The swell charts look active for the weekend but I fear the dominant westerly swell direction will have an ongoing negative impact across the South Arm.
What follows will be an extended period of onshore winds and large surf, with embedded pulses in the 8-10ft range as the storm track is elevated and the SW of the state is in the W’ly flow.
Good news we’re then expecting a solid rebuild in wave heights as the high sets up a strong SE trade flow through the Eastern Coral Sea, with gradients squeezed by a southwards moving broad tropical depression.
The high is slow moving, with a light W’ly ridge across Tasmania. We’ll see pulses of S’ly groundswell this week from the deep fetches located in the Far Southern Tasman.
The swell charts look active for the weekend but I fear the dominant westerly swell direction will have an ongoing negative impact at those coasts best suited to the accompanying NW airstream on Saturday.
A big dominant high (1032hPa) is sitting over SE Australia, with a series of powerful fronts passing well to the south and the progression slowed in New Zealand longitudes. The high is slow moving, setting up a dichotomy with N’ly winds across temperate NSW and a more SE flow in a ridge along the sub-tropics. Across all regions we’ll see pulses of S’ly groundswell this week from the deep fetches located in the Far Southern Tasman.

Flag the weekend... We've got some good waves on the way for early next week.
Into next week and very active Indian Ocean storm track spawns a slow moving massive gyre with multiple (at least 3) back to back to back severe gale fetches which will generate L to XL surf, primarily benefitting the NW and Indonesia. SW WA will be mostly in the storm track and thus subject to a mostly stormy, onshore flow, with the breaks between onshore episodes unlikely to be sufficient for surf to clean up away from a few select winter spots.
The main features for the weekend are a rapidly easing swell and a steadily abating wind that'll tend westerly on Saturday before becoming light and variable on Sunday.
