Current forecasts from Environment Canada and other models indicate a high near 24–25°C for Toronto on August 25, driven by a mix of sun and cloud with limited warming from onshore flow and possible afternoon showers. This consensus, backed by recent model runs showing modest diurnal heating under partly cloudy skies, positions 24°C as the market leader at 51.5% implied probability while supporting 25°C at 29%. Historical August averages around 24–26°C and the absence of strong high-pressure ridging or clear skies reduce upside potential, though any last-minute shift in steering patterns or reduced cloud cover could elevate readings toward 26°C. Traders are closely monitoring updated NHC-adjacent guidance and local observations ahead of tomorrow’s resolution.
