@corrineb any chance you could implement the BOM Australia’s feels like formula for us Australians?

AT = Ta + 0.33•ρ − 0.70•ws − 4.00

and

ρ = rh • 6.105 • e(17.27*Ta/(237.7+Ta))

where:

• AT is the Apparent Temperature in oC;
• Ta is the Dry bulb Temperature in oC;
• ρ is the water vapor pressure (hPa);
• ws is the wind speed (m/s) at 10 meter above the ground;
• rh is the Relative Humidity (%).

Reference here: http://www.bom.gov.au/info/thermal_stress/#atapproximation and there’s a simple calculator here: https://www.vcalc.com/wiki/rklarsen/Australian+Apparent+Temperature+(AT)

@GaryFunk I actually found another post which is the same… Steadman Apparent Temperature (Australian Apparent Temperature)

Ok I have written a php script that gets the Australian Feels Like temperature for those who get coding…

\$Ta = Dry bulb temperature (°C)
\$rh = Relative Humidity [%]
\$ws_kmh = Wind speed (km/h)

``````<?php
function getAUApparentTemp (\$Ta,\$rh,\$ws_kmh)
{
\$e = \$rh / 100 * 6.105 * exp ( 17.27 * \$Ta / ( 237.7 + \$Ta ) );
\$ws = \$ws_kmh/3.6;
\$AT = \$Ta + 0.33*\$e - 0.70*\$ws - 4.00;
return round(\$AT,1);
}
?>``````
