What's the weather like in the Blue Mountains?

When you're planning your trip to the Blue Mountains it's important to note that you can go at any point throughout the year however there may be limited recreational activities available to do depending on what time of year you travel in.

For example, the months with the highest rainfall in the Blue Mountains are between February and March, and between November and December so visiting the mountain's peaks during this time is not recommended. This is due to the limited outdoor activities available, as hikes and other tours become riskier and unsafe to carry out during wet weather periods. 

Having said that, there isn't a specific 'best time' to visit the Blue Mountains with everything depending on your own travel plans and what you find the most enticing about the area. 

What's the climate like in the Blue Mountains? 

The climate in the Blue Mountains can vary depending on where in the Blue Mountains you are. In the canyons and valleys, the climate is a little different to that of the climate in the mountain peaks. The Upper Mountains see more of a lower temperature on average while the Lower Blue Mountains enjoy a warmer climate with 16°C being the average during the winter months, and 29°C in the Summer months.

Snowfall is quite uncommon on the Upper Blue Mountains despite having a reputation for it, with only about 5 days out of the year that will actually see snow.
