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

This week and weekend (Mar 13 - 18)

Today's initial strong increase in SW swell will be followed up by a secondary pulse tomorrow, generated by a good fetch of W/SW gales trailing the initial front that produced today's surf.

We should see Clifton continue around 3ft tomorrow, easing off slowly into the afternoon, while we'll continue see 2-3ft waves Wednesday morning from an additional fetch of W'ly gales pushing in from under WA today.

Winds look great each morning with a W/NW breeze tomorrow, NW Wednesday and then early W/NW Thursday as the swell bottoms out.

As touched on last week, we've got a much larger swell due late in the week, owing to a vigorous polar low forming south-west of us tomorrow evening.

A tight but intense fetch of severe-gale to storm-force SW winds will be projected ideally up towards us through Wednesday and Thursday before clearing off to the east Friday.

This will result in a large powerful long-period SW groundswell for Friday, though with an increase due through Thursday to 3ft+ later in the day, peaking the next morning in the 5-6ft range across Clifton.

Winds are due to tend variable Friday morning in the wake of the low with E'ly breezes into the afternoon as the swell gradually eases.

This easing trend will be slow owing to the low still aiming a fetch of SW gales through our southern swell window Thursday evening.

Saturday should still see good 3ft sets with offshore winds ahead of sea breezes.

Longer term we've got another strong node of the Long Wave Trough due to move in next week, bringing large surf mid-next week, but more on this Wednesday.
