Imperial Beach is California's southernmost city, a 4.4-square-mile beach town wedged between the Silver Strand, San Diego Bay, the Tijuana River Estuary and the Mexican border. It was founded in 1887, named to attract residents of Imperial County looking for a summer escape, and incorporated in 1956. About 25,000 people live here, many of them Navy families, longtime surfers and working households priced out of San Diego's northern beaches. The town's assets are hard to match: a 1,500-foot wooden pier, uncrowded surf, the bayfront Bayshore Bikeway and the Tijuana River National Estuarine Research Reserve, the largest salt marsh in Southern California. From 1980 to 2011 it hosted the U.S. Open Sandcastle Competition, which drew hundreds of thousands of visitors. Seacoast Drive and Palm Avenue have filled in with new cafes, a co-op market and the Pier South Resort. It is also a city living with a cross-border environmental crisis. Untreated sewage and runoff from the Tijuana River have kept parts of the Imperial Beach shoreline closed to water contact for most of the past several years, and in August 2026 county officials extended closures from the Tijuana Slough north past the pier to Cortez Avenue. That burden shows up in the numbers: the Census Bureau estimates the population fell 3.4% from 2020 to 2025. Still, Imperial Beach remains the most affordable oceanfront city in the county, with a typical home value near $860,000.
Living here
Draws
- The least expensive oceanfront city in San Diego County
- Uncrowded beach, pier and bay-side bike path
- Large protected estuary and state park on the city's edge
- Small-town scale with its own city government
Tradeoffs
- Recurring sewage contamination and water-contact closures from the Tijuana River
- Longer commute to downtown and North County job centers
- Jet and helicopter noise from nearby Navy airfields
- Limited retail and a population that has been shrinking
Good for: Buyers who want an ocean-town lifestyle at a lower price and can live with frequent water-quality closures.
Weather
Imperial Beach shares the coastal marine climate recorded at Lindbergh Field to the north, with cool summers and mild winters. Fog and low clouds are common from May into July. Winter rainstorms matter more here than elsewhere because they push Tijuana River flows, and pollution, onto the beaches.

What is the weather like in Imperial Beach?
Coastal and mild, similar to Lindbergh Field, where January highs average about 66 degrees and August highs about 77, with roughly 9.8 inches of rain a year. Early summer is foggy, and winter storms often trigger beach closures.
What is Imperial Beach known for?
Its wooden pier, surf breaks, the Tijuana River Estuary and its location as California's southernmost city. It is also known, less happily, for cross-border sewage pollution closing its beaches.
Is the water safe in Imperial Beach?
Often not. County health officials have repeatedly closed the shoreline from the Tijuana Slough to the pier and beyond because the Tijuana River carries sewage into the ocean; in August 2026 the closure was extended to Cortez Avenue. Check sdbeachinfo.com before going in the water.
