Learn more about the captivating world of bioluminescence, including the causes, the best time to see it, and the idea

l location to experience this natural marvel.

When you stroll around the pristine beach in Jervis Bay at night in a particular season, you will be amazed at its water, which can glow in the dark.

The blue light shining in the water is caused by bioluminescent algae named Noctiluca. This tiny creature can emit light as a defence mechanism when threatened. So, when the waves crash, the water shines like blue light.

This beautiful glow is a result of a chemical reaction inside the algae. When they are disturbed by the water movement, it triggers a complex process involving luciferase enzymes. This process releases energy in the form of glowing blue light.

You can only see this extraordinary phenomenon at night. However, it is hard to determine the best time to witness bioluminescence.

This phenomenon occurs every year for different months. For instance, in 2019, it appeared in mid-May. Then, in January 2020, the bioluminescence looked incredible. In 2023, you could see this magical blue light glow in December.

Usually, this natural wonder appears during the warmer months (December – March). In these months, the water temperature is warm and ideal for the proliferation of Noctiluca.

Sometimes, bioluminescence appears throughout the year. However, the intensity and frequency of the display will be higher during the warm months.

If you want to experience the best water glow, visit Jervis Bay on a moonless night. The darker the night, the more vibrant the glow is. Furthermore, the night with a cloudy sky is another good time to explore the beach. It will enhance the visibility of bioluminescence.

Several beaches in Jervis Bay offer the most mesmerising bioluminescence displays in the world. Every location provides a different experience to witness this natural water glow.

Here are five recommendations for the best beach for bioluminescence in Jervis Bay.

Barfleur Beach is located near Vincentia. Since Barfleur Beach is relatively secluded, it becomes a perfect spot to observe the natural light show.

Additionally, it has minimal light pollution, so the visibility of the water glow is enhanced. The gentle waves on this beach offer an ideal environment for the bioluminescent organism to shine brightly.

Nestled in the Shoalhaven region, Hyams Beach is famous for its white sand. According to Guinness World Records, this beach has the whitest sand in the world.

During the day, Hyam Beach offers stunning scenery because of the contrast between the bright sand and blue water. Then, this coastline becomes a great spot to hunt bioluminescence shows in the dark and moonless night.

This beach is located at the southernmost tip of Jervis Bay. Surrounded by bushes, this beach offers an excellent location to witness the glowing water.

In addition to experiencing the bioluminescence at night, you can also visit this beach during the day to go snorkelling. The marine life on this beach is worth exploring.

This beach is situated in Booderee National Park. Unlike other beaches in Jervis with soft sands, Scottish Rock has a rocky shore. Even though the beach is secluded, it offers a stunning spot for snorkelling.

Additionally, Scottish Rock is also an ideal spot to see bioluminescence. When the waves hit the rocks, the glowing effect is enhanced.

Unfortunately, it only has a small parking area. Also, you have to walk through the bushland to reach the beach.

Located near Vincentia, Orion Beach is another great spot for bioluminescence. This beach offers calm waves, perfect for observing the glowing water.

This beach has a footpath so you can access it easily. You can visit this beach all year round. During summer, you can do a lot of fun activities like swimming, snorkelling, or having a picnic.

Exploring the bioluminescence Jervis Bay phenomenon will be a memorable experience for local and foreign travellers. To ensure you can catch the awesome light show, follow several essential tips below.

If you plan to visit New South Wales for vacation, make sure to come during the warm months. This is when you are more likely to witness the best bioluminescence.

Also, visit the beach on a cloudy or moonless night. Without moonlight, glowing water appears more appealing and clearer.

When exploring the beach, minimise the use of flashlights. The use of artificial light can wash out the glow. If you want to capture this phenomenon using your camera, make sure to adjust the setting first.

For instance, the ISO setting should be increased between 800 and 1600 because the environment has very low light. Then, use the widest aperture to let in the light. Last, you should turn off the flashlight when capturing the image.

Is it safe to swim in bioluminescence? The answer is no. Even though the Bioluminescence in Jervis Bay Beach looks mesmerising, you should not touch or swim in it.

Many bioluminescent organisms are toxic. Certain dinoflagellate species can be poisonous to humans. Be aware of algal blooms, which are an overgrowth of dinoflagellates. They can be harmful and irritate your skin. Therefore, just enjoy the beauty of nature without touching it.
