Why PHX gets delayed
Phoenix sees instrument weather in roughly one hour in a thousand, so it is easy to assume the FAA leaves it alone. In the 12 months to October 2026 it did not: the FAA ran 46 programs for PHX on 36 days. Monsoon thunderstorms in July and August caused about half. Low clouds caused another fifth, mostly in a run of fall programs in October and November 2025, and controller staffing a fifth as well.
The staffing programs were long, all-day affairs during the federal government shutdown, including a 13 h 4 min program on November 10, 2025. Storm stops are short by comparison, typically about 1 h 14 min.
Written by the ATIS Alerts team from FAA Command Center advisories (October 2025 to October 2026), BTS airline on-time data (June 2025 to May 2026) and 20 years of hourly weather observations. Updated October 2026.
