KHEF by the numbers

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

84%

of daylight hours VFR, 2006 to 2025

KHEF reported VFR in 84% of daylight observations over 20 years, about 271 flyable days a year. July is the most reliable month and September the least, with IFR or worse 9% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 7% of hours, visibility under 3 miles 4%).

53%

of windy hours favor 34L, 34R

Over 20 years of hourly winds, the northwest-facing ends (34L, 34R) had the best headwind 53% of the time, the southeast-facing ends (16L, 16R) 47%, and winds were calm 35% of hours. Winds most often blow from the north. Crosswind on the best available runway topped 15 kt in under 1% of hours.

thunderstorm days a year

Thunderstorms were reported on about 34 days a year. 67% of storm hours fall in June, July and August, peaking in June when storms were in the air 2% of the time.

fog days a year

Fog was reported on about 21 days a year, and fog or mist on 79. February and December are the foggiest months, with fog in 6% of hours, against 2% in July.

1,840 ft

typical summer-afternoon density altitude

Field elevation is 192 ft, but on a median summer afternoon the air performs like 1,840 ft, 1,648 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 68 kt. March is the windiest month (mean 7 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.
