Can You Swim in the Sea in Perth? – Understanding the Water Conditions

Before swimming, you must understand the water conditions of the Indian Ocean as this knowledge ensures a safe experience. 

Water Temperature

The water temperature in the Indian Ocean off Perth’s coast varies throughout the year. In summer, from December to February, the water ranges from 18°C (64°F) to 26°C (79°F). During winter, from June to August, the water temperature drops to around 17°C (63°F) to 21°C (70°F).


Perth experiences various ocean currents and tides that influence its water conditions. The Leeuwin Current, a warm ocean current, flows southward along the western coast of Australia, including Perth. It brings tropical water from the north, contributing to the warmer temperatures during summer. 

Potential Hazards

While Perth’s Indian Ocean has beautiful beaches, it’s important to be aware of potential hazards. Here are a few to keep in mind:

  1. Rip Currents: Perth beaches can have strong rip currents, particularly around sandbars or channels. These powerful currents can quickly carry swimmers away from the shore. It’s essential to recognise the signs of a rip current, such as discoloured or choppy water, and know how to swim out of them or signal for help.
  2. Marine Life: Perth’s waters are home to various marine life, including jellyfish and occasionally sharks. Pay attention to any warnings or signs posted by local authorities regarding potential marine hazards.
  3. Underwater Rocks and Reefs: Some areas off Perth’s coast have rocky or reef formations. These can be hazardous, especially during low tide or when waves break over them. Be cautious when swimming, snorkelling, or diving near these areas to avoid injuries.

Seasonal Variations

During summer, when the water is warmer and weather conditions are generally calm, swimming is a popular activity. However, it’s important to follow beach safety guidelines, swim between the flags at patrolled beaches, and listen to lifeguards’ instructions.

In winter, the water temperature drops, and weather conditions can be more unpredictable. Strong winds, larger swells, and colder water make swimming riskier.

Many coastal areas in Western Australia are part an ecosystem where sharks may be present. However, it is important to emphasize that shark encounters are infrequent, and numerous precautions are implemented to minimise the risk and ensure the safety of beachgoers.

Surf Life Saving WA and other local authorities actively monitor the ocean, promptly informing the public about any shark sightings. To enhance safety measures, shark monitoring and detection systems, such as aerial patrols and shark detection buoys, are used.

To ensure your safety while at the beach, it is advised to be mindful of your surroundings, swim between the designated flags, and avoid swimming during dawn and dusk when sharks are more active.

If you have any concerns or want the most recent information regarding beach safety and shark activity, it is advisable to consult the lifeguards responsible for the beach. They are equipped to provide you with the latest updates and guidance.

Safety Measures & Precautions

When enjoying the beautiful beaches and water activities in Perth’s Indian Ocean, here are some tips and precautions to keep in mind:

1. Check Local Advisories: Before heading to the beach, check for any warnings regarding water conditions, hazards, or closures. This information can be obtained from local authorities, lifeguards, or official websites like SLSA Beachsafe.

2. Understand Rip Currents: Educate yourself about rip currents, their characteristics, and how to recognise them. If caught in a rip current, remain calm, swim parallel to the shore, and gradually make your way back to safety. Signal for help if needed.

3. Swim Between the Flags: Patrolled beaches in Perth have designated swimming areas marked by flags. These areas are closely monitored by trained lifeguards. It’s advisable to swim between the yellow and red flags as they indicate safer zones with fewer hazards.

4. Protection: Protect yourself from the sun’s harmful rays by applying sunscreen before entering the water. Choose a broad-spectrum sunscreen with a high SPF and reapply regularly, especially after swimming. Wearing a wide-brimmed hat, sunglasses, and a rashie can provide additional protection.

5. Swim with a Buddy: It’s always safer to swim and snorkel with a companion. Having someone nearby can provide assistance in case of an emergency or if you encounter any difficulties in the water. Look out for each other and communicate your plans and intentions.

6. Observe Weather Conditions: Keep an eye on the weather forecast and be aware of any changes in conditions. Avoid swimming during storms, strong winds, or when there are large swells. These conditions can increase the risk of accidents and make swimming more challenging.
