KAAT by the numbers
What the long-run records say about flying here, computed for this airport alone.
KAAT reported VFR in 91% of daylight observations over 20 years, about 307 flyable days a year. July is the most reliable month and December the least, with IFR or worse 6% of the time. When conditions drop it is usually fog and low visibility rather than low ceilings (visibility under 3 miles 2% of hours, ceilings under 1,000 ft 1%).
Over 20 years of hourly winds, runway 21 had the best headwind 35% of the time, runway 31 26%, and winds were calm 44% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 47 days a year. From December to February KAAT was IFR or worse 5% of the time, against 1% from June to August.
Fog was reported on about 32 days a year, and fog or mist on 133. January and December are the foggiest months, with fog in 13% of hours, against under 1% in July.
Field elevation is 4,378 ft, but on a median summer afternoon the air performs like 6,976 ft, 2,598 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Gusts showed up in 11% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 56 kt. March is the windiest month (mean 6 kt) and October the calmest.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.

“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.
