When’s The Best Time To Visit Cairns, Australia
When you visit a particular destination, it’s always important to check beforehand what the best season to visit is. You don’t want to visit Russia in the middle of winter or the Sahara in the middle of summer – nor do you want to get yourself stuck in the middle of a cyclone season, drought or flood. The same applies to determining when to visit Cairns. Frankly, locals will tell you that any time is the best time to visit this gorgeous region – and they’d be right; however, there is a marked difference between the varying seasons in Cairns and – depending on what you’d like to do when visiting – the climate can have a dramatic effect on your enjoyment.
The Tropical North Queensland region experiences two distinct seasons – the wet season and the dry season. The summertime wet season in Cairns is generally hot and humid, with an average annual rainfall of around 1992 mm (average of about 396 mm in January). This wet monsoonal season begins to develop in December, peaks in January and lasts through March. With daytime temperatures of 23 to 31 degrees Celsius, a scorching day is often followed by a cooling evening shower, which is welcomed by all.
During the summer season, the rainforests surrounding Cairns are at their finest. The Daintree and Cape Tribulation are bursting with life and the rivers and waterfalls are gushing, meaning that activities like rainforest tours, the Kuranda Skyrail and white water rafting are ideal. At this time of year, the Great Barrier Reef is also phenomenal, with perfect water temperatures and visibility up to 50 metres.
By the time April comes around, the weather has settled down a bit and the dry season begins. While it’s still quite hot – with temperatures ranging from 22 to 29 degrees – the drier weather means Cairns is perfect for those activities that are best done without the rain, like bungy jumping or hot air ballooning.
During the winter months (June to August), Cairns is at its most pleasant, with temperatures ranging from about 17 to 26 degrees. The weather is usually dry with clear skies and calm winds, meaning almost any activity is perfect – particularly sailing and other activities that rely on calm weather. During the winter season, you’ll also get the chance to see migrating humpback whales!
From September to December, the weather begins warming up again, but springtime is a delight, with blooming plant life and plenty of animal activity, making it the perfect time to visit parks, gardens and wildlife attractions. The Reef springs to life with the yearly coral spawning event and the birds go through their colourful mating rituals. While daytime temperatures often reach 30 degrees Celsius (with an average low of around 21 degrees), these are often followed by a stormy evening that makes for a spectacular lightning-charged showcase.
So, the locals are right when they suggest that any time is perfect for visiting Cairns, depending upon what you’d like to experience. If you love hot summery weather, lounging on the sand and frolicking through the water, the summer months are definitely the best. If you’re sensitive to the heat or want to ensure your activity isn’t spoiled by the chance of rain, wintertime is perfect. If you’re simply after an absolutely perfect tropical paradise, come whenever suits you!
