Gales exiting Bass Strait today will see a first pulse of weaker refracted S swell early tomorrow but the real juice is being generated by a deeper fetch of severe gales tracking from 55S up to 40S, into the Tasman sea through today and early tomorrow.
Favourable winds and lots of surf for the South Coast over the coming period, less so for the Mid until early next week.
Today's large mix of building swells will ease through tomorrow with less than ideal winds, cleaner Wednesday but much smaller. There are options for the beaches late week with a new, inconsistent westerly groundswell.

Features of the Forecast (tl;dr)
Recap
Small amounts of NE windswell in the 1-2ft range provided some just rideable surf Thursday. Swell from this source has eased back but with a few tiny waves available at NE facing beaches.
Lots of surfing options over the coming days with varying winds and strong swells.
There's been a local improvement to conditions on the weekend and early next week looks good until onshore winds and fronts come back late next week.
The deeper southern fetch tied to the polar low then fires up and aggressively tracks almost due north towards Tasmania with gales and severe gales extending up to almost Tasmanian latitudes later Mon.
The good run of swells and conditions will continue into the weekend though the windows on the Mid will become smaller.
This is another impressively large and complex system, with a double headed low centre forming in the deep southern ocean around 60S and a more proximate cold front fetch expected to push NE to be adjacent to Tasmania through Monday morning.
Plenty more surf and swell to come, cleanest on the weekend and deteriorating through next week when largest.
