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 4 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.Environment Canada's observations at Toronto Pearson International Airport, the official station for market resolution, show afternoon temperatures peaking at or above 23°C under partly cloudy skies and a robust southwest wind flow gusting to 56 km/h, driving the market's unanimous 100% implied probability on 23°C or higher. Low humidity around 35% and a dew point of 6°C have supported efficient daytime heating, with readings hitting 22.2°C by 4:00 PM EDT amid clearing conditions following early-morning clouds. This exceeds initial 22°C forecasts issued at 5:44 AM, reflecting stronger-than-expected warm air advection. Realistic challenges would require an abrupt cold frontal passage or persistent overcast skies before sunset around 8:20 PM, though current trends and model consensus make this improbable; final daily maximum data expected post-midnight.
