Official observational data from Environment and Climate Change Canada confirm an 18°C daily high in Toronto on September 19, 2026, aligning with the market's near-certain consensus. Cooler air advection behind a frontal passage kept maximum temperatures well below the seasonal average of 21°C, with mostly cloudy skies limiting daytime warming. This outcome reflects verified station measurements rather than forecasts, as the date has passed. Minor uncertainties could arise from station-specific reporting differences or final data quality checks, though such revisions are rare for routine surface observations.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 19 Sep '26.
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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Official observational data from Environment and Climate Change Canada confirm an 18°C daily high in Toronto on September 19, 2026, aligning with the market's near-certain consensus.
