Environment Canada observations at Toronto Pearson International Airport confirm the temperature reached 10°C by 5:00 PM EDT on March 29 under mostly cloudy skies with light SSE winds at 13 km/h, solidifying trader consensus on a daytime high of 10°C or higher. This aligns with late-March 28 forecasts projecting mild conditions amid southwest flow and partial insolation, following an exceptionally warm month with record highs above 25°C earlier, far exceeding typical March averages of 5–7°C. Model consensus from official sources showed low uncertainty, driving the market to full implied probability. Realistic challenges—such as unverified data revisions or extreme late-day cooling—are negligible given verified afternoon peaks and remaining daylight. Final daily maximum reports expected soon.
