Compo Beach extends along Long Island Sound in Westport, Connecticut, offering a sandy beach within a 29-acre seaside park. Access via Compo Beach Road with ample parking available for a seasonal fee. The park includes restrooms, outdoor showers, changing facilities, concession stands, and extensive picnic areas with grills. The beach opens at dawn for residents and closes at dusk, with lifeguards on duty during summer months from Memorial Day through Labor Day.
The wide sandy beach provides excellent swimming conditions with gradual entry into Long Island Sound. The swimming area features designated sections monitored by lifeguards, with calm waters typical during morning hours before afternoon winds develop. Distance swimmers can follow the shoreline for extended parallel swimming, with good water clarity and visibility during most conditions. The beach’s westerly orientation provides some protection from prevailing southwesterly winds.
Compo Beach hosts the Point to Point Compo Beach Swim, a popular open water swimming event held annually. The race showcases the quality swimming conditions available at this location. Local swimmers use the beach for regular training, particularly during early morning hours when the water is calmest and crowds are minimal. The beach’s reputation as a premier Connecticut swimming venue attracts serious open water swimmers preparing for distance events and competitions.
Water quality monitoring is conducted by the Connecticut Department of Public Health with regular testing throughout the swimming season. Additional monitoring data is available through the [EPA Beacon system](https://beacon.epa.gov/ords/beacon2/f?p=beacon2:38:1::NO::P38_BEACH_ID:CT135112). The town provides daily water quality updates during summer season. Avoid swimming within 24 hours following heavy rainfall. The park’s facilities and excellent swimming conditions make this a favorite destination for both recreational swimmers and competitive open water athletes in the greater Fairfield County area.
