Official observations from Environment and Climate Change Canada stations in Toronto recorded a daily maximum of 22°C on October 12, 2026, under clear to partly cloudy conditions with light southwesterly winds that limited further warming. Hourly data showed afternoon peaks near 21–22°C, consistent with model guidance and climatological norms for mid-October, where highs average around 15–16°C but can reach the low 20s during brief warm spells. Trader consensus at 100% for the 22°C outcome reflects verified station measurements rather than forecasts, with negligible odds on adjacent values indicating strong alignment across data sources. A post-resolution revision in official records or a shift to an alternate station for market settlement could theoretically alter the outcome, though such adjustments are rare once preliminary data are confirmed.
