Fun surf this morning

This weekend and next week (Oct 14 - 20)

Today's pulse of W/SW groundswell was generated by severe-gale N/NW winds at the head of a polar low, with trailing, stronger gale to severe-gale W/SW winds due to generate a stronger SW groundswell for the weekend.

The groundswell is due to arrive tomorrow morning and build towards a peak into the afternoon with 6-8ft sets on the South West magnets 2ft+ in Mandurah and 2ft across Perth.

The swell is due to ease back from 4-6ft in the South West and 2ft Mandurah with 1-2ft sets across Perth, smaller Monday.

Local winds will take a shift back to the SE tomorrow morning, strong and tending more S/SE through the day.

Sunday looks cleaner with an E/SE offshore, giving into weaker and slightly later sea breezes.

Into Monday as the swell fades, fresh E/NE tending N/NE winds are due, weaker N'ly into the evening.

As touched on in the updates earlier this week, there's nothing significant swell wise on the cards for most of next week, with a moderate sized lift in mid-period W/SW-SW swell due Thursday/Friday next week.

The source is a persistent but weak frontal progression moving in from the west, bringing a kick to 4-6ft in the South West, 2ft Mandurah and 1-2ft across Perth. Winds on Thursday as the swell fills in look gusty from the SE, with Friday seeing more favourable E/NE winds. We'll confirm this on Monday though. Have a great weekend!
