Current pilot readout for KCMH
KCMH is currently VFR with calm winds, visibility 10+ statute miles, and no ceiling reported. The tower TFDM states arrivals on runway 28L and 28R and departures on runway 28L and 28R. Density altitude is approximately 750 ft (field elevation 815 ft). Review the latest TAF below for forecast changes before departure.
KCMH 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 CMH in the 12 months to October 2026. Delays here come from the airlines or from programs at other airports rather than from CMH's own airspace.
KCMH reported VFR in 79% of daylight observations over 20 years, about 257 flyable days a year. August is the most reliable month and January the least, with IFR or worse 11% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 4% of hours) and low visibility (under 3 miles 3%).
Over 20 years of hourly winds, the west-facing ends (28L, 28R) had the best headwind 56% of the time, the east-facing ends (10L, 10R) 44%, and winds were calm 16% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 49 days a year and freezing rain or drizzle on 5. From December to February KCMH was IFR or worse 10% of the time, against 3% from June to August.
CMH departures left within 15 minutes of schedule 80% of the time across 44,692 flights, June 2025 to May 2026. Before 9 AM departures did best (91%) and 6 to 9 PM did worst (67%).
Over the last 30 days of recorded D-ATIS broadcasts, KCMH ran west flow 69% of the time and east flow 23%. Runway 28R was named for arrivals most often (75% of recorded hours), and the configuration changed 28 times.

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 tower TFDM configurationstates; 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.
