Weather in Blue Mountains Guide: What to Expect Each Season

The Blue Mountains is one of those magical places that looks beautiful all year round. But depending on when you visit, your experience can feel completely different, from misty mornings in winter to vibrant wildflowers in spring.

So, what’s the weather really like in the Blue Mountains? What should you pack? And when’s the best time to go? Let’s break it down by season so you can plan your adventure like a local.

If you haven’t already, check out our Blue Mountains tours. They run year-round and are designed to help you explore the best of the region, no matter the season.

Temperature

Average temps: 15°C to 30°C (59°F to 86°F)

Summer brings warm weather, long daylight hours, and lush green scenery. It's the perfect time for bushwalks, scenic lookouts, and soaking up panoramic views under blue skies. But keep in mind, temperatures can still vary, especially in shaded forested areas or higher elevations, so it’s smart to pack layers.

What to pack:

Light, breathable clothing
A hat and sunscreen
Plenty of water
A light jacket for cooler spots or changing conditions

Local tip: This is also peak holiday season in Australia. If you’re hoping to avoid the busiest crowds, book a late start Blue Mountains tour to enjoy a more peaceful experience.

Temperature

Average temps: 10°C to 25°C (50°F to 77°F)

Autumn in the Blue Mountains is something else. The eucalyptus forests start turning golden, and the valleys come alive with color. The air is crisp but not too cold, making it an ideal time for walking trails like Wentworth Falls or the Grose Valley.

What to pack:

Layers you can add or remove throughout the day
A windbreaker or raincoat (just in case)
Comfortable walking shoes with grip

Why autumn is a favorite: Fewer tourists and milder temperatures make this one of the best times to truly enjoy the region without feeling rushed.

Temperature

Average temps: 0°C to 15°C (32°F to 59°F)

Yes, it gets cold up here. But winter is also when the Blue Mountains feels its most dramatic. Morning mist blankets the valleys, waterfalls run strong, and you’ll get a whole new perspective of places like Echo Point or the Three Sisters. On especially chilly days, there’s even a chance of snow in higher elevations.

What to pack:

Warm layers, including a jacket and scarf
Gloves and a beanie
Closed-toe shoes or boots
An extra pair of socks for good measure

Pro tip: A warm meal hits differently in winter. Our tours include stops at local mountain eateries where you can cozy up with delicious seasonal fare. If you’re wondering what’s included, visit our FAQs for the full scoop.

Temperature

Average temps: 10°C to 22°C (50°F to 72°F)

Spring is when the Blue Mountains comes alive again. Wildflowers start blooming, waterfalls are still flowing from winter rains, and the weather is perfectly mild. It’s also the season where you’ll likely spot more native wildlife, like wallabies and lyrebirds.

What to pack:

A mix of light and medium layers
A camera or smartphone for the wildflower shots
Walking shoes for the trails (some might be muddy from recent rains)

Spring highlights:

This is a popular time for nature photographers, especially with our VIP Kangaroo and Koala Encounter, where the light is ideal and the animals are active. Great for family travelers or anyone looking for a more immersive wildlife experience.

Honestly, there’s no bad time to visit the Blue Mountains. Each season brings something special, whether it's autumn colors, winter mist, spring blooms, or summer sunshine. What matters most is picking a time that matches your style of travel.
