Official observations from Environment and Climate Change Canada at Toronto Pearson International Airport confirm the highest temperature on March 30, 2026, reached 21°C between 15:00 and 18:00 EDT under partly cloudy skies and westerly winds gusting to 40 km/h, well exceeding the 15°C threshold. This outcome topped pre-event forecasts projecting 16–17°C amid a broader warm March pattern, including records like 17.6°C on March 7 and 26°C on March 1, driven by persistent high-pressure ridging. Trader consensus at 100% implied probability reflects these verified hourly measurements, with resolution pending final daily summary; only an improbable data correction from sensor error could challenge it, given consistent afternoon peaks.
