Official forecasts from Environment Canada and supporting model guidance, including GFS runs, indicate a daytime high near 12–13 °C under persistent cloudy skies and easterly flow on October 15. This aligns with mid-October climatology for Toronto, where the seasonal normal maximum sits around 13 °C, and current observations show temperatures climbing from overnight lows near 7–8 °C to midday values around 12 °C. Light precipitation is expected mainly overnight and will not suppress the daytime peak. Model consensus remains tight, with limited spread supporting the market’s concentration on 12 °C and 13 °C outcomes while assigning low probability to 14 °C or higher.
