KOSH by the numbers

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

77%

of daylight hours VFR, 2006 to 2025

KOSH reported VFR in 77% of daylight observations over 20 years, about 246 flyable days a year. July is the most reliable month and December the least, with IFR or worse 17% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 5% of hours) and low visibility (under 3 miles 5%).

21%

of windy hours favor runway 18

Over 20 years of hourly winds, runway 18 had the best headwind 21% of the time, runway 27 20%, and winds were calm 12% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 0% of hours.

snow days a year

Snow fell on about 53 days a year and freezing rain or drizzle on 4. From December to February KOSH was IFR or worse 15% of the time, against 4% from June to August.

thunderstorm days a year

Thunderstorms were reported on about 32 days a year. 59% of storm hours fall in June, July and August, peaking in June when storms were in the air 1% of the time.

17%

of hours with gusts

Gusts showed up in 17% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 59 kt. April is the windiest month (mean 9 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.
