The swell eased back into yesterday morning and early light winds created clean conditions across most spots before a trough brought onshore winds through the day.
This morning conditions are bumpy but workable with 2-3ft of W/SW swell on the Surf Coast and 3-4ft sets to the east. Winds will strengthen from the S'th during the day creating deteriorating conditions.
This week and weekend (Oct 5 - 8)
Later today a new, inconsistent W/SW groundswell is due to arrive across the state, with a peak due tomorrow morning and winds are now looking slightly more favourable for the Surf Coast.
The swell produced XL surf across Margaret River, with it generated by a strong, slow moving frontal progression that fired up in the south-east Indian Ocean on the weekend.
It'll be inconsistent but the Surf Coast magnets should see 4ft sets with 6ft sets to the east, easing through the day. There'll also be some weak S'ly windswell in the mix from this evening's strengthening winds.
The deepening low (sitting off the Gippsland Coast) linked to the strengthening winds will shift to the east tomorrow, swinging winds SW through Bass Strait, but the Surf Coast is likely to see winds shift W/NW and hold through most of the day.
Make the most of this period of cleaner conditions as a secondary trough will push in early Friday morning, bringing strong S/SW winds which are due to ease slightly through the day.
This will spoil our much more significant SW groundswell that's currently being generated south of Western Australia.
We saw a polar low 'bomb' early in the week, dropping over 24hPa in central pressure within 24 hours, and this has resulted in a fetch of severe-gale to storm-force W'ly winds being generated through our south-western swell window.
Satellite observations have picked up core wind speeds of 60kts and the low is now weakening, with severe-gales continuing through our swell window today before breaking down tomorrow.
A large, long-period SW groundswell is due from the low, arriving Friday and building rapidly into the afternoon. The Surf Coast is still on target to reach 6-8ft with 8-10ft sets to the east but with the pesky S/SW-S wind.
Easing, large surf from the 6ft range is expected on the Surf Coast Saturday, 8ft to the east but a stalling high to our west will maintain moderate to fresh S/SE winds. Lighter S'ly winds are due Sunday as the swell continues to ease, likely variable across Phillip Island offering workable options.
A fun, reinforcing pulse of SW groundswell is due on Monday, generated by a trailing front behind the polar low, generating gale to severe-gale W/NW winds across and east of the Heard Island region today, weakening tomorrow.
This should provide inconsistent 3-4ft sets on the Surf Coast magnets and 5-6ft sets to the east Monday morning but with pesky, lingering S/SW winds. Lighter S'ly winds and easing surf may be seen on Tuesday but it won't be until Wednesday that we see winds going N'ly again.
By then the swell will be smaller and back to 2ft+ on the Surf Coast and 3-4ft to the east.
Longer term the outlook is still so/so for the end of the week so make the most of tomorrow.
