The Great Barrier Reef is one of Australia’s most beautiful natural wonders, and the best place to go diving in crystal clear waters.

Whether you’re a certified diver or a beginner, you may be wanting to know the best months to go diving at the Great Barrier Reef.

The northern sector of the reef is in a tropical area, meaning all year round the water temperature is warm. In the cooler months, it is usually around 24-30 degrees Celsius. While in the warmer months, the water can reach up to 32 degrees Celsius.

To experience the clearer water, you will want to visit in the dry season between April to October. There won’t be any rain which can cause the water to be cloudy.

The most popular time to go diving is from September to December as the water is warmer and heavy rains haven’t set in yet.

But in general, there isn’t a bad time of year when it comes to diving at the Great Barrier Reef. You’ll be able to go diving and discover the underwater paradise and have the chance to swim with a range of marine life no matter the weather.

What diving options are there?

There are multiple tours for the Great Barrier Reef that offer two different diving options. One is scuba diving and the other is helmet diving.

Here is the difference between these two diving experiences.

Scuba diving

Scuba diving allows you to go deeper into the Great Barrier Reef and get up and close to some of the marine life. You’ll even be able to swim side by side with all kinds of animals like tropical fish and sea turtles.

Helmet diving

Helmet diving is a unique experience, and you don’t even need to be a confident swimmer! You will walk along the seabed of the Great Barrier Reef while wearing a helmet connected to an oxygen source. This allows you to get close to larger marine life without having to commit to diving on your own.

What else can I do at the Great Barrier Reef?

You might plan to go diving, but there are still heaps of other activities to do when visiting the Great Barrier Reef.


Snorkelling is one of the popular ways you can get in the water and discover the Great Barrier Reef. You’ll be able to see all the colourful coral and see all kinds of marine life swimming beneath you.

Glass bottom boat

Some tours of the Great Barrier Reef will include a glass bottom boat. You’ll venture out into the water on a boat and look down through the glass to spot all kinds of marine life swimming underneath.
