KGGI by the numbers
What the long-run records say about flying here, computed for this airport alone.
KGGI reported VFR in 80% of daylight observations over 20 years, about 258 flyable days a year. July is the most reliable month and December the least, with IFR or worse 18% 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 5%).
Over 20 years of hourly winds, runway 13 had the best headwind 53% of the time, runway 31 47%, and winds were calm 11% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 2% of hours.
Snow fell on about 51 days a year. From December to February KGGI was IFR or worse 16% of the time, against 4% from June to August.
Fog was reported on about 28 days a year, and fog or mist on 91. January and December are the foggiest months, with fog in 9% of hours, against 2% in June.
Field elevation is 1,008 ft, but on a median summer afternoon the air performs like 2,627 ft, 1,619 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Gusts showed up in 19% of hours, typically 6 kt above the steady wind, and the strongest credible gust on record was 59 kt. April is the windiest month (mean 10 kt) and August the calmest.
