Eastern Tasmania Forecast by Craig Brokensha (issued Friday 28th November)

Best Days: Saturday morning south swell magnets

Recap

The surf started to build through yesterday but with poor winds, while today a good mix of S'ly and S/SE swells came in at 2-3ft across spots exposed to the south with larger sets at swell magnets under morning offshores.

This weekend and next week (Nov 29 – Dec 5)

Our mix of S'ly and S/SE swells should persist through tomorrow to 2ft+ across south swell magnets under offshore W/NW tending SE winds.

Unfortunately a new strong pulse of S'ly groundswell due on Sunday looks to be now spoilt with strengthening onshore winds and poor weather. This swell produced by strong polar low is expected to come in at 3ft+ across south facing beaches, but a deepening surface trough right off us will deliver fresh E'ly winds through the morning that will then strengthen during the day.

This onshore breeze will be linked to a broad fetch of E/NE winds being aimed towards us in the Southern Tasman Sea, with a building E/NE swell due through Monday, reaching a peak in size Tuesday morning.

Open beaches should increase to 3-4ft later Monday and then ease from 3-4ft Tuesday morning as strong onshore winds ease back and tend variable from the north as the surface trough generating the swell drifts south. This will be the day to surf.

Wednesday will be much cleaner and straighter but smaller with an easing E'ly swell from 3ft under W/NW tending N'ly winds.

Another similar but weaker trough is expected to move into the Southern Tasman Sea mid-week but only small levels of NE swell to 2ft or so are expected at this stage. More on this Monday though. Have a great weekend!
