Nunns Beach is a heavily modified and now artificial beach. The beach lies immediately north of Portland Harbour and is backed by a car park. A long beach originally ran below the white limestone cliffs on either side of Portland Harbour. The harbour construction resulted in erosion of most of this beach and exposure of the backing cliffs. Some sand accumulated on the northern side of the harbour breakwater to form Nunns Beach. In addition, a groyne has been built at the northern end of the 300 m long, east facing beach. In 1990, sand from Pivot Beach was dumped here to replenish the beach.
The beach is well protected by Cape Nelson and the harbour walls. Waves average less than 0.5 m which, with the fine beach sand, ensures a low, shallow beach and attached bar.
A relatively safe beach that gradually shelves out into the Bay.
Better off the breakwater and groyne than the beach.
An accessible, quiet beach suitable for safe swimming.
