A new long period groundswell is then expected to rebuild into Wednesday, sourced from an intense polar low skirting the ice shelf on Sunday.

As stated on Wed, the Indian Ocean is quite active with a long fetch of W’ly gales currently SW of the state and moving E. That will supply reinforcing pulses of SW swell later in the weekend into Mon .

Weak high pressure is in the Tasman with a modest tradewind fetch in the Coral Sea with another weak high moving into the Tasman in it’s wake. Trades perk up today into tomorrow suggesting a small bump in size over the weekend into Mon before easing early next week.

SW gales push through Bass Strait and off the Far South Coast Sun night and into Mon with the bulk of the frontal winds now likely to reach Coffs around 7am, Byron by lunch and the border around school pickup
