**Forecast models and official guidance from Environment Canada point to a daytime high near 19°C under a mix of sun and cloud with easterly winds around 20 km/h, driving the tight clustering of market-implied odds between 17°C and 18°C.** Cloud cover and moderate onshore flow limit daytime warming by reducing insolation and advecting cooler air from the lake, while the urban heat island effect in downtown Toronto could nudge readings slightly higher than rural stations. Historical September 19 averages near 21°C provide context, but current synoptic conditions favor a cooler outcome. Traders appear focused on model consensus and any late-day updates from Environment Canada or NOAA that could refine the exact maximum before resolution.

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.**Forecast models and official guidance from Environment Canada point to a daytime high near 19°C under a mix of sun and cloud with easterly winds around 20 km/h, driving the tight clustering of market-implied odds between 17°C and 18°C.**
