KPTN by the numbers
What the long-run records say about flying here, computed for this airport alone.
KPTN reported VFR in 80% of daylight observations over 20 years, about 239 flyable days a year. July is the most reliable month and February the least, with IFR or worse 21% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 8% of hours, visibility under 3 miles 4%).
Over 20 years of hourly winds, runway 06 had the best headwind 61% of the time, runway 24 39%, and winds were calm 24% of hours. Winds most often blow from the north. Crosswind on the best available runway topped 15 kt in 1% of hours.
Thunderstorms were reported on about 90 days a year. 57% of storm hours fall in June, July and August, peaking in July when storms were in the air 5% of the time.
Fog was reported on about 29 days a year, and fog or mist on 82. February and December are the foggiest months, with fog in 5% of hours, against 1% in July.
Field elevation is 8 ft, but on a median summer afternoon the air performs like 1,782 ft, 1,774 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Winds were calm 21% of the time and averaged 5.7 kt overall. February is the windiest month (mean 7 kt) and July the calmest.
