Why a 35-degree day can 'feel like' 40 degrees
As summer tightens its grip, it is important to remember that there can be a big difference between the temperature, and how hot you're actually going to feel outside.
Temperature readings indicate what the air temperature actually is, as taken by a thermometer.
But, as Bureau of Meteorology senior meteorologist Angus Hines explained in a video earlier this year, there's another measure of what it's like outside - the "feels like" temperature.

"The 'feels like' temperature gives you a better idea of how you might feel in the outdoors," he said.
It's measured by two key factors.
First, Hines said, is wind.
Strong winds can strip the body of the very thin layer of warm air people generate with their own body heat.

So high winds can make it feel cooler.
The other factor is humidity.
High humidity takes away our ability to sweat, and thereby cool down.
This summer, people are advised to take note of both the temperature and the "feels like" temperature to be sure they're prepared accordingly for whatever they plan to do outdoors.
