Frequently asked questions
What runways are available at KSBM?
Sheboygan County Memorial International Airport has two paved runways. Runway 04/22 is concrete, measuring 6,801 feet long and 100 feet wide. Runway 13/31 is asphalt, measuring 5,002 feet long and 75 feet wide. The longer runway supports larger business jets, while the crosswind runway adds flexibility in variable wind conditions.

Is customs clearance available at KSBM?
Yes, Sheboygan County Memorial International Airport has onsite CBP inspection services. Customs clearance operates on a prior permission required basis, Monday through Friday, between 1100 and 1900. Aircrews should arrange clearance in advance rather than expecting walk-up service outside those days and hours. This makes KSBM a workable border-crossing point for business aviation traffic arriving from outside the United States, provided the schedule and PPR requirement are respected.
What fuel types does KSBM offer?
Sheboygan County Memorial International Airport stocks both 100LL avgas and Jet A fuel, listed in the data as A+. Fuel is available 24 hours a day using a credit card, which allows self-service access outside staffed hours. The airport is not towered and operates on an attendance schedule of dawn to dusk daily. The combination of round-the-clock fuel access and dual fuel types supports both piston and turbine operators.
How busy is business aviation traffic at KSBM?
Business aviation accounted for 3,654 of the 4,550 total annual operations at Sheboygan County Memorial International Airport in 2025, according to FAA TFMSC data. Traffic is concentrated in the warmer months, peaking at 678 operations in August. Winter months see considerably less activity, with January recording only 111 operations. This seasonal pattern reflects the Wisconsin lakeshore climate, where flying conditions and demand shift substantially between summer and winter.
What wildlife or activity hazards are noted at KSBM?
Sheboygan County Memorial International Airport reports ultralight activity on and in the vicinity of the airport. Waterfowl and deer are also noted on and in the vicinity of the field, which pilots should factor into approach and departure planning. These are standing operational remarks rather than seasonal alerts, so crews operating at KSBM at any time of year should maintain awareness of both wildlife and ultralight traffic near the runway environment.
