Official forecasts from Environment Canada project a high of 24°C for Toronto on August 16 amid cloudy skies and a 70% chance of showers, positioning that outcome and nearby values as market favorites. Regional patterns for August 10–16 favor cooler eastern Ontario temperatures relative to western areas, consistent with the Old Farmer’s Almanac outlook and climatological averages near 25°C. Recent summer heat-wave variability has given way to these moderating conditions, while model consensus on precipitation timing and intensity introduces uncertainty around whether maxima reach 26°C or remain suppressed near 24–25°C.
