Late This Week In NSW: Offshore And Pumping – Surfline.com Surf News

Model runs are lending increasing weight to the prospect of good to epic conditions opening up across the NSW coast later this week.

The early stages of this event are already falling into place as an upper-level low and associated surface trough deepen over the NSW interior. The system is forecast to move quickly northeast across the state before shifting off the southern Queensland/northern NSW border on Wednesday.

This means an expansive east to NE fetch across the Tasman Sea, gradually strengthening as it feeds into the lows eastern and southern sectors. Wind-speeds are pretty light through this early phase, thus the early trend in east swell may not break any records, but it should offer up surf in the three to four foot range across southern Queensland and NSW during Thursday, with scope for more size into the afternoon/evening.

As the trough and embedded low drift south, roughly parallel to the NSW coast, a stronger, 30-35 knot ENE fetch should push on an already active sea-state, driving deepwater seas and swell to peaks of 15-20 feet later Thursday.

That sea-state will be aimed more directly at the southern half of the NSW coast. With the upper boundary for the prime swell-window loosely positioned around the Hunter region, all signs point to Friday as the day to be targeting the peak of this event as it kicks in and around Sydney, Newcastle, and the South Coast.

The swells arrival looks like coinciding with mostly favourable, cross-offshore winds as the low moves south on Friday, pulling winds around from the SSW to the W/SW, opening up all manner of pumping conditions as the bulk of mid-period easterly swell peaks throughout the morning.
