Cairns in May

May is one of the most appealing months to visit Cairns. The tropical wet season is generally over, rainfall rapidly decreases, humidity becomes more comfortable and the weather begins settling into the dry-season pattern that makes Cairns such a popular winter destination.

The landscape is still wonderfully green after the summer rains, while the Great Barrier Reef remains warm enough for comfortable snorkelling and diving. The rainforest, waterfalls, beaches and mountains can all be enjoyed without the intense heat and humidity of the summer months.

May also marks the beginning of the cooler season in Tropical North Queensland. Days remain warm and tropical, but mornings and evenings can feel noticeably fresher, particularly in the rainforest and higher areas around Kuranda and the Atherton Tablelands.

For visitors looking for a combination of warm weather, increasingly reliable sunshine, lush scenery and fewer crowds than the peak winter months, May can be an excellent time to visit Cairns.

What is Cairns Like in May?

May is generally warm, comfortable and considerably drier than the preceding months.

It is often regarded as the beginning of Cairns’ dry season, although the transition is gradual and some rainfall may can still occur, particularly early in the month.

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

Compared with January and February, the difference can be quite noticeable. Humidity is generally lower, temperatures are more comfortable and there are usually longer periods of settled weather.

You can generally expect:

• Warm, comfortable days
• Cooler mornings and evenings
• Lower humidity
• Decreasing rainfall
• Increasingly clear skies
• Lush green rainforest
• Warm ocean temperatures
• Excellent conditions for outdoor activities

May provides an excellent balance between tropical warmth and comfortable outdoor conditions.

Cairns Weather in May

May is one of the months when Cairns’ weather starts to become particularly attractive for visitors.

The current Visit Cairns climate information lists an average May maximum temperature of around 27°C, a minimum of approximately 20°C, and average water temperatures around 26°C. 

Rainfall is considerably lower than during the wet season.

While showers are still possible, extended periods of wet weather become less common as May progresses.

The lower humidity is arguably one of the biggest improvements. Visitors who find Cairns’ summer humidity uncomfortable will generally find May much easier for walking, sightseeing and outdoor activities.

The nights can feel surprisingly cool compared with the tropical summer, particularly if you are camping or staying in the mountains.

Is May a Good Time to Visit Cairns?

Yes. May is an excellent month to visit Cairns.

It combines warm weather with the beginning of the dry season and generally lower visitor numbers than the busiest winter months.

The rainforest remains green after the wet season, while the weather is becoming increasingly suitable for long days outdoors.

May is also a particularly good month for visitors who want to combine several different Cairns experiences.

You can spend a day on the Great Barrier Reef, another exploring the Daintree, another visiting Kuranda and another hiking or swimming in the rainforest.

The main consideration is that the water and evenings are cooler than they were during summer.

For most visitors this is a small trade-off for the much more comfortable daytime climate.

May Tour Highlights

While the wet season is officially over the rainforest will still be very lush and green and the region’s waterfalls will still be pumping tours such as a visit to Kuranda or the Atherton Tablelands will show these waterfsalls’s at their finest. 

May is also a perfect month to check out the Great Barrier Reef. It’s also a perfect time to go whitewater rafting on the Tully River as the temperature’s still warm. 

What Should You Pack for Cairns in May?

May requires slightly more variety in your packing than the summer months.

Recommended items include:

• Lightweight shirts and shorts
• Long pants
• Comfortable walking shoes
• Swimwear
• Light jumper or jacket
• Lightweight rain jacket
• Hat
• Sunglasses
• Sunscreen
• Insect repellent
• Reusable water bottle
• Small daypack

If you are camping or spending time in the mountains, bring an additional warm layer.

Early mornings and evenings can feel quite cool compared with the tropical summer.

Is Cairns Busy in May?

May is generally less busy than the peak winter months of June, July and August.

This can make it an attractive time for visitors who want the benefits of the dry season without the largest crowds.

The region’s major attractions and tours remain available, but accommodation and reef trips can generally be easier to organise than during the busiest holiday periods.

As May progresses and the weather becomes increasingly reliable, visitor numbers tend to increase.

Events and What’s On in May

Cairns has a regular calendar of markets, cultural events, sporting activities, exhibitions, live entertainment and community events throughout May.

Individual event dates change from year to year, so visitors should check the current Cairns events calendar before travelling.

May is also a good time to explore Cairns’ restaurants, cafés, markets and galleries, particularly if you want to combine outdoor sightseeing with the city’s food and cultural experiences.

Why Visit Cairns in May?

May is one of Cairns’ best-kept secrets.

The worst of the wet season has generally passed, but the rainforest is still beautifully green.

Temperatures are warm rather than oppressive, humidity is lower, rainfall is decreasing and the Great Barrier Reef remains warm enough for comfortable water activities.

It is also a great month for hiking and exploring the Daintree because cooler temperatures make long days outdoors much easier.

For visitors who want good weather without the busiest part of the winter tourism season, May can be an outstanding choice.
