Perth is a kind coast for a family beach day, but the gentlest version takes a little planning. The Indian Ocean here is clean and the sand is soft white quartz, yet the open beaches face the swell and the afternoon sea breeze, so the calm water small children need lives in the sheltered corners: the reef pool at Mettams, the enclosed beach inside Hillarys Boat Harbour, and the broad, well serviced family beaches with grass and playgrounds behind the sand. Match the beach to the age of your children and the hour of the day and a Perth family beach day is one of the easiest and loveliest anywhere.
Below we rank the family beaches the way a parent actually chooses one, by how calm and shallow the water tends to be, how much shade and how many facilities sit behind the sand, and how easy the whole day is to run with children. We are honest about which beaches are patrolled and which are not, which add a playground or a marina and which are simply sand, and we never promise safety, because conditions are always typical rather than guaranteed. Watch children closely in the water and swim between the flags wherever they fly.
Ranked for families
Scored on calm water, shade and facilities, and the ease of a day with children.
City Beach
The easiest all round family day in Perth, with a broad gently sloping beach, a grassed foreshore, playgrounds, surf clubs and restaurants and easy parking. It is patrolled in season and the wide sand gives children room, though it is open ocean, so come in the calm of the morning for the gentlest swim.
Mettams Pool
The calmest water on the Perth coast, a shallow reef protected lagoon where the offshore reef softens the swell into clear, gentle water and small fish drift over the rocks. It is ideal for a toddler paddle and a first snorkel on a settled morning, though it is not always flagged, so watch children closely.
Hillarys Beach
The sheltered swimming beach inside Hillarys Boat Harbour is calm and shallow, protected from the swell, and ringed by cafes, shops and family attractions at the marina. It is the easy choice for nervous swimmers and a full day out, with plenty to do when the children tire of the sand.
Sorrento Beach
A relaxed, gently shelving family beach just south of Hillarys, with a grassed foreshore, a surf club and cafes, and a calmer feel than the busy central stretches. The water is usually settled on a morning, which makes it an unhurried choice for a quiet day with younger children.
Mullaloo Beach
A wide, calm family beach in the northern suburbs with a grassed reserve, a playground, a surf club kitchen and a sheltered feel that draws local families. It is patrolled in season and spacious enough to spread out, an easy and comfortable day a little further from the city.
Cottesloe Beach
The famous terraced beach is patrolled, serviced and lovely for an older family, with the grassed terrace, kiosks and the pavilion behind the sand. It is busier and more open than the sheltered options, so bring it down to a dawn swim and a breakfast before the crowd and the sea breeze arrive.
Which beach for which family
A few honest pointers. For the calmest, shallowest water with toddlers, the reef pool at Mettams and the enclosed beach inside Hillarys Boat Harbour are hard to beat, because both are sheltered from the swell that runs along the open coast. For an easy all round day with grass to picnic on, a playground and a surf club kitchen, City Beach, Sorrento and Mullaloo are the comfortable picks, all patrolled in season and built for a family day.
Now the honest steer away. The lively esplanade at Scarborough is fun for older children and has a beachfront pool, but it is busy and the open water can be choppy, and the surf at Trigg carries rips that make it a beach for confident swimmers and surfers rather than little ones. Plan around the wind above all: the sea is glassiest in the morning, and the afternoon Fremantle Doctor reliably ruffles the open coast, so an early start gives you the calmest water and the easiest day. The warmest water runs from December to April, while the spring and autumn shoulders are gentler on the crowds and just as pleasant.

Before you go
Which is the best beach for families in Perth?
For the gentlest water with young children, the reef pool at Mettams and the sheltered swimming beach inside Hillarys Boat Harbour lead, both shallow and protected from the swell. For an easy all round day with grass, playgrounds and surf club kitchens, City Beach and Mullaloo are the comfortable picks. Cottesloe is patrolled and lovely but busier and more open.
Which Perth beach has the calmest, shallowest water for small children?
Mettams Pool is the calmest, a shallow reef protected lagoon at North Beach where the offshore reef softens the swell into clear, gentle water, and the enclosed swimming beach inside Hillarys Boat Harbour is sheltered and shallow too. Both suit toddlers and a paddle, and conditions are always typical rather than guaranteed, so watch children closely.
Are Perth family beaches patrolled?
The main beaches such as Cottesloe, City Beach, Mullaloo and Sorrento are patrolled with flagged swim areas in the summer season, which makes them the right choice for a secure family swim. Mettams and the Hillarys harbour beach are calmer but not always flagged, so read the conditions, swim between the flags where they fly, and treat the sea as typical and never guaranteed.
Where can families find shade and facilities at Perth beaches?
City Beach, Sorrento and Mullaloo have grassed foreshores, playgrounds, surf clubs and cafes, and Hillarys pairs its calm beach with a marina full of food and family attractions. Natural shade on the open sand is limited, so bring your own umbrella, and plan around the cooler morning hours before the afternoon sea breeze.
When is the best time for a family beach day in Perth?
The warm months from December to April give the warmest water and the easiest swimming, with the calmest sea in the mornings before the afternoon sea breeze known as the Fremantle Doctor builds. The spring and autumn shoulders are gentler on crowds and just as pleasant, so aim for a settled morning whenever you go.
