Recent ensemble forecasts from the Global Forecast System and Global Environmental Multiscale models show a tight spread for Toronto’s May 18 maximum, centering on 28–30 °C at Pearson Airport. This narrow range arises because daytime radiative heating under partly cloudy skies is offset by modest southwesterly flow and potential late-afternoon convective clouds that limit surface insolation. Dew-point values near 12 °C and boundary-layer mixing keep the heat budget sensitive to even small changes in cloud timing or thickness, producing the observed market clustering between 28 °C and 30 °C. Updated short-range guidance and hourly observations over the next 48 hours will be the decisive inputs for final 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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Recent ensemble forecasts from the Global Forecast System and Global Environmental Multiscale models show a tight spread for Toronto’s May 18 maximum, centering on 28–30 °C at Pearson Airport.
