These small lows may move north, then east and finally south or may coalesce in a more classic Tasman Low or ECL variant. With so much uncertainty still around be prepared for major revisions as we move through the week. This is a nightmare to forecast!

A very unstable, dynamic synoptic chart this week with a large high (1034hPa) moving from the Bight through Victoria, with a coastal trough deepening off the Mid North Coast on the leading edge of the high directing very moist onshore winds across Central NSW, extending up into the sub-tropics.

Tuesday will start to build surf size, originating the fetch trailing Monday’s front. However, the origins of this swell will go back five or six days - this system has actually been taking shape from a position south of Africa on Wednesday, before moving eastwards through the southern Indian Ocean.

At best, we have a brief window of light winds early Saturday morning, and this will be the only window of opportunity to surf down south.
