A second, much stronger swell from the E/NE to NE quickly follows as a dominant high slips under the state and quickly has a pressure gradient squeeze from an inland trough and the remnants of ex TC Seth.
A long cradling fetch of E/SE Tradewinds forms in that general region, which is likely to be a more reliable swell producer, especially for the more exposed breaks on the Burnett coast.
More action in the tropics next week. Later this week another tropical low is expected to form in the South Pacific- possibly between Fiji and Vanuatu.
Not the best outlook with mostly tiny surf and tricky winds from the eastern quadrant.
Swell from ex TC Seth, which transitioned into a gale force sub-tropical low Sun is the major synoptic feature this week, responsible for both swell production and directing gradient winds as it slowly weakens and meanders close to the NENSW/SEQLD coast for the next few days.
Small swells and not favourable for Perth and Mandurah. There should be a couple of fun mornings in the South West this week.
The coming outlook remains poor with persistent winds out of the south and no major swell for the Mid Coast, just tiny teasing swells.
An average couple of days ahead before conditions improve from Thursday along with a fun mix of easing swells.
Stronger surf fills in next week as a more winter-calibre storm pattern begins to set in, with storms off Japan following a favourable jet stream pattern.
An intense sub-tropical low is expected to reach storm force Sun, spraying the entire East Coast with E/NE groundswell. Tasmania won’t miss out.
