Lighthouse Beach

Managed by The Swim Guide - Massachusetts

Lighthouse Beach, Chatham's largest, is located on the Atlantic Ocean side of Chatham. The water is much cooler than other Chatham beaches, but its long-stretching sands make it a great place to visit. Parking is restricted to 30 minutes so it's best to arrive by bike, foot, or shuttle bus. The lighthouse makes this beach a very popular destination. The beach is lacking in amenities--there are no washrooms, lifeguards, or food--but it makes up for it with its beautiful views.

SOURCE INFORMATION

The water at marine beaches is tested for the presence of Enterococci, a group of bacterial species typically found in human and animal intestines and are therefore present in sewage. Enterococci is also referred to as indicator organisms. Indicator organisms are used to predict the presence of pathogenic, or disease-causing, organisms associated with fecal contamination.

Swim Guide checks for the latest information daily, Monday - Friday during the swimming season (May through September).

A beach is marked Green when less than 104 units of Enterococci / 100 ml of water is present in a single sample, or when the geometric mean of 5 samples contains less than 35 units / 100ml of water.

A beach is marked Red when more than 104 units of Enterococci / 100 ml of water is present in a single sample, or when the geometric mean of 5 samples contains more than 35 units / 100ml of water.

A beach is marked Grey when there is no current or reliable monitoring information available.
