**Official forecasts from Environment Canada and multiple meteorological services consistently project a daytime high of 23°C for Toronto on August 28, 2026, under mainly sunny skies transitioning to a mix of sun and cloud.** Northwesterly winds shifting southerly, combined with moderate humidity (humidex near 25), are expected to keep the maximum near this level without significant warming or cooling deviations. Early morning observations around 16°C align with typical diurnal rise patterns for late August, supporting the consensus that the peak will fall in the narrow 22–24°C range. Market-implied odds reflect this tight clustering around the official forecast, with 23°C holding the strongest position because traders incorporate the authoritative NHC/NOAA-style guidance and limited model spread. No major atmospheric shifts, such as unexpected frontal passages or enhanced solar heating, have emerged in the latest updates to alter the trajectory.

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 28 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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 multiple meteorological services consistently project a daytime high of 23°C for Toronto on August 28, 2026, under mainly sunny skies transitioning to a mix of sun and cloud.** Northwesterly winds shifting southerly, combined with moderate humidity (humidex near 25), are expected to keep the maximum near this level without significant warming or cooling deviations.
