near 22–24°C across most guidance. This spread—driven by uncertainties in boundary-layer moisture, frontal timing, and shortwave radiative effects—explains the tight clustering of market-implied odds around those central outcomes, with only modest probability assigned to 25°C or higher if breaks in cloud allow greater afternoon warming.

The resolution source for this market will be information from NOAA, specifically the highest 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
