In that case, you should know something very important. That chart you showed was of wave heights and direction- not winds. Most of those waves are developed in the southern oceans long fetch.. That intense low will have wind
strengths in a similar but not identical direction in some places But the wind
and waves would be opposing in the bottom half of that image.. Low pressure air cycles clockwise in the southern hemisphere, but a part of that cycle is inwards too.
On the assumption there was a low that looked like that, have a look at the easterly end of the red section- directly under Adelaide. The wind there would be almost Northerly-abeam to the Swell. Thus creating its own localized sea state on top of the swell so to speak. This is why weather
forecasters talk about Swell and Sea as two different things.
Move that whole thing 500m east and it would get worse in bass Straight as the Swell hit the shelf then meets the EAC creating the washing
machine its known for.
