Insulation Installers Blue Mountains

The expansive Blue Mountains region covers 1,032,649 hectares (2,551,730 acres) and was listed on the World Heritage List during the 24th Session of the World Heritage Committee, which convened in Cairns in the year 2000.

The Blue Mountains have a rich historical significance due to their mountainous terrain, which marks a substantial part of Greater Sydney’s western boundary. Situated approximately 50km west of the city centre, near Penrith, they share borders with Sydney. While the Blue Mountains are just one part of the extensive mountainous landscape associated with the Great Dividing Range, their specific boundaries were officially defined in 1970. These boundaries include the Nepean and Hawkesbury rivers to the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, they are located within the Sydney Basin.

The climate in the Blue Mountains varies with elevation. At an elevation of around 1,010m, Katoomba experiences a summer with an average maximum temperature of approximately 22°C. Occasionally, temperatures can reach into the 30s°C, but it’s not uncommon to see maximum temperatures staying in the teens, especially when influenced by east coast troughs. Summer nights usually remain in the teens, sometimes dropping into single figures.

In winter, daytime temperatures in Katoomba typically hover around 10 to 11°C, with clear nights dropping to about -1°C, and cloudy nights stabilising at 3 to 4°C. While it’s rare, temperatures can occasionally dip to -3°C or lower. Generally, the coldest air settles in the valleys during calm, clear nights. The Blue Mountains is not known for exceptionally cold mornings compared to other areas on the Central Tablelands, such as Oberon, Bathurst and Orange. Snowfall occurs in the region two to three times a year.

On an annual basis, the Upper Blue Mountains receives an average rainfall of about 1,050mm, often accompanied by numerous misty days.
