Cairns in September

September is an excellent month to visit Cairns, combining the reliable dry-season weather of winter with the warmer temperatures of tropical spring.

Rainfall is generally low, humidity remains relatively comfortable and sunny days are ideal for exploring the Great Barrier Reef, Daintree Rainforest, tropical beaches and mountains surrounding Cairns.

As spring arrives, temperatures begin to climb, although the intense heat and humidity of the wet season are still some way away. The Great Barrier Reef remains a major attraction, with comfortable conditions for snorkelling and diving.

September is also a popular month for outdoor adventures, with excellent conditions for hiking, rafting, scenic flights and rainforest tours.

For visitors looking for warm weather, low rainfall and plenty of sunshine without the peak summer heat, September is one of the most appealing months to experience Cairns.

What is Cairns Like in September?

September is warm, sunny and generally dry.

It is the final full month of the dry season, although the climate gradually becomes warmer as spring progresses.

Long-term Bureau of Meteorology climate statistics put Cairns’ September mean maximum temperature at approximately 27°C. 

Mornings and evenings are generally becoming warmer than they were in June and July, while daytime temperatures are very comfortable.

You can generally expect:

• Warm sunny days
• Mild to warm evenings
• Low humidity
• Very little rainfall
• Clear skies
• Excellent reef conditions
• Comfortable hiking weather
• Whale-watching opportunities
• Increasingly warm ocean temperatures
• Tours and Accommodation busier

September is particularly attractive for visitors who want reliable outdoor weather.

Cairns Weather in September

September is generally one of the driest months in Cairns, although temperatures begin increasing as summer approaches.

The current Visit Cairns climate information lists an average September maximum temperature of approximately 28°C, a minimum around 19°C and an average water temperature of about 24°C. 

Rainfall remains relatively low and humidity is generally much more comfortable than during the wet season.

The weather can feel increasingly warm towards the end of the month.

Clear skies and low rainfall make September particularly useful for planning outdoor activities because there is generally less risk of having an itinerary disrupted by persistent rain.

Is September a Good Time to Visit Cairns?

Yes. September is one of the best months to visit Cairns.

The dry-season weather remains reliable, but temperatures are beginning to warm as spring arrives.

This makes September a particularly good all-round month.

You can comfortably combine reef trips, rainforest tours, hiking, waterfalls, beaches and adventure activities without having to deal with the intense heat and humidity of summer.

The main consideration is that September remains a popular tourism month so forward bookings are highly advisable.

Australian school holidays can also affect visitor numbers, depending on the state and the timing of the holidays.

Booking popular activities ahead of time is recommended if you have fixed dates or particular tours you do not want to miss.

What Should I Pack for Cairns in September?

September is beginning to feel more tropical again, so lightweight clothing should make up most of your luggage.

Recommended items include:

• T-shirts and lightweight clothing
• Shorts
• Long pants
• Comfortable walking shoes
• Swimwear
• Light jumper
• Hat
• Sunglasses
• Sunscreen
• Insect repellent
• Reusable water bottle
• Small daypack
• Lightweight rain jacket (just in case)

A light jacket can still be useful during early mornings and evenings, particularly if travelling into the mountains.

Is Cairns Busy in September?

September remains a popular tourism month.

The combination of excellent weather, school holidays in some parts of Australia and the beginning of spring attracts plenty of visitors.

Popular reef cruises, accommodation and major attractions can become busy.

If you have fixed travel dates or particular experiences you want to book, organising them in advance is recommended.

The region’s large number of attractions means it is still possible to find quieter places, particularly away from the main tourist centres.

Events and What’s On in September

September can be a lively month in Cairns, with markets, cultural activities, sporting events, exhibitions, festivals and live entertainment taking place throughout the region.

Starting in late August, but continuing into September, Festival Cairns has loads of both free and paid events all around the city, with something for everyone.

September is also an excellent month for outdoor dining and exploring Cairns’ restaurants, cafés, galleries and markets.

September Tour Highlights

By September the regions waterfalls are starting to slow down a bit, but there are still may that are spring fed and still flowing well, all the waterfalls on our waterfall circuit never go dry. The Barron Falls run all year and can be viewed from the Kuranda Skyrail & Train.

The Humpback Migration has almost finished, but you may still get lucky with a sighting from a Reef Cruise, but the specialised tours have finished for the season

Why Visit Cairns in September?
