PASM by the numbers

What the long-run records say about flying here, computed for this airport alone.

59%
of daylight hours VFR, 2006 to 2025

PASM reported VFR in 59% of daylight observations over 20 years, about 152 flyable days a year. May is the most reliable month and July the least, with IFR or worse 28% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 19% of hours, visibility under 3 miles 9%).

35%
of windy hours favor runway 07

Over 20 years of hourly winds, runway 07 had the best headwind 35% of the time, runway 35 30%, and winds were calm 8% of hours. Winds most often blow from the east. Crosswind on the best available runway topped 15 kt in 1% of hours.

67
snow days a year

Snow fell on about 67 days a year. From December to February PASM was IFR or worse 20% of the time, against 24% from June to August.

43
fog days a year

Fog was reported on about 43 days a year, and fog or mist on 105. February and March are the foggiest months, with fog in 12% of hours, against 3% in June.

23%
of hours with gusts

Gusts showed up in 23% of hours, typically 7 kt above the steady wind, and the strongest credible gust on record was 66 kt. February is the windiest month (mean 12 kt) and July the calmest.

“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.
