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 13 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 latest forecasts, issued midday on May 13, 2026, project a daytime high of 16°C in Toronto amid persistent cloud cover, 40-60% chance of showers, and gusty west winds of 20-40 km/h, closely matching the market's 98% implied probability for this outcome based on observations at Toronto Pearson International Airport. Hourly data show an early peak near 15°C before cooling to 12°C by afternoon, consistent with a cool upper trough suppressing temperatures below climatological May norms of 18-19°C. Realistic challenges include unexpected afternoon clearing for solar heating to 17°C+, though model consensus and current wind patterns make this improbable; monitor evening observations for final resolution.
