Latest forecast models from Environment Canada and private sources indicate a warm, humid air mass over Toronto on August 26, 2026, with daytime highs most likely reaching 25–26°C amid scattered showers and thunderstorms. This setup, consistent with late-August climatology showing average highs near 24–26°C, positions 25°C as the market favorite at 46% implied probability, followed by 26°C at 28.5%. Cloud cover and precipitation timing introduce modest uncertainty in peak readings, while the absence of stronger high-pressure ridging or cooler advection keeps probabilities for 24°C or below at 21% combined. Updated model runs and official briefings in the next 24 hours will refine these ranges ahead of market resolution.

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.
