KMTN by the numbers

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

81%
of daylight hours VFR, 2006 to 2025

KMTN reported VFR in 81% of daylight observations over 20 years, about 248 flyable days a year. July is the most reliable month and December the least, with IFR or worse 14% 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 runway 33

Over 20 years of hourly winds, runway 33 had the best headwind 53% of the time, runway 15 48%, and winds were calm 32% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in 1% of hours.

31
thunderstorm days a year

Thunderstorms were reported on about 31 days a year. 66% of storm hours fall in June, July and August, peaking in July when storms were in the air 1% of the time.

14
snow days a year

Snow fell on about 14 days a year and freezing rain or drizzle on 1. From December to February KMTN was IFR or worse 12% of the time, against 4% from June to August.

1,553 ft
typical summer-afternoon density altitude

Field elevation is 22 ft, but on a median summer afternoon the air performs like 1,553 ft, 1,531 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

13%
of hours with gusts

Gusts showed up in 13% 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 September 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.
