: Barrenjoey Beach, Paradise Beach Baths, Clareville Beach, Bayview Baths, North Scotland Island, South Scotland Island, Winji Jimmi Bay, , Elvina Bay, The Basin and Great Mackerel Beach  Ocean beaches: Palm, Whale, Avalon, Bilgola, Newport, Bungan, Mona Vale, Warriewood, Turimetta, North , Collaroy, Long Reef, , North , South Curl Curl, Freshwater, Queenscliff, North Steyne, South Steyne and Shelly (Manly)  Lagoon: Birdwood Park (Narrabeen Lagoon)  North Harbour: Little Manly Cove, Manly Cove, Forty Baskets Pool and Fairlight Beach.

The excellent results were due to the dry weather conditions. Rainfall at Observatory Hill during August was only 6 mm, well below the long-term average of 81 mm. As a result, waterways were free from the impacts of sewage-contaminated stormwater and wet weather sewage overflows.

Beachwatch recommends that you avoid swimming for one day after heavy rainfall at ocean beaches and for up to three days after rainfall at harbour beaches.

Before heading to the beach, particularly after it has been raining, check pollution levels by phoning the Beachwatch telephone information line on Freecall 1800 036 677 or check the Beachwatch website at www.environment.nsw.gov.au/beach.

When at the beach, look for signs of stormwater pollution such as discoloured water, or litter in the water or on the tide line before entering the water.
