Recap

A low point in swell yesterday with clean, warm morning conditions, hotter today with a small lift in inconsistent groundswell across the South West, though under the expected 4-5ft. The swell has lifted a touch more since early but is still slow.

This week and next (Jan 5 - 11)

Today's inconsistent SW groundswell should be reinforced by a secondary, mid-period swell alter today, with no adjustment needed to tomorrow morning's size.

It'll be inconsistent but we should hopefully see 3-5ft sets on the South West magnets, tiny in Perth and Mandurah along with a less than ideal, light to moderate S/SE breeze. Perth and Mandurah should offer a better offshore wind but there'll be no size.

Smaller surf is due into Sunday and an approaching trough will bring early light winds that will shift south-southwest and then west-southwest while strengthening later in the day. This will be as the trough supports the formation of a severe low with it being strongest once moving just off the SW tip of the South West region.

A fetch of severe-gale SW winds will be generated in our close-range swell window, kicking up a rapid, stormy increase in swell through Monday, peaking late in the day before easing rapidly from the S/SW on Tuesday.

Perth and Mandurah aren't due to see any major size as the low forms a little south but we should see building levels of SW windswell from 2ft in the morning to 3ft later in the day across Mandurah, 2ft+ in Perth. Margs should build to 8ft+ through the day but strong SW winds will create poor conditions.

As the low moves off to the east Tuesday winds will unfortunately linger from the S/SW across the South West, but shift SE in Mandurah in Perth but with easing 2ft sets max, dropping from 6ft+.

Wednesday looks a little cleaner with a S/SE breeze in the morning but small, fading swell.

Longer term, more favourable SE winds late next week look to shift S'ly on the weekend as a progression of stronger polar fronts start to fire up from the Heard Island region, squeezing the bottom flank of a high sitting to our west.

This will bring moderate sized+ pulses of swell for later next week and next weekend, coming in around 6ft or so across the South West, 2ft on the sets in Mandurah and 1-2ft across Perth but more on this Monday. Have a great weekend!
