Recap
A small fun swell for Saturday morning with offshore winds, fading through the day and tiny into yesterday and today.
This week (Jan 10 - 13)
Tiny surf should continue tomorrow but into Wednesday an intense mid-latitude low passing under us will generate a fetch of severe-gale to storm-force W/SW winds through our western swell window.
The low will track very fast which isn't ideal, but the strength of the winds should still produce a kick in W/SW swell Wednesday afternoon, building rapidly to 3ft across Clifton with an early NW'ly giving into strong W/SW winds.
Offshore NW winds are due again early Thursday but the swell will recede rapidly from 2ft to maybe 3ft, smaller and 1-2ft Friday morning.
This weekend onwards (Jan 14 onwards)
We've got a significant cold outbreak forecast to occur west of us on Friday with a fetch of gale to severe-gale W/SW winds initially being too far north.
As the system moves east though, a tight fetch of severe-gales will be generated right under us Saturday afternoon, tending SW into the evening.
This should produce a solid increase in W/SW swell later Saturday, reaching 3ft by late and then easing slowly from 3-4ft Sunday morning.
Winds unfortunately look to be onshore through this swell event, including Sunday morning, but we'll confirm this Wednesday.
