Official hourly observations from Environment Canada at Toronto Pearson International Airport—the designated station for this market—confirm the highest temperature on April 18 reached exactly 20°C at 2:00 PM EDT, amid partly cloudy skies, northwest winds around 15-20 km/h, and moderating highs after midday. This precise measurement, captured by automated sensors and standard meteorological protocols, underpins the trader consensus implying 100% probability for 20°C, reflecting the skin-in-the-game wisdom of prediction markets on resolved weather outcomes. While final daily summaries undergo routine quality control within 24-48 hours, realistic challenges would require rare instrument recalibration or data anomaly detection shifting the max beyond 20°C, a scenario with negligible historical precedent at this major airport site.
