Recap
Poor conditions for the weekend with strong onshore winds to kick off Saturday along with easing levels of swell, improving a little into the afternoon as winds eased. Yesterday was then poor with a shift in winds to the south-east with a couple of options to the east for the desperate.
This morning is much better with a mix of easing SE windswell on the Surf Coast and new mid-period SW swell to the east, coming in at 2ft and 3ft+ respectively. Conditions will remain favourable for the beaches for most of the day, with winds tending E/SE-E later afternoon.
This week and weekend (Nov 7 – 12)
The coming week is flukey wind and swell wise, with the exposed beaches being the pick when winds are favourable and offshore.
Tomorrow morning will be another fun one for the beaches, though size wise the swell will be a touch slower and smaller and to an infrequent 2ft on the sets across the Surf Coast magnets with 3ft sets to the east.
An E/NE-E wind will favour the beaches to the east, tending NE into the early afternoon and then variable towards the evening as a SW change moves in across the west.
Winds look to revert back to the N/NE on Wednesday morning, light NW to the west but a trough will bring a S/SW change later morning to the west, pushing further east into the afternoon.
At the same time as the trough and change arrive, a new mid-period SW swell is expected to fill in, generated by a polar frontal system that's currently south of Western Australia.
Fetches of strong W/NW winds should generate a small bump to 2ft to occasionally 3ft on the Surf Coast magnets and 4ft+ to the east later Wednesday, holding Thursday morning.
Thursday's winds are tricky with a variable breeze likely on the Surf Coast in the morning, light S/SW-S to the east, freshening through the day.
Friday morning should be cleaner but with small, fading levels of swell back from 2ft on the Surf Coast on the magnets and 3ft to the east.
Moving into the weekend, the swell will reach a low point on Saturday as freshening S/SW winds develop thanks to a high sitting under Western Australia, extends an arm out to the east while polar fronts squeeze its south-eastern flank, under Tasmania.
This will see S/SW winds strengthening further Sunday and persisting early next week, writing-off the surf for the entire weekend/early next week while spoiling a new, moderate sized mix of mid-period W/SW-SW swells.
There'll be no lack of size thanks to the polar activity generating healthy swells but the local winds are the main problem, with periods of lighter W'ly winds on the Surf Coast a possibility through early-mid next week. We'll have a clearer idea on this Wednesday and Friday.
Comments
So it’s polar fronts combining with the Highs that keep giving us these persistent southerlies?
More so the blocking and stubborn nature of the highs in the Bight and under Western Australia. Brings up southerly winds on the high's eastern flank.
Stubborn is one word for it!
But the fronts are causing those isobars to be so tightly packed?
Troughs and fronts.
Thanks mate.
Yep. Starting to irritate.
Was a good little reprieve this morning.
We had a good autumn and winter ( 2023 ) of Surf with swell and favourable winds in the W.P. area. Spring is a bit of a non event for surf IMHO.
Has BoM done a Celsius recalibration? Is 20 the new 40?
Rather localised
Just checked the radar. Sure is.
This morning looks very active!
Last night every couple minutes from around 1 to 3 am in Melbourne there was this crazy lighting with no thunder and no clouds in the sky. What is this caused from and what is it called? Multiple times camping around Port Campbell I've seen a similar thing in this same weather but its so trippy, always thought it couldve been some big industry thing down there lighting up the sky at night.
Flashes at about 3, and a quick look at the radar showed very localised thunderstorms at a distance from us, further down GOR and further to east. Big gaps between each cloud so there would be places you probably couldn't see them from. The clouds were moving from a NW direction to the SE. Looking out the windows the thunderclouds looked fluffy and amazing, I didn't see any big anvil tops but they were very tall in the clear, bright night sky. I guess unstable, moist air, whatever it was I love those conditions.
Actually, Craig or Ben can you describe what kind of air mass and synoptic creates those unreal conditions?
(We did have a solar storm with two apparent pulses, too...)
Sick, yeah nothing to do with the solar storms.
Just atmospheric instability thanks to a deepening inland trough line extending from south of Victoria to NSW and then Qld.
Drawing in heat from the north-east while cooler south-west winds sit to the south-west. A bit of moisture in the air as well with higher than normal dew points.
Cheers Craig. Awesome pics there Dbut - that was near Lorne! Oh wow. For one last year we tried to see it and went up to Bells but only cameras could pick it up, this one looks spectacular!
Just out of interest:

Kp 7 which is pretty high, and uncommon.
With these onshore/small swell conditions i’m getting flashbacks and post-trauma from our great surfcoast surf drought of recent years.. i hope we’re not heading into another one of those nightmares
Sea fog creeping in with the trough this morning. It's taken over the Surf Coast and northern end of the peninsula, Rye is next..
Fog is just lifting at 12:45, weird feel on the beach this morning, enough sun sneaking through to generate mist rising from the sand.
With the change.
