Recap

Record breaking temperatures and not much in the way of swell for the Christmas weekend. Also some unfortunate loss of property with fires flaring up across the state.

A small lift in swell was seen through the day yesterday but it wasn't overly sizey, cleaner this morning and to a fun 3-4ft on the sets.

Fun clean sets this AM

This week and weekend (Dec 28 – Jan 2)

The small pulse of swell seen over the past 24 hours will ease into tomorrow morning leaving very small waves across the South West, tiny to flat to the north. Conditions will be clean early with a fresh NE breeze, shifting N/NW across the South West ahead of sea breezes.

Our secondary pulse of weak, mid-period SW swell for the week is due to arrive later tomorrow but peak Wednesday morning across most locations. This swell will be smaller than the current swell and only come in at an infrequent 3ft+ across the South West if we're lucky and tiny to the north again.

Winds aren't ideal and are due to be S/SE early and light across the South West before freshening from the S/SW during the morning and then SW into the afternoon. Perth and Mandurah will be cleaner but tiny to flat.

Gusty S/SE winds will create average conditions as the swell fades Thursday, smaller Friday with similar S/SE winds.

We then look at a weak frontal progression firing up to the south-west of us into the end of the week.

It won't be overly strong resulting in a moderate sized, mid-period S/SW swell event, with fetches of strong W/SW tending SW winds being projected through our southern swell window.

This will only favour the South West swell wise with Perth and Mandurah due to remain tiny. The first pulse of swell should arrive late Saturday but peak Sunday to 4-5ft+ across the South West, 1-1.5ft to the north.

The easing trend into Monday will be slowed by weaker, reinforcing frontal activity, keeping maintain 4ft sets through the day, easing from 3-4ft on Tuesday.

Winds will be less than favourable as the fronts keep a high sitting to our west, directing strong S/SE-SE winds across the state Sunday morning, becoming even stronger from the S/SE into the evening, fresh SE on Monday morning as the swell eases.

Longer term the outlook still remains void of any major swell generating systems but check back here Wednesday for an update on when next the swell might get above 6ft.
