San Diego is California's southernmost major coastal city, at coordinates 32.715695°N, 117.161719°W on the Pacific coast just north of the Mexico border. For submarine cable infrastructure, San Diego is a relatively new but rapidly developing trans-Pacific landing point. Two major hyperscaler-led cables are scheduled to land here over the next few years — Honomoana (Google, RFS 2026) and APX East (SUBCO, RFS 2028) — both connecting San Diego to Australasia, the Pacific Islands and Hawaii.
San Diego's emergence as a trans-Pacific cable hub complements the longstanding Los Angeles-area landings (El Segundo, Hermosa Beach) and the Pacific Northwest cluster (Hillsboro, Pacific City). The geographic separation from these existing US west coast clusters provides landing-end diversity for trans-Pacific traffic, which has historically concentrated risk at a small number of California beach manholes.
Honomoana is a 15,215 km submarine cable scheduled for ready-for-service in 2026, owned by Google. From San Diego it will reach Auckland (New Zealand), Faratea and Papenoo (French Polynesia), Melbourne and Sydney (Australia). Honomoana is part of Google's hyperscaler trans-Pacific cable buildout, providing dedicated capacity for AI training data flows and CDN edge connectivity in the Pacific region.
APX East is a 13,000 km submarine cable scheduled for ready-for-service in 2028, owned by SUBCO. From San Diego it will reach Sydney (Australia), Suva (Fiji), and Kapolei (Hawaii). APX East provides a dedicated trans-Pacific path with explicit Pacific Islands stopovers, addressing the connectivity gap for smaller Pacific nations that historically depended on indirect routing.
Once both cables enter service, San Diego will host two trans-Pacific systems with overlapping but distinct destination footprints. Both reach Sydney (Australia) and a Hawaiian landing (Honomoana via planned routing, APX East via Kapolei explicitly), creating Australia-Hawaii route redundancy for San Diego-bound traffic. The cables differ in operator (Google vs. SUBCO) and partial destinations (Honomoana also reaches French Polynesia and New Zealand; APX East reaches Fiji).
Until 2026, San Diego is not yet an active submarine cable landing in the GeoCables dataset. The page exists as documentation of the planned infrastructure and provides a reference point for users searching for "San Diego submarine cable" or "California Pacific cable landing".
The San Diego submarine cable landing zone sits at 32.715695°N, 117.161719°W (32°42'56"N, 117°09'42"W), on the Pacific coast of southern California. The deep-water access of the eastern Pacific provides direct trans-oceanic cable corridors with relatively shallow continental shelf approaches.
Two major submarine cables are scheduled to land at San Diego: Honomoana (planned RFS 2026, Google, to Australasia + French Polynesia + New Zealand) and APX East (planned RFS 2028, SUBCO, to Australia + Fiji + Hawaii). No cables currently in service at this landing.
The San Diego cable landing zone is at 32.715695°N, 117.161719°W (32°42'56"N, 117°09'42"W), on the Pacific coast of southern California.
Through Honomoana (2026), San Diego will connect to Australia (Sydney, Melbourne), New Zealand (Auckland), and French Polynesia. Through APX East (2028), San Diego will connect to Australia (Sydney), Fiji (Suva), and Hawaii (Kapolei).
The first scheduled San Diego landing in the GeoCables dataset is Honomoana, planned for 2026. APX East follows in 2028.
Honomoana is owned by Google. APX East is owned by SUBCO, an independent submarine cable infrastructure operator focused on Pacific routes.
