When is the best time to visit Cairns?

Cairns, in Queensland’s tropical north, offers adventures and experiences for everyone. Families can snorkel on the Great Barrier Reef or meet wildlife in local parks, couples can unwind on deserted white sand beaches or hike through scenic rainforest terrain, and thrill-seekers can kayak, hike, or zip-line through lush landscapes. No matter what kind of trip you’re after, Cairns combines relaxation, natural beauty and adventure in one unforgettable destination.

But is there a best time to visit Cairns? 

The answer depends on what you want to get out of your trip, whether it’s sunny and dry weather, fewer tourists and better prices, or to experience certain activities when they’re at their best, like whale watching or reef diving.

That said, Cairns has plenty to offer year-round, and each season brings something different for visitors to enjoy. 

To help you plan the ideal trip, we’ve put together this guide showing the best times to visit Cairns based on weather, interests, budget, and personal preferences. 

Here’s a quick overview but keep reading for more details and information:

• Overall: April, May and October
• For dry, sunny and pleasant weather: May to October

• For rainforest hikes and waterfalls: May to October 

Best time to visit Cairns for weather

Cairns enjoys a tropical climate with warm temperatures throughout the year. The dry season (May to October) brings sunny, comfortable days, while the wet season (November to April) still offers bright mornings, with hot temperatures, high humidity and intermittent afternoon showers adding to the lush rainforest scenery.

The best time to visit Cairns for comfortable weather that’s dry, sunny and clear is from May to October, in the dry season, however there is still plenty to do in Cairns no matter the weather. 

Here’s a seasonal breakdown of Cairns showing the best activities and experiences for each season of the year:

Dry Season (May to October)

Warm, sunny days and low humidity make this the most popular time to visit. Temperatures usually sit between 18°C and 25°C, and rainfall is low, making it easier to plan outdoor adventures without rain interfering. It’s the ideal time for reef and island tours, snorkelling, swimming, and rainforest hikes.

Wet Season (November to April)

Hot, humid and rainy, with daytime temperatures often between 22°C and 31°C. Mornings are often clear, perfect for reef trips, kayaking, river rafting, or hiking in the Daintree, Barron Gorge, and Atherton Tablelands. Afternoon showers are common, but they bring the rainforest to life: waterfalls flow, the rainforest becomes vibrant, and wildlife is active. It’s also a great time to spot unique animals like cassowaries. Overall, the wet season is great for visitors looking for exciting adventures when visiting Cairns.
 

The dry season is generally the most reliable for planning activities and is considered the best time to visit Cairns. However, the wet season offers lush landscapes, fewer crowds, and vibrant wildlife, making it a rewarding time to visit for those who plan carefully and are happy to be flexible with their daily activities.

Best time to visit Cairns for crowds and prices

Cairns welcomes visitors year-round, but prices and crowds can vary significantly by season. If you’re hoping to save on flights and accommodation, or simply enjoy a quieter experience, it’s worth planning around the city’s busier months.

While the peak of the wet season (December to March) is the quietest time to visit, with the lowest rates for accommodation and flights, it also brings higher humidity and frequent tropical afternoon showers. Still, it’s a good time for travellers who don’t mind a bit of rain. Attractions are quieter, and the rainforest is at its most vibrant, making it an ideal time for scenic drives, short rainforest hikes, and indoor attractions like the Cairns Aquarium.

For the best value trip and better weather conditions, plan your trip during the shoulder months of late April to May or September to early November. These periods sit just outside the peak dry season, meaning you’ll find fewer tourists, lower prices on hotels and tours, and a relaxed atmosphere around town. With warm weather and plenty of sunshine – especially in May, September and October – it’s a great time to enjoy outdoor adventures like reef tours, island hopping, and rainforest walks without the crowds of peak winter travel.

The peak dry season (June to August) is Cairns’ busiest time of year. Perfect weather for exploring both the reef and rainforest means larger crowds and higher prices, especially during July school holidays. If you’re travelling during this time, booking flights, accommodation, and tours well in advance is essential. The reward is clear skies, calmer seas, and ideal conditions for snorkelling, diving, and day trips.

Peak season (June to August)

This is the busiest and most popular time to visit Cairns. Days are warm and sunny, averaging 17°C to 28°C, with low humidity and little-to-no rain - perfect for snorkelling on the Great Barrier Reef, exploring the Daintree Rainforest, or road-tripping to the Atherton Tablelands. 

With the ideal weather, though, comes higher demand and higher holiday costs. Flights, tours, and accommodation prices typically rise, especially in July and August, during school holidays and major events like the Cairns Indigenous Art Fair (July) and the Cairns Festival (August–September). If you’re travelling then, it’s best to plan ahead and book early.

Shoulder season (late April, May, September, October and early November)

If you’re after the best balance of great weather, fewer crowds, and better prices, late April, May, September, October, and early November are the best times to visit Cairns. Daytime temperatures generally range from 20°C to 30°C, with mostly sunny days and relatively lower humidity in May, September and October, making it perfect for reef trips, island hopping, rainforest walks, and scenic drives. 

April and May are slightly cooler and calmer, sitting just after Easter and before the mid-year school holidays, making them some of the quietest months to travel. September and October are warmer with long, sunny days and mild evenings – classic Cairns dry-season conditions without the winter crowds.

Early November still offers pleasant weather, but humidity and rainfall begin to rise as the wet season approaches. It’s typically less busy than winter, so accommodation and tours are easier to secure at reasonable rates. Note that November also marks the start of stinger season, so wearing a protective suit is recommended when swimming on the reef.

Low season (December to March)

Cairns’ low season coincides with the peak wet season, bringing hot, humid weather, frequent afternoon showers, and the occasional tropical storm. 

Temperatures generally range from 23°C to 31°C throughout December, January, and February, with March slightly cooler. Rain can disrupt outdoor plans, though mornings are often clearer, allowing for reef trips, island visits, and short rainforest walks. 

Despite the wetter weather, it’s a good time for travellers seeking quieter attractions, lush landscapes, and lower accommodation prices. Waterfalls are at their fullest, the rainforest is vibrant, and wildlife activity increases with the rain.

There is a higher risk of storms and cyclones, particularly in February and March. December can sometimes offer slightly more settled conditions, though this varies year to year.

Best time to visit Cairns for activities

Cairns is a tropical adventure hub, surrounded by lush rainforests, pristine beaches, and the world-famous Great Barrier Reef. With so much to see and do, both in the city and on day trips to nearby towns and natural wonders, timing your visit can help you get the most out of your Cairns experience.

Reef snorkelling and diving

The shoulder months of April, May, and October are the best times to explore the Great Barrier Reef from Cairns. The crowds are smaller, and the water is warm, clear, and calm, which is ideal for snorkelling and diving. 

In April, while water conditions can occasionally be affected by lingering wet-season rainfall, you may spot juvenile anemone fish playing hide-and-seek among the corals. May is ideal for visiting Outer Reef sites, where vibrant gorgonian fans create a spectacular underwater display. October marks the start of turtle mating and nesting season, giving snorkellers and divers the chance to see green and loggerhead turtles in their natural habitat.

If you’re planning a trip during October or November, remember that stinger season begins around this time, so wearing a protective suit is recommended for safe swimming and diving.

Rainforest walks and hiking

The dry season, particularly from June to August, is the best time to explore Cairns’ rainforests thanks to clear skies, mild temperatures, and lower humidity. Popular rainforest spots for day trips from Cairns include:

• Barron Gorge, where the McDonald’s Track,a moderate hike, showcases dense rainforest and spectacular views over the Barron Gorge as well as waterfalls, lookout points and native wildlife.
• Mosman Gorge, which offers a network of easy-to-moderate walking tracks through lush vegetation and along crystal-clear streams
• Daintree Rainforest, where trails like the Jindalba Boardwalk and Marrdja Walking Track highlight spectacular plants, birds, and reptiles. 
• Cape Tribulation, where the rainforest meets the reef, is perfect for day trips with longer walks or guided tours. Once there, look out for cassowaries, Boyd’s forest dragons, and occasionally saltwater crocodiles – always stay a safe distance from waterways.
• Kuranda is also a must-visit rainforest destination during this season. Visitors can enjoy scenic rainforest walks, explore the Kuranda Village markets for local crafts and souvenirs, and visit wildlife sanctuaries such as Birdworld and the Australian Butterfly Sanctuary to see exotic birds, butterflies, and reptiles.

Waterfalls

Cairns is surrounded by some of Queensland’s most beautiful waterfalls, each offering unique walks, wildlife, and tropical scenery. While the waterfalls can be enjoyed year-round, the best time to visit waterfalls from Cairns is during the wet season (November to April) when the falls are in full flow. Mornings are particularly spectacular, with cascades at their fullest and lush rainforest greenery adding to the vibrant tropical colours of the landscape.

Popular waterfalls that you can visit from Cairns on a day trip include:

• Barron Falls, located in the Barron Gorge National Park, is famous for its dramatic 125-metre drop, especially during the rainy season (November to April) when water flow is at its peak. Once in the park, visitors can enjoy panoramic views from Skyrail's The Edge Lookout or explore nearby walking trails for different perspectives of the gorge and rainforest. 
• Josephine Falls, a short drive from Cairns in the Wooroonooran National Park, features a circuit walk to natural rock pools that are perfect for a refreshing swim. Be sure to be cautious on the slippery rocks. The surrounding rainforest is also home to tree frogs, lizards, and a variety of tropical birds. 
• Millaa Millaa Falls Circuit, a 90-120 minute drive from Cairnsm includes Zillie Falls, Ellinjaa Falls, and Millaa Millaa itself, with accessible walks and photo opportunities, as well as chances to spot wallabies, king parrots, and other native wildlife.

Walking trails at these waterfalls range from easy boardwalks to moderate circuits, so there are options for all fitness levels. 

The combination of flowing water, wildlife, and tropical surroundings makes a visit to Cairns’ waterfalls a must-do activity, whether you’re after swimming, photography, or simply immersing yourself in nature.

Island and beach trips

The best time to visit the islands and beaches near Cairns is May through October, when the skies are clear, seas are calm, and water temperatures are warm – ideal conditions for snorkelling, kayaking, and relaxing on the sand. April can also be pleasant to visit, but rainfall is slightly higher and water clarity may be less reliable than in May to October. During the wet season (November to April), tropical afternoon storms can affect swimming and water activities, so mornings are generally the best time for trips.

You don’t have to head far from Cairns for an island adventure. Just off the coast of Cairns, tropical islands like Fitzroy Island and Green Island offer visitors unforgettable day-trip experiences. On Fitzroy Island, you can snorkel among colourful coral reefs, kayak along sheltered bays, or hike to Fitzroy Summit for panoramic views of both the reef and rainforest. Green Island features calm waters ideal for snorkelling and guided glass-bottom boat tours, along with short rainforest walks where you might spot reef fish, tropical birds, and occasionally turtles.

For beaches closer to Cairns CBD, you can stay on the mainland and explore palm-fringed beaches like Palm Cove and Trinity Beach, both perfect for swimming, sunbathing, and enjoying seaside cafés. A short drive north of an1-1.5 hours brings you to Port Douglas, where Four Mile Beach offers golden sands, calm waters, and opportunities for kayaking or paddleboarding, combined with boutique shopping and local dining.

Crocodile river cruise

One of the top things to do in Cairns is to spot crocodiles, and the best time to do this is during the dry season, May to October, when the weather is calm and crocodiles are most visible basking in the sun.

For an unforgettable wildlife adventure, head about two hours north of Cairns to take a crocodile cruise along the Daintree River, one of the area’s top attractions. Gliding along the winding river, you’ll be able to spot massive saltwater crocodiles, as well as rare birds like kingfishers, egrets, and herons, and other tropical wildlife in their natural habitat. Experienced guides will share fascinating insights into the river’s ecosystem, crocodile behaviour, and conservation efforts, making the cruise both exciting and educational.

While dry season is optimal, cruises operate year-round. Departures can be affected by weather conditions, so it’s best to check in advance. The best time of day to take a crocodile cruise along the Daintree Rive is early morning or late afternoon. These times are particularly good for spotting these iconic reptiles actively swimming or resting along the riverbanks.

Art, culture and food experiences

Beyond its natural wonders, Cairns has a thriving arts and cultural scene, and the best time to enjoy it is during the dry season (May to October) when outdoor markets, cultural tours, and street food events have less chance of being impacted by rain. To avoid the crowds of peak season, book your trip for May, September or October.

Some of the most popular spots to tick off include:

• The Cairns Art Gallery, which showcases contemporary and Indigenous Australian art, and offers workshops and guided tours that provide insight into the region’s rich Aboriginal heritage. 
• Rusty’s Markets, a weekend farmers market for food lovers and shoppers alike. With 180 stalls, visitors can explore the fresh tropical produce, flowers, deli items and fresh bread, dairy and seafood, or shop for jewellery, clothers and bric-a-brac.
