Recap

Pumping waves across the Surf Coast yesterday and this morning with strong levels of W/SW swell to 4-5ft, with larger messier waves on the Mornington Peninsula.

Back to back mid-latitude fronts generated this swell and we'll see the surf starting to ease through this afternoon with average winds.

This weekend and next week (Feb 17 – 23)

In the wake of the strong mid-latitude frontal activity through our western swell window, we've now got a stalling and strong low directly south-west and south of us.

Last night a good fetch of strong to gale-force W/SW winds were persisting in our south-western swell window, with stronger severe-gale to storm-force SW winds in our southern swell window.

We're due to see these winds persist this morning while starting to move north-east, out of our swell window this afternoon.

We can expect moderate amounts of SW groundswell to persist tomorrow, with a new stronger S/SW groundswell from the storm-force winds, providing solid 4-5ft sets most of the day on the Surf Coast and 6ft+ waves on the Mornington Peninsula.

Winds are looking great for the Surf Coast and light offshore from the NW, tending W/NW ahead of possible sea breezes and then a fresher mid-afternoon SW change. Locations east of Melbourne may see lighter N winds at dawn before swinging more NW.

Into Sunday both the SW and S/SW energy will ease likely from the 3ft+ range on the Surf Coast and 4-5ft+ on the Mornington Peninsula as winds tend more variable. This should create favourable conditions for most spots ahead a S/SE change associated with a surface trough moving in from the west.

This trough will be the catalyst for a poor run of winds into early next week as it stalls off the southern NSW coast and strengthens while a strong high moves in from the west.

As a result moderate to fresh SE winds will strengthen from the E/SE on Monday, creating poor conditions and a building SE windswell on the Surf Coast, mixed in with a new S/SW groundswell.

The groundswell will be produced today and tomorrow by a final polar front firing up on the backside of the low to our south, projecting a good fetch of strong to gale-force SW winds through our southern swell window.

The Surf Coast should see 3-4ft sets, with 6ft surf on the Mornington Peninsula, but with those poor winds.

Winds will swing a little more east into Tuesday but remain gusty with a poor mix of easing S/SW swell and SE windswell on the Surf Coast and peaky workable waves in protected spots east of Melbourne, likely easing from 3-4ft.

Much cleaner conditions should be seen Wednesday with a NE wind, but with no new swell even the beaches east of Melbourne will be small. Longer term we may see some new W/SW swell late week but with onshore winds. More on this Monday. Have a great weekend!

Lorne still offering some tidy waves for the early session.
