Roaring Forties moving south - impact on swells to Southern Aus?

Well they didn't specifically mention the orientation, so it could be good. Swell still being sent poleward, but less blown out surf...?
Also, 1000 years is a short time in climate change. So the data is not bad or wrong, but limited.

For the purposes of recreational surfing, I don't think it means anything at all.

Climate trends are really hard to equate to surf potential, because there are so many variables that come into play.

However the basis of this articles related to the Southern Annular Mode (SAM) of which there are short to medium term forecast possibilities for locations that have less erratic local variables. For example, Indo, the South Pacific and Central America.

Cheers!

Last time i heard of this research ( AGW related ) ,
they were saying that the roaring forties would retract Sth and also strengthen , or see far more Westerly component and less SW NW component ( ie less fronts reaching as far Nth ) .....

So i would say in that context it could be good for exposed spots that might see better conditions for longer in the Autumn- Winter and Winter - Spring transitions .

Mind you there's a lot of Hypothesis in there ! ( the research that is ) ....

Yeah Southey, that's what had in mind. Except I wrote poleward, but meant equator-ward.
