Official Environment Canada observations from Toronto Pearson International Airport confirm the highest temperature on May 13, 2026, reached 16°C around mid-morning under mostly cloudy skies with scattered showers, driving trader consensus to 100% on this outcome. This aligns with pre-event forecast model runs from the Canadian Meteorological Centre projecting limited warming due to a cool upper-level trough and onshore flow suppressing highs below seasonal norms of 18–20°C. Hourly data from the station's automated sensors provide the verifiable evidence, with temperatures peaking at 16°C before stabilizing lower amid 60% precipitation chances. Rare challenges could arise from data quality revisions—such as sensor calibration adjustments—but public past-24-hour reports render resolution effectively final.
