Airport Overview
Half Moon Bay Airport (KHAF/HAF), also known as Eddie Andreini Sr. Airfield, is a public-use general aviation airport owned and operated by San Mateo County. It sits on the Pacific coast roughly 4 miles north of downtown Half Moon Bay and about 9 nautical miles southwest of San Francisco International. The field is a popular weekend and recreational destination known for its coastal setting and proximity to the town, but it operates as a light-GA reliever rather than a business-jet gateway.
Runway Capability
The single runway, 12/30, is 5,000 by 150 feet of asphalt at 66 feet MSL. That length nominally accommodates light jets in good conditions, but the airport's traffic is overwhelmingly piston aircraft, vintage warbirds, and light turboprops. Charter clients targeting jet service should verify aircraft performance carefully and recognize that many operators will prefer nearby fields with control towers and instrument precision approaches.
Charter Considerations
KHAF is non-towered (CTAF 122.8) with RNAV (GPS) and visual approaches and no ILS. There is no full-service jet FBO; ground handling, fuel, and parking run through San Mateo County airport operations. For most business-jet missions in the San Francisco Bay Area, The Jet Finder can position aircraft at San Carlos (KSQL), Palo Alto (KPAO), Oakland (KOAK), or SFO, then arrange ground transport down the coast — often a better fit than a light jet into Half Moon Bay.
Safety & Planning
The dominant planning factor at Half Moon Bay is coastal weather. The marine layer and fog frequently reduce ceilings and visibility to IFR or below minimums, and without a precision approach or control tower, conditions can close the field to arrivals on short notice. Always file with a realistic alternate, watch the TAF and webcams closely, and build schedule flexibility into any KHAF itinerary.
Customs & International
Half Moon Bay has no on-field U.S. Customs and Border Protection facility, so it cannot serve as a port of entry for international flights. Inbound international charters must clear customs at a designated airport — San Francisco International (KSFO) and Oakland (KOAK) are the nearest options — before continuing to KHAF if the aircraft is suitable for the field.
Regional Context
Half Moon Bay is one of several Bay Area GA fields. Within roughly 20 nautical miles are San Francisco International (KSFO, ~9 NM), San Carlos (KSQL, ~12 NM), Oakland (KOAK, ~18 NM), and Palo Alto (KPAO, ~19 NM). These alternatives offer control towers, longer runways, instrument precision approaches, and established jet FBOs, making them the practical choice for most private-jet travel serving the San Mateo coast and Silicon Valley.
