Official National Weather Service observations recorded a maximum of 81°F in Denver on October 2, 2026, under sunny skies with light southerly winds and zero precipitation. This value aligns precisely with the market's 80-81°F outcome, which carries 100% implied probability based on the verified daily climatological summary from NWS Denver/Boulder. The reading occurred at 2:07 PM MDT, nine degrees above the 1991-2020 normal high of 72°F, consistent with recent dry, stable high-pressure conditions across the Front Range. Trader consensus reflects this authoritative measurement rather than forecasts, as the event has concluded. Minor revisions to preliminary data remain theoretically possible but improbable given standard quality controls and cross-verification with stations like Denver International Airport.
