KARR by the numbers

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

74%

of daylight hours VFR, 2006 to 2025

KARR reported VFR in 74% of daylight observations over 20 years, about 240 flyable days a year. July is the most reliable month and December the least, with IFR or worse 19% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 6% of hours) and low visibility (under 3 miles 6%).

25%

of windy hours favor runway 27

Over 20 years of hourly winds, runway 27 had the best headwind 25% of the time, runway 18 20%, and winds were calm 13% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.

snow days a year

Snow fell on about 40 days a year and freezing rain or drizzle on 5. From December to February KARR was IFR or worse 18% of the time, against 5% from June to August.

thunderstorm days a year

Thunderstorms were reported on about 43 days a year. 54% of storm hours fall in June, July and August, peaking in July when storms were in the air 2% of the time.

2,215 ft

typical summer-afternoon density altitude

Field elevation is 712 ft, but on a median summer afternoon the air performs like 2,215 ft, 1,503 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

13%

of hours with gusts

Gusts showed up in 13% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 69 kt. April is the windiest month (mean 10 kt) and August 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.
