KALO by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued no ground stop or ground delay program for ALO in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from ALO's own airspace.
KALO reported VFR in 78% of daylight observations over 20 years, about 252 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 4%).
Over 20 years of hourly winds, runway 30 had the best headwind 33% of the time, runway 18 26%, and winds were calm 13% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 40 days a year and freezing rain or drizzle on 4. From December to February KALO was IFR or worse 16% of the time, against 4% from June to August.
Thunderstorms were reported on about 44 days a year. 57% 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 873 ft, but on a median summer afternoon the air performs like 2,462 ft, 1,589 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
