Latest forecasts from Environment Canada and The Weather Network call for a mainly sunny to partly cloudy day in Toronto on August 20 with a high near 25°C and a 20–40% chance of showers, keeping market-implied odds tightly split between 25°C and 26°C. The narrow gap reflects uncertainty in peak heating: afternoon cloud build-up or scattered convection could limit surface warming by 1–2°C through reduced solar insolation, while clearer breaks would allow temperatures to reach 26°C under typical August boundary-layer conditions. Historical climatology places average highs around 24–25°C, so current model consensus aligns with the leading outcomes while leaving room for small revisions from updated guidance or observed radar trends before resolution.
