G’day travel lovers! Wondering when to pack your swimmers for Port Douglas? This tropical paradise on Queensland’s coast has stunning beaches, easy access to the Great Barrier Reef, and the ancient Daintree Rainforest right on its doorstep.

However, the answer to the best time to visit Port Douglas isn’t as straightforward as you might think. The unique tropical climate means Port Douglas has two distinct seasons – the dry and the wet – each offering their own magic.

While the dry season from May to October brings perfect sunny days and cool nights, the wet season has its own charm with fewer tourists and vibrant greenery everywhere you look. Prices for accommodation also swing dramatically depending on when you visit.

So whether you’re keen to avoid the crowds or the rain, let’s dive into finding what’s the best time to visit Port Douglas.

Best Time to Visit Port Douglas

January

January is the hottest month in Port Douglas with temperatures ranging from 23.6-31.4°C. This is part of what locals call the “green season” rather than the monsoon or wet season. The rainforest looks absolutely luscious during this time, with creeks and rivers flowing crystal clear. Rain typically falls in the late afternoon and overnight, leaving plenty of sunshine during the day for most activities. The whole landscape gets vibrant and full of life, making it a beautiful time to visit despite some cloud cover for about half the month.

February

February continues the green season with temperatures between 23.7-31.1°C. You’ll experience hot days and warm evenings, with afternoon and nighttime monsoonal rains. There’s slightly more cloud cover than January, but the swimming is fantastic all year round in the crystal clear waters. This is an excellent time to visit the rainforest areas when they’re at their most verdant and lush with new growth.

March

March sees slightly cooler temperatures ranging from 23-30.5°C as the wet season continues. This is an ideal time to visit attractions like Kuranda, the Great Barrier Reef, the Skyrail Rainforest Cableway, or explore the Daintree River, Mossman Gorge, and Cape Tribulation. Rain typically falls in the late afternoon and overnight, with light cloud cover for about two weeks of the month, making March perfect for fitting in most sightseeing activities.

April

April marks the beginning of the dry season with temperatures between 21.6-29.2°C. With full days of sun and minimal cloud cover, this is when you can experience the full range of activities that Port Douglas offers. From bungy jumping to hot air ballooning, white water rafting to Great Barrier Reef tours, everything is accessible. The creeks are full, rivers are flowing, and the rainforest displays peak new growth, creating unforgettable natural beauty.

May

May brings a slight cooling trend with temperatures between 19.8-27.6°C. The trade winds start moving up from the south, and water temperatures drop enough that snorkelers and divers may need wetsuits. This transitional period triggers the movement of many migratory species in the area. There’s some cloud cover for about 10 days of the month. May is also special for the Port Douglas Carnival, adding festivities to your visit.

June

June is the first month of winter in Port Douglas and that’s when air temperatures range between 17.7-25.9°C with minimal cloud cover. Water temperatures on the Great Barrier Reef sit around 23°C. This is when Dwarf Minke whales appear in the area (staying until the end of July), often surrounding boats and making this a popular time for diving and snorkeling. Dive tours provide wetsuits to keep you comfortable no matter where you choose to explore.

July

July in Port Douglas features comfortable temperatures in the mid-twenties with water temperatures between 22-25°C—not too hot or cold for anyone. A mid-winter day here resembles a warm summer’s day in Sydney or Melbourne. July marks the start of Humpback whale season, and you’ll almost certainly see these magnificent creatures in their natural environment if you take any Port Douglas cruise during this time.

August

August offers plenty of sunshine and mild warm days, quite different from the cold winter months in Australia’s southern states. Barrier Reef cruises are in full swing, and visitors can fully experience the joys this beautiful spot offers. August is also festival time in Port Douglas with plenty of free entertainment, international performers, and shows to enjoy.

September

September weather in Port Douglas is nearly perfect. Days are pleasant without being too hot, and nights don’t get too cold, with average temperatures around 28°C and very little rainfall. This is an ideal time to visit the Great Barrier Reef, see humpback whales, or go sailing across the pristine waters around Port Douglas.

October

October offers pleasant beach weather—not excessively hot—and the water is free of stingers at this time. Rain tends to fall overnight, making the days enjoyable for activities. Popular attractions during this period include visiting the small rainforest town of Kuranda via the Kuranda Skyrail, and cruises to Green Island remain popular.

November

As the wet season approaches, Port Douglas experiences what locals call the “build-up”—increased humidity and temperatures but relatively little rain. November is great for trying the Kuranda Skyrail and Scenic Railway, which provide spectacular views of the Barron Falls. Cruises to Green Island and the Reef remain excellent options during this time.

December

True summer arrives in December with hot, humid days and nights becoming the norm. Port Douglas is very popular with divers during this time as the crystal clear blue waters provide great visibility of the reef. Summer is the breeding season for many reef fish, creating much underwater activity. Some fish can become aggressive during this time, but dive boats provide plenty of information to keep you safe.
