There's still nothing due into the end of the week with tiny to flat conditions prevailing, but come the weekend, we've still got our large stormy S'ly swell on the cards.

A deepening and slow moving mid-latitude low will meander in from the west over the weekend, with a fetch of strong to gale-force S'ly winds Saturday, projecting into the South Arm on Sunday while weakening as the low continues slowly east.

No size is really due on Saturday at this point as the fetch lingers just out of our swell window, but into Sunday we'll see a rapid jump in size, with building surf to 4-5t+ during the day but with poor and strong S/SE winds.

With the low weakening Sunday we'll see the swell dropping fairly quickly through Monday likely from 3ft+ but with gusty and easing S/SW winds.

Longer term there's nothing too major on the cards again so maybe try and plan around Sunday, though the winds aren't ideal.

Hi Craig. In regard to the Long Wave Trough (I believe it is called) you sometimes refer to. Is it possible to have multiple LWT's at one time as there seems to be a lot of storm activity in the Southern Hemisphere at the moment.

Yeah there usually between three and six nodes around the Southern Hemisphere. The more modes there are, the more ‘mobile’ the weather patterns (ie more zonal, and a little faster). Less nodes means a slower pattern, typical of a block somewhere.
