Current Environment Canada guidance for Toronto on August 10 points to a high near 29°C under cloudy skies with a 60% chance of showers, limiting solar heating and keeping values close to early-August climatological norms of 25–28°C. Recent long-range outlooks, including the Old Farmer’s Almanac, indicate generally sunny conditions for the Aug. 10–16 window but cooler temperatures in eastern Ontario, supporting the market’s tight clustering around 27–29°C. Model consensus and seasonal baselines explain why higher outcomes above 30°C remain low-probability while cooler readings stay in play pending final observations.
