Best Days: Mid Coast tomorrow morning, South Coast keen surfers Saturday morning

Recap

Building surf with strengthening onshore winds across the Mid Coast through the day yesterday, more stormy into the afternoon and today with 3ft+. The South Coast dropped a little into yesterday morning back to 3-4ft off Middleton with clean conditions, bumpier into the afternoon as the swell started to kick, very large and choppy/stormy today with the arrival of a long-period S/SW groundswell.

This week and weekend (May 30 – Jun 2)

Today's large and stormy S/SW groundswell event will start to ease through tomorrow as the slow moving frontal progression pushes slowly east, while still aiming strong to gale-force S/SW winds through our southern swell window today.

Unfortunately winds will be poor for the South Coast and fresh and gusty from the S'th as the S/SW groundswell eases from 6ft+, smaller and down from 4ft or so on Friday as S/SW winds persist.

The Mid Coast will be the pick tomorrow morning with a cross-shore S/SE breeze, tending S/SW into the afternoon and easing sets from 2ft, tiny Friday.

The weekend is looking slightly better as the swell continues to drop along with a more variable breeze on the South Coast Saturday morning. Size wise it looks like we'll be seeing easing 2ft+ sets off Middleton, tiny on the Mid Coast.

Winds will freshen from the W/NW Sunday morning ahead of a SW change linked to a low projecting up and into the south-east of the state through the day. When winds are favourable the surf looks tiny, with onshore building S/SW surf into the afternoon, peaking Monday to 3ft+ off Middleton.

Winds will remain onshore though and out of the S'th, with tiny surf on the Mid Coast, cleaner Tuesday with a morning W/NW breeze but small easing S windswell.

There's nothing too significant through the rest of the week, with a small and inconsistent long-range W/SW groundswell for the Mid Coast Wednesday, but with it being generated so far away no major size is due. We'll have another look at this on Friday though.
