Recap

Yesterday was generally poor with onshore winds across all locations that slowly improved across the metro regions during the day but with weak levels of local windswell that strengthened later in the day.

Today is a complete contrast with a peak in large W/SW groundswell under offshore winds and sunny skies. It’s pumping from Margs to Perth and beyond with 10-12ft+ sets in the South West, 3-4ft across Mandurah and 3ft in Perth. Winds will remain offshore all day so make the most of it.

Some XL sets in the mix today

This week and next (Jul 4 - 13)

Following today's peak in large W/SW groundswell energy, we’ve got some good reinforcing pulses of SW energy on the cards for the coming days. The first for this afternoon was generated by a great fetch of gale to severe-gale W/NW winds and will slow the easing trend into tomorrow morning.

Following this a secondary for tomorrow afternoon, was generated right behind the W/NW fetch and should maintain large sets before easing Friday.

The South West is likely to come in around the 8ft+ range most of tomorrow, possibly dipping out during the middle of the day, easing from 6ft+ on Friday with Mandurah easing back to 3ft tomorrow, 2ft+ across Perth.

Winds will be great all day and fresh E/NE-E, easing into the afternoon with stronger E/NE tending slightly more NE winds on Friday.

Into the weekend, the swell will continue to ease and stronger NE tending N/NE winds will create poor conditions Saturday so surf yourself silly before then.

We’re then looking at a poor run of winds and large westerly swells from Sunday through all of next week (possible windows in Perth/Mandurah early week) as the strong, significant high that’s currently sitting south of the country, keeping storms at arms length starts moving east.

This will see mid-latitude frontal activity pushing up high into the Indian Ocean and then down towards us next week, bringing persistent winds from the western quadrant. We’ll have a closer look at this on Friday and in the meantime make the most of the current swells.
