Live weather, delay risk, and flight conditions for Aspen-Pitkin County Airport (ASE)
Aspen's mountain weather changes fast, and conditions at KASE differ sharply from those in Denver or Eagle. The forecast above shows chance of precipitation and snow accumulation for the days ahead, while live current conditions report sky cover from clear to partly sunny, partly cloudy, or overcast. Each of these affects whether E175 jets can safely land or take off.
When current conditions show partly sunny or partly cloudy skies with light wind, flights usually run on time. But rain and snow showers, low cloud ceilings, or strong gusts often trigger delays. Winter storms and summer afternoon thunderstorms are the most common causes.
Even a slight chance of rain at lower elevations can mean heavy snow at the airport, since KASE sits at 7,820 feet. Air traffic into Aspen is more weather-sensitive than at most US airports because of the valley terrain and limited approach paths.
Aspen-Pitkin County Airport (KASE) sits in a steep mountain valley at 7,820 feet. Low clouds, poor visibility, and strong winds force pilots to delay or cancel flights more often than at most US airports.
KASE is the ICAO code for Aspen-Pitkin County Airport. The shorter FAA code is ASE. Both refer to the same airport in Aspen, Colorado.
Snowstorms, rainstorms, and thunderstorms with low visibility, low cloud ceilings, and/or strong winds are the top causes. The airport's mountain location means that the weather can change quickly as well.
The Embraer E175 is the main regional jet that flies into Aspen. Like every commercial plane, it has strict weight, wind, and visibility limits for landing. Aspen's altitude and mountain terrain make these limits become relevant more often.
Check the live weather conditions and KASE forecast above. If visibility, ceiling, or wind are flagged as risky, expect possible delays or cancellations. You can also see today's full schedule on the Aspen flight board.
Morning flights tend to be the most reliable. Afternoon thunderstorms in summer and evening winds in winter are common causes of delays.
