Official National Weather Service observations for Denver on September 30 confirmed a daily maximum temperature of 62-63°F, aligning precisely with the market's resolved outcome and driving the 100% consensus. This reading occurred under mostly cloudy skies with light rain, yielding a 9°F departure below the 1991-2020 normal high of 73°F and well below recent historical values. The result reflects typical early-autumn cooling patterns in the Front Range, where persistent cloud cover and modest precipitation suppressed daytime warming. While final climatological reports carry minor revision risk from quality-control checks or station-specific adjustments, the preliminary data from the Denver/Boulder NWS office leave little realistic room for shifts outside this narrow range.
