KMAO by the numbers

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

80%
of daylight hours VFR, 2006 to 2025

KMAO reported VFR in 80% of daylight observations over 20 years, about 267 flyable days a year. April is the most reliable month and December the least, with IFR or worse 13% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 9% of hours, visibility under 3 miles 3%).

56%
of windy hours favor runway 22

Over 20 years of hourly winds, runway 22 had the best headwind 56% of the time, runway 04 44%, and winds were calm 30% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.

51
thunderstorm days a year

Thunderstorms were reported on about 51 days a year. 64% of storm hours fall in June, July and August, peaking in July when storms were in the air 3% of the time.

38
fog days a year

Fog was reported on about 38 days a year, and fog or mist on 147. August and December are the foggiest months, with fog in 8% of hours, against 4% in April.

1,840 ft
typical summer-afternoon density altitude

Field elevation is 93 ft, but on a median summer afternoon the air performs like 1,840 ft, 1,747 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

11%
of hours with gusts

Gusts showed up in 11% of hours, typically 7 kt above the steady wind, and the strongest credible gust on record was 54 kt. April is the windiest month (mean 6 kt) and August 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.
