Current forecasts from Environment Canada, the Met Office, and GFS-based models indicate a high of 16–17 °C for Toronto on October 3 under clearing skies and a building high-pressure ridge, with light easterly flow limiting daytime warming. This consensus aligns with the market’s leading outcomes at 17 °C (48.5 %), 16 °C (23.5 %), and 18 °C (20.5 %), as traders weigh the narrow spread around the climatological early-October mean of 17.9 °C. Recent model runs show minimal spread, with stable steering patterns expected to hold through the short 48-hour window; any modest upward revision would require stronger southerly flow or delayed clearing, while cooler solutions remain possible if boundary-layer mixing stays limited.
