A trough has moved inland and a mid-latitude low is approaching the SW of the state, bringing an onshore flow that is likely to tend NW to N through tomorrow. The low then crosses the South-West land division on Wed, bringing several wind changes through the day as it moves inland.
Next week still looks like being marred by a constant onshore flow until Thursday as a node of the long wave trough directs weak fronts into the SW.
The low has now passed through the area and is weakening in the Bight, with a long trailing fetch of W’ly winds bringing continued onshore conditions as local storm surf slowly eases back through tomorrow.
The first blast tomorrow will be increasing N/NW windswell, with increasing N’ly winds tending NW through the a’noon and potentially becoming gale force, especially on the Bunbury to Perth stretch.
Easing surf with deteriorating conditions over the weekend, worsening next week as a severe, slow moving mid-latitude low moves in from the west.
Make the most of the coming cleaner conditions and fun swell as next week will be mostly a write-off thanks to a slow moving and high-riding mid-latitude low.
Plenty of swell and with initially poor conditions across the South West, improving later week.
There's lots of swell still on the cards for this period but it's dealing with the local winds which is the main issue.
Plenty of options for a surf as we head deeper into spring across the state.
We've got a fun swell for tomorrow with workable winds, cleaner Wednesday while the swell for late in the week has been downgraded and delayed a little.
