Recent numerical weather prediction ensembles from Environment Canada and the Global Forecast System show a southwesterly flow advecting warmer air into southern Ontario, positioning Toronto’s official high on May 18 near the 29–32 °C threshold under mostly clear skies that enhance surface heating. Slight differences in predicted boundary-layer mixing, afternoon cloud timing, and wind speeds among model members create the narrow spread across the closely matched market outcomes at 31 °C, 30 °C, 32 °C or higher, and 29 °C. Traders are monitoring the next high-resolution model runs and official Environment Canada guidance for any shift in the maximum temperature forecast before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Toronto Pearson Intl Airport Station in degrees Celsius on 18 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
