Freshening NW winds and temporarily small surf at Victor on Thursday morning will precede a gusty SW change during the day, associated with the first in a series of strong fronts push across the region, tied in with an amplifying Long Wave Trough. 

A smaller E swell will continue into the new week and with winds remaining mostly offshore there'll be waves to be had. 

A polar low developing off the ice shelf on Sunday (well below SA) is better positioned for a swell increase across the South Arm.

Sunday is still looking very good across the region, as winds become light NW in the morning, freshening gradually through the day.
