Weather and safety.

Cold nights, warm days and a lot of wind. Here is what to expect on the Mundi Mundi Plains in August, and what to pack.

What to expect

Two climates in one day.

August in the outback means bitterly cold nights and mornings, and gloriously mild afternoons. The Bash runs over three days and nights, so you will get the full range.

It is also open country. There is nothing to stop the wind out on the Plains, so what you pack, and how you set up camp, matters.

Heads up

It gets windy. Tie everything down.

The Mundi Mundi Plains site sits beside a wind farm, and that is no coincidence. Before you head to the concert, secure your awnings, camp chairs, rugs and anything else that could blow away.

Take it seriously. What is not tied down may not be there when you get back.
