KALS by the numbers

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

96%
of daylight hours VFR, 2006 to 2025

KALS reported VFR in 96% of daylight observations over 20 years, about 336 flyable days a year. June is the most reliable month and January the least, with IFR or worse 8% 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%).

65%
of windy hours favor runway 20

Over 20 years of hourly winds, runway 20 had the best headwind 65% of the time, runway 02 35%, and winds were calm 26% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 3% of hours.

33
snow days a year

Snow fell on about 33 days a year and freezing rain or drizzle on 0. From December to February KALS was IFR or worse 6% of the time, against 1% from June to August.

42
thunderstorm days a year

Thunderstorms were reported on about 42 days a year. 73% of storm hours fall in June, July and August, peaking in July when storms were in the air 2% of the time.

10,231 ft
typical summer-afternoon density altitude

Field elevation is 7,540 ft, but on a median summer afternoon the air performs like 10,231 ft, 2,691 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

14%
of hours with gusts

Gusts showed up in 14% of hours, typically 9 kt above the steady wind, and the strongest credible gust on record was 70 kt. April is the windiest month (mean 9 kt) and January the calmest.

Sources: hourly observations 2006 to 2025 and the per-runway wind climatology 2006 to 2025. Historical summaries, not a forecast: check the current METAR, TAF and a briefing before flight.

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.
