KGUS by the numbers
What the long-run records say about flying here, computed for this airport alone.
KGUS reported VFR in 77% of daylight observations over 20 years, about 239 flyable days a year. August is the most reliable month and January the least, with IFR or worse 20% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 7% of hours, visibility under 3 miles 3%).
Over 20 years of hourly winds, runway 23 had the best headwind 64% of the time, runway 05 37%, and winds were calm 9% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in 3% of hours.
Snow fell on about 46 days a year and freezing rain or drizzle on 11. From December to February KGUS was IFR or worse 17% of the time, against 4% from June to August.
Thunderstorms were reported on about 43 days a year. 59% of storm hours fall in June, July and August, peaking in June when storms were in the air 2% of the time.
Field elevation is 811 ft, but on a median summer afternoon the air performs like 2,349 ft, 1,538 ft higher. Plan for a longer takeoff roll and a weaker climb from June to 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.
