Current pilot readout for KOSU

KOSU is currently VFR with calm winds, visibility 10+ statute miles, and no ceiling reported. Density altitude is approximately 700 ft (field elevation 905 ft). KOSU does not publish a TAF. The nearest TAF station is KCMH, about 10 nm away.

KOSU 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

KOSU reported VFR in 77% of daylight observations over 20 years, about 248 flyable days a year. August is the most reliable month and January the least, with IFR or worse 13% 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 4%).

35%

of windy hours favor runway 23

Over 20 years of hourly winds, runway 23 had the best headwind 35% of the time, the west-facing ends (27L, 27R) 30%, and winds were calm 14% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.

snow days a year

Snow fell on about 41 days a year and freezing rain or drizzle on 4. From December to February KOSU was IFR or worse 13% of the time, against 4% from June to August.

thunderstorm days a year

Thunderstorms were reported on about 41 days a year. 59% of storm hours fall in June, July and August, peaking in July when storms were in the air 2% of the time.

2,505 ft

typical summer-afternoon density altitude

Field elevation is 905 ft, but on a median summer afternoon the air performs like 2,505 ft, 1,600 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

12%

of hours with gusts

Gusts showed up in 12% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 55 kt. January is the windiest month (mean 8 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.
