Townhouse for Sale in San Marino Island, Miami Beach

San Marino Island is a small, primarily residential artificial island in Biscayne Bay that’s part of the Venetian Islands chain in Miami Beach, characterized by waterfront single-family homes and private docks. Living there is quiet and upscale with low density and limited on-island commercial amenities, so residents rely on nearby Mid‑Beach, South Beach, or mainland Miami for shopping and dining. Transportation is car-oriented via the Venetian Causeway and local roads; public transit is limited, but the island offers direct bay access for boating. Home values and overall cost of living are high compared with the Miami metro, and the area faces sea-level rise and hurricane-related flood and storm-surge risks common to Biscayne Bay.

Yes. San Marino Island is one of Miami Beach’s most expensive neighborhoods, composed mainly of waterfront single‑family estates that commonly sell for several million dollars. Owners typically face high property taxes, homeowners insurance and maintenance costs associated with luxury barrier‑island properties. Prices are comparable to nearby upscale islands such as Palm and Hibiscus.

San Marino Island has a tropical climate with hot, humid summers and warm, mild winters. The rainy season runs roughly May–October with frequent afternoon thunderstorms and the Atlantic hurricane season (June 1–Nov 30) bringing elevated wind and storm‑surge risk. Typical summer highs are about 88–91°F (31–33°C) with lows around 75–79°F (24–26°C); winter highs are around 70–77°F (21–25°C) with lows near 60–65°F (15–18°C). Sea breezes moderate temperatures, annual rainfall is high (~60 in / 1,500 mm), and the area experiences periodic coastal flooding during king tides and storm events.
