Why Should You Visit Cairns?

You likely already have a few good reasons for wanting to visit Cairns. But in case you need extra convincing, here are some of the reasons we love Cairns:


Cairns Seasons

Firstly, there isn’t a drastic change between seasons in Cairns and Tropical North Queensland compared to the southern part of the state and most other states in the country.

Cairns weather is fairly consistent all year round with warm weather (warm to hot, anyway).

Still, each season in Cairns has its own unique charm but also comes with its own set of considerations.

You could also argue that Cairns really has two main seasonsthe wet season and the dry season.

Winter In Cairns (June – August)

Winter? What winter? Winter in Cairns are more like a mild summer in most other places in Australia, with temperatures averaging around 25°C during the day and dipping to a cool 17°C at night.

The water temperature sits comfortably around 23°C, perfect for a dip or snorkel. It’s a great time to visit if you’re not a fan of scorching heat.

Cairns in winter is also a great place to go if you’re chasing the winter sun!

Spring In Cairns (September – November)

Spring is another fabulous time to visit Cairns.

The temperatures start to climb a bit, but it’s not too hot yet. Expect daytime temps around 30°C and water temps creeping up to around 26°C.

This is a great time for outdoor activities and day trips before the crazy summer heat and humidity fully kick in!

Summer In Cairns (December – February)

Summer in Cairns can get steamy, with daytime temperatures soaring up to 35°C (and higher). The average temperature for December to February is around 31 degrees Celcius each day, making them equally the hottest month of the year to visit.

The water temperatures are warm, sitting around 29°C – like a nice, warm bath.

The humidity can be quite high, but it’s manageable with regular dips in the water and plenty of hydration.

This is also the time of year when you’re more likely to experience some tropical rain, which typically falls in heavy but short bursts. It’s a spectacle to behold but can occasionally interfere with outdoor plans.

That said, the rain rejuvenates the rainforests, making them bright, lush green, and cools down the day’s heat. This is why they also call it the ‘green season’.

Not so fun are the tropical cyclones that can also come during storm season.

Autumn In Cairns (March-May)

Autumn is a sweet spot for visiting Cairns with less humidity than summer, and cooler temperatures between 26°C – 30°C. Water temps remain warm at around 25°C, making it still perfect for water activities.

However, it’s the tail end of the wet season, so expect some rain as the humidity levels start to come down.

The Worst Time To Visit Cairns

It’s not all sunshine and rainbows in paradise. There are a couple of times when you might want to rethink your travel plans.

Those times are typically the stinger season (jellyfish) and the Cairns wet season.

Here are some tips on avoiding the worst time to visit Cairns:

When Is Stinger Season In North Queensland?

Stinger season usually runs from November to May. These critters can give a nasty sting, so if you’re planning on swimming in the sea, wear a stinger suit or stick to the netted beaches.

The two jellyfish you will likely encounter during the Cairns stinger season are Irukandji and box jellyfish.

Both of these can have very severe consequences and are classed as dangerous tropical marine stingers.

There are many patrolled beaches in North Queensland with marine stinger enclosures.

These do a reasonable job of keeping the larger box jellyfish out, but not such a good job with the smaller Irukandji. These operate between November and May.

You can further protect yourself by wearing protective swimming gear, such as a stinger suit. This will also help protect you from the harsh UV rays in north Queensland as well.

When Is The Cairns Wet Season?

The wet season typically spans from December to April, with the heaviest rainfall often between February and March.

Expect heavy rains and potential cyclones. The cyclones can be scary but less common than the typical heavy tropical storms you will see in the late afternoon.

It’s a spectacular time for waterfalls, but many roads and attractions may be closed due to flooding.

We were lucky when we last visited Paronella Park on a day trip from Cairns just a week before one of their many floods – the area we were standing was underwater a few days later and is often flooded throughout the year.

It shows how quickly the heavy rains can impact certain areas in the tropical north.

When Is The Cairns Peak Season?

Peak season in Cairns aligns with Australian school holidays, approximately mid-December to late January, early April/Easter break, late June to early July, and late September to early October.

Prices can skyrocket for Cairns accommodation and car rental, and attractions can get crowded, so plan accordingly.

There are a few things to consider if you want to visit Cairns during the best possible time:

To avoid the crowds and high prices, consider visiting outside of school holiday periods.

The climate is most comfortable from May to October, avoiding the extreme heat, wet season, and stinger season.

Plus, travelling in off-peak times might score you some sweet travel deals and cheaper prices for hotels!

If you do decide to visit during stinger season, make sure to hire a stinger suit for swimming – better safe than sorry, folks!

Conclusion – When Is The Best Time To Go To Cairns?

Honestly, there’s no ‘bad’ time to visit Cairns – each season offers a unique experience. But if you’re looking for comfortable temperatures, fewer crowds, and lower prices, plus fewer chances of jellyfish encounters and flash flooding, May to October is your best bet.

We have visited in the middle of winter and it was lovely. We’ve had equally great times visiting in the shoulder season of Spring for perfect pool weather and fine for outdoor activities if you get an early start and beat the hottest part of the day.
