Insulation Installers Penrith

Penrith experiences a humid subtropical climate characterised by long, hot summers and mild to cool, short winters with chilly nights. Spring and autumn bring pleasant weather. Daytime temperatures generally run a few degrees warmer than Sydney, particularly in spring and summer, and night-time temperatures tend to be a few degrees cooler than the CBD throughout most of the year. In some cases, there can be a significant temperature gap of up to 10°C in the summer, primarily due to sea breezes, which have a more significant impact on coastal regions than on areas farther from the ocean, like Penrith.

Occasional frost occurs on winter mornings, mainly due to a mountain breeze and temperature inversion caused by the nearby mountains. Summer temperatures typically range from 18°C to 30 °C, while winter temperatures range from 6°C to 19°C.

Penrith has an average annual rainfall of 719.2mm, significantly less than coastal areas like Sydney Observatory Hill, which records an average annual rainfall of 1212.2mm. This disparity is due to coastal showers not extending inland. Penrith has experienced some extreme temperature conditions, with the highest recorded temperature being 48.9 °C on 4th January 2020. Conversely, the lowest recorded temperature was -1.4 °C on 12 July 2002. Penrith’s hot temperatures are influenced by its inland location, the urban heat island effect (characterised by high housing density and limited tree cover), and its proximity to the Blue Mountains, which can trap hot air.

Penrith enjoys dry and sunny winters, thanks to the Great Dividing Range blocking westerly cold fronts, causing them to turn into warm winds on the leeward side of the range.
