This week and weekend (Aug 14 - 19)

Today’s Forecaster Notes are brought to you by Rip Curl

The small pulse of W/SW swell seen yesterday afternoon and this morning will fade into tomorrow, but a strong front passing under us today, generating W'ly gales looks to produce a tiny 1ft of W/SW swell for tomorrow with W/NW tending NW winds.

This is then due to fade through Wednesday with the next increase in size due through Thursday and Friday.

A vigorous mid-latitude low will move in from the west and dip south-east across us on Wednesday but winds will be W/NW in direction with no new swell expected through the day.

A better aligned polar fetch of S/SW winds is expected to develop south of us on Wednesday, generating a new S/SW swell that should build later Thursday and peak Friday.

Some small weak mid-period W/SW swell will also be in the mix from the backside of the mid-latitude low pushing across us Thursday.

This should provide 2ft sets on Thursday with the S/SW energy possible kicking a little larger late in the day, peaking Friday to 2ft to nearly 3ft.

Winds on Thursday look good through the morning with a W/NW breeze possibly swinging W/SW temporarily before tending back W/NW later and then holding all day Friday from the NW.

A low point in swell is expected early Saturday but through the day and more so into Sunday and Monday, a strengthening and slow moving polar front is expected to develop across the state, bringing strong to near gale-force S/SW winds.

This fetch will extend well south of us but without too much strength, resulting in a building S/SW windswell Saturday afternoon as it pushes across us, increasing further Sunday as a better fetch of S/SW winds are projected into us.

Winds will be onshore but the size likely reaching 3-4ft later Sunday and easing Monday with much cleaner conditions. We'll have a closer look at this on Wednesday though.
