KACV 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 ACV in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from ACV's own airspace.
KACV reported VFR in 60% of daylight observations over 20 years, about 176 flyable days a year. December is the most reliable month and July the least, with IFR or worse 49% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 18% of hours, visibility under 3 miles 11%).
Over 20 years of hourly winds, runway 32 had the best headwind 37% of the time, runway 14 32%, and winds were calm 28% of hours. Winds most often blow from the east. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Fog was reported on about 106 days a year, and fog or mist on 281. July and August are the foggiest months, with fog in 26% of hours, against 13% in April.
ACV departures left within 15 minutes of schedule 82% of the time across 2,098 flights, June 2025 to May 2026. Before 9 AM departures did best (87%) and 6 to 9 PM did worst (74%).
Winds were calm 25% of the time and averaged 4.8 kt overall. March is the windiest month (mean 6 kt) and September 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.
| Runway | Length | Surface | Head / Tail | Crosswind |
|---|---|---|---|---|
| 01 | 4,501 ft | ASP | - | - |
| 14 | 6,046 ft | ASP | - | - |
| 19 | 4,501 ft | ASP | - | - |

“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.
