Jet noise from MCAS Miramar: which neighborhoods hear it, and what a buyer is told

MCAS Miramar is a working Marine Corps fighter base in the middle of the city, surrounded by neighborhoods that grew up around it. Whether you'll hear it from a given apartment depends mostly on one thing: which way the jets fly.

Which way the jets go

Miramar has two parallel runways, a 12,000-foot one on the north side and an 8,000-foot one on the south. According to the base's 2020 Air Installations Compatible Use Zones (AICUZ) study, both are used "almost exclusively" in the westerly direction. Arrivals come in from the east. Most fighter departures head west through a corridor the base calls Seawolf, out over the neighborhoods northwest of the base to the ocean; a second departure route, Lakee, turns northeast.

Base

1. 1MCAS Miramar runways — Two parallel runways, used westbound

Departure side (north and west)

1. 2Mira Mesa — City planning maps show 65–75 dB contours and an Accident Potential Zone in parts of Mira Mesa
2. 3Sorrento Valley — Under the Seawolf corridor toward the coast
3. 4University City — Named in the AICUZ; site of the 2008 F/A-18D crash

North and east

1. 5Scripps Ranch — North of the base; named in the AICUZ
2. 6Santee — East of the base, on the arrival side

South of the base

1. 7Kearny Mesa — The 65 dB contour stays mostly on base to the south
2. 8Tierrasanta — Named in the AICUZ
3. 9Clairemont — Named in the AICUZ as Clairemont Mesa

How loud, and where

Noise around airfields is mapped as CNEL, a 24-hour average that counts evening and nighttime noise more heavily. The 2020 AICUZ names the affected communities as Mira Mesa, Scripps Ranch and Poway to the north; Clairemont Mesa, Kearny Mesa and Tierrasanta to the south; Sorrento Valley and University City to the northwest and west; and Santee to the east. The update said the louder contours had "contracted somewhat in a few areas" compared with earlier maps.

Averages hide the peaks. Expect the loudest days around America's Air Show, which ran September 25–27 in 2026, when performers rehearse in the days beforehand.

The F-35s

Miramar's F/A-18 Hornets are being replaced by F-35s. The first F-35C arrived in January 2020; squadron VMFA-314 reached initial operating capability that year and VMFA-311 followed on July 31, 2024. The 2020 AICUZ plans for four F-35B and two F-35C squadrons by 2032. You'll often hear that the F-35 is louder. We couldn't find that finding in the environmental documents, so we're not repeating it. Residents did report a distinctive howling sound during F-35C carrier-landing practice in 2020.

What a buyer is told, and a renter isn't

California requires a "Notice of Airport in Vicinity," warning of "noise, vibration, or odors," for property in an airport influence area (Business and Professions Code §11010), and a natural hazard disclosure report must say whether the home is in one (Civil Code §1103.4). In the City of San Diego, the Airport Land Use Compatibility Overlay Zone itself counts as notice of overflight (Municipal Code §132.1525), and new homes in the overflight area carry a recorded notice on title. We found nothing that requires a landlord to tell a renter, so visit a rental at different times of day before you sign.
