Latest forecasts from Environment Canada project sunny skies and a daytime high near 31°C in Toronto on May 18, anchoring trader consensus around the tightly clustered 29–32°C outcomes that together exceed 60% implied probability. Ensemble model runs show modest spread due to variable daytime heating under clear conditions and light southerly flow, with historical May averages for the Pearson station serving as baseline. Resolution hinges on the official maximum recorded at Toronto Pearson International Airport, where even small shifts in cloud cover or wind could alter peak readings by 1–2°C. Updated model guidance and real-time observations in the final hours before peak heating remain the key variables that could refine these probabilities further.
