Environment Canada’s official forecast for Toronto on August 10 projects a daytime high of 29°C under cloudy skies with a 60% chance of showers, a key driver keeping market-implied odds tightly clustered between 27°C and 29°C. Variable cloud cover and potential convective cooling from precipitation introduce typical ±1–2°C forecast uncertainty, while regional high pressure and steering patterns limit stronger warming. Historical August baselines near 26°C and model consensus on modest instability further support trader focus on these narrow outcomes ahead of the next official update.
