KPWM by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued no ground stop or ground delay program for PWM in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from PWM's own airspace.
KPWM reported VFR in 79% of daylight observations over 20 years, about 270 flyable days a year. August is the most reliable month and June the least, with IFR or worse 17% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 11% of hours) and low visibility (under 3 miles 8%).
Over 20 years of hourly winds, runway 29 had the best headwind 31% of the time, runway 36 29%, and winds were calm 18% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 41 days a year and freezing rain or drizzle on 5. From December to February KPWM was IFR or worse 14% of the time, against 14% from June to August.
PWM departures left within 15 minutes of schedule 81% of the time across 10,887 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (71%).
Fog was reported on about 54 days a year, and fog or mist on 150. June and December are the foggiest months, with fog in 16% of hours, against 11% in August.

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
