Official forecasts from Environment Canada and aligned models project a daytime high of 26°C for Toronto on August 29 under a mix of sun and cloud with southwesterly winds gusting near 20–40 km/h. This stems from advection of milder air behind Friday’s cooler northerly flow, combined with partial solar heating that supports temperatures near the late-August climatological average of ~25°C. Trader sentiment splits closely between 26°C and 27°C because models show only marginal differences in peak insolation and boundary-layer mixing, with humidex values near 29 adding uncertainty around exact maximum readings at monitoring sites. No major shifts have emerged in the latest runs to favor one outcome decisively.

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 29 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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 forecasts from Environment Canada and aligned models project a daytime high of 26°C for Toronto on August 29 under a mix of sun and cloud with southwesterly winds gusting near 20–40 km/h.
