Portland Harbour South

Status: No water quality alerts in place


Portland Harbour south is the south end of Portland Harbour where scuba divers are active. There is a storm overflow there for which we receive alerts. Not to be confused with Caste Cove or Sandsfoot, both of which are at the northwest end of the harbour and are designated bathing waters.
