Now that it is starting to cool down, here is a good read.

Any time your body is losing more heat than it can generate, you are at risk of hypothermia. How big is the risk, well that depends on how quickly you are losing heat. Interesting, most hypothermia cases develop in air temperatures between 0°C and 10°C degrees (32° - 50°F). Yep, a typical Tassie winter day. The big negatives are wet (rain, sweat, or water) and wind.
Hypothermia remains a significant risk and bushwalkers are one of the high-risk groups. So, knowing how to prevent it, knowing how to recognise it and knowing how to treat it are probably important. (
