Best time to visit Port Douglas

March 9, 2024

Port Douglas is an amazing place to visit at any time of the year. The beautiful harbour town is one hour north of Cairns, so it is well within the tropics. For travellers that haven’t visited the tropics before, Port Douglas is a wonderful base to explore: miles of tropical sandy beaches, access to the Great Barrier Reef and close to pristine tropical rainforest.

Being a tropical location, Port Douglas essentially has two seasons: The wet and dry season. The wet season is from November to April. During this time you can expect average temperatures to be around 30 degrees Celsius, with an average monthly rainfall of 375mm. March is generally the wettest month. However, this rainfall can be a welcome release for those travellers that don’t like the weather too humid, and the rainforest, in particular, looks incredible during this season – teeming with life, and with the waterfalls in full flow.

There isn’t a time of year that would be unsuitable for a great vacation, but depending on your priorities, some months may be better than others. Try the month of May when Port Douglas is bursting with excitement as locals and visitors alike celebrate Carnivale!

Wintertime, dry season

The dry season is from March to October. Though cooler, temperatures are still warm with an average temperature between 20-25 degrees Celsius. There is far less rainfall during this season-some months as little as 25mm. In the sea, the water temperature will still be warm. The average temperature for June-August is a perfect 22 degrees Celsius.

Of course, some vacation activities are not weather dependent at all. Port Douglas is a luxury resort, and Macrossan Street, the main hub of the town, boasts a great variety of boutiques, restaurants, bars, galleries and designer shopping. At one end of the street is the picture-postcard beautiful Four Mile Beach, and at the other end is Anzac Park which hosts a wonderful local market every Sunday.

Great Barrier Reef

Port Douglas is a great base from which to explore the Great Barrier Reef – the world’s largest and most breathtaking reef. From Port Douglas, you could explore the reef by boat or by helicopter and there are a number of tour companies that offer this service in the town. When you are out on the reef just make sure to keep an eye out in the hopes that you can find Nemo!

The reef can be visited at any time of year, but if you travel during the rainy season (November-April) be aware that adverse weather conditions (monsoon or storms) may mean that boat trips may be cancelled or delayed. A safer bet would be to visit during the dry season.

Daintree rainforest

The Daintree forest is a spectacular, untouched tropical rainforest 1 ½ hours north of Port Douglas. It covers over 1200 square kilometres and is a naturalist’s paradise. It contains the largest range of plants and animals on earth, including giant reptiles (crocodiles and pythons), birds and marsupials. The rainforest is also the oldest in the world – over 135 million years old. Tours like Daintree Rainforest Tours will take you to this beautiful area in luxury air-conditioned comfort.

The Daintree rainforest may be visited at any time of year: May to September will be cooler, but the rainforest canopy tends to keep ground level surprisingly cool anyway. Visiting during the rainy season can be spectacular – nature at its wildest with raging waterfalls, hot tropical rain and an abundance of wildlife.

At the north of Daintree is Cape Tribulation: a beautiful headland full of eco-resorts, beaches and excellent access to the rainforest. Cape Tribulation was named by Captain Cook whose ship scraped a reef north-east of the Cape.

During the winter season (May-Sept) you may be lucky enough to see the extraordinary sight of the arrival of the migrating humpback whales.

Saltwater Crocodiles are also easier to spot at this time of year when they spend large parts of the day warming themselves on the banks of the Daintree River.

From Sept to Dec, the annual coral spawning event takes place by a full moon, and tropical birds begin their elaborate mating displays.

Other considerations: the Box Jellyfish

During the rainy season, the notorious box jellyfish are present in the waters of Northern Queensland, so extra care should be taken in the water. Four Mile Beach in Port Douglas has a safety net in operation during this time, so ensure to swim within this area.
