Hot dry summer with cool winter

Where is it?

This is the largest climate zone, extending from the west coast to the inland slopes of the Great Dividing Range (see chart). Examples are Alice Springs, Mildura and Perth (except for its beachside suburbs).

What's it like?

In this climate, summers are hot and it seldom rains. Winter days may be cool or warm, but the winter nights are cold, especially in inland locations. The air is dry, there is little cloud and sunshine is intense; glare is a problem. There is a big temperature difference between day and night.

House design aim:

The primary aim is summer cooling but solar heat gain in winter is also necessary. Some trade-offs between summer cooling and winter passive heating may be necessary. Click here for design tips for indoor comfort in this climate.

Suitable building block:

Solar access is required in winter.
