Blue Mountains Weather – What to Expect Year Round

Planning a visit to the Blue Mountains? One of the most common questions we get asked is: “What’s the weather like in the Blue Mountains?” Whether you're chasing misty mornings, crisp winter air, or vibrant spring blooms, understanding the climate can help you plan the perfect stay.

Here’s everything you need to know about Blue Mountains weather, including average temperatures, rainfall, snowfall, and the best time to visit.

The Blue Mountains climate is generally cooler than Sydney’s, thanks to its higher elevation. Temperatures vary by season but tend to sit several degrees lower than those in the city.

• Summer (Dec–Feb): Average highs of 19–22°C, with cool evenings

• Autumn (Mar–May): Mild days and cool nights, perfect for hiking

• Winter (Jun–Aug): Chilly with average lows around 5°C – bring a coat!

• Spring (Sep–Nov): Fresh mornings and sunny days, ideal for outdoor exploring

Located in Wentworth Falls, Glen Isla enjoys the fresh, crisp air typical of the upper Blue Mountains.

The rainiest months in the Blue Mountains are usually February, March, November, and December. The upper mountains—where Glen Isla is located—tend to receive more rainfall than the lower regions, which adds to the lush beauty of the local gardens and forests.

If you love dramatic mist and lush green surroundings, a rainy day in the Mountains can be downright magical.

The Blue Mountains is spectacular at any time of year and in any weather.

Yes... but not often. While snowfall in the Blue Mountains is possible during winter (particularly in areas like Blackheath and Mount Victoria), it’s fairly rare in Wentworth Falls. In the 12 years we’ve hosted guests at Glen Isla, we’ve only seen significant snowfall three times. If you’re lucky, you might catch a light dusting—perfect for a wintery photo op!
