For 2026, Palm Beach, Florida, remains the wealthiest beach town in the United States when measured by average household income and property values. According to recent 2025-2026 wealth rankings, the average household income in Palm Beach exceeds $350,000, and the average home value is now over $10 million. Other contenders for the title include Atherton, California (though not directly on a beach, its proximity to the coast makes it a perennial wealth leader) and Manhattan Beach, California, which has an average household income near $300,000 and a high concentration of ultra-wealthy residents. In the Northeast, Southampton, New York, continues to dominate the "Hamptons" wealth bracket with some of the most expensive real estate in the country. Palm Beach's unique position as a global tax-haven hub for billionaires and its "Gilded Age" heritage ensures it maintains the highest concentration of individual wealth of any coastal enclave in the nation this year.
