Eastern Tasmania Forecast by Craig Brokensha (issued Monday 28th December)

Best Days: Protected northern corners for small peelers Thursday and Friday

Recap

Large NE swell to 4-6ft across the coast Saturday morning with early N'ly breeze before a gusty S'ly change pushes up from the south, turning southern corners on.

Sunday morning was much smaller but super fun with clean 3ft sets across the coast, easing back to 1-2ft this morning but crisp and clean.

This week and weekend (Dec 29 – Jan 3)

The next couple of days are looking slow with fading leftover amounts of swell tomorrow with morning offshores, then increasing N'ly winds Wednesday.

From Wednesday evening, a strengthening fetch of N/NE winds are due to develop off our coast, kicking up a building N/NE windswell to 2ft+ or so Thursday with N/NW winds.

Similar size sets are due into Friday with similar N/NW winds, possibly tending more W/NW later in the day.

A S'ly change overnight Friday will result in a drop in NE windswell from 1-2ft Saturday morning and building S/SE windswell through Saturday to a junky 3ft or so across south facing beaches along with S/SE winds.

This onshore change will be related to a surface trough pushing up the coast, with winds swinging more E/SE through Sunday while weakening resulting in a drop in SE tending E/SE swell Sunday and Monday with onshore winds.

Into early next week we've got plenty of swell on the cards, firstly arriving from the NE in the form of a mid-period trade-swell.

This swell will be generated as an active monsoon trough in the Coral Sea results in the formation of a broad low pressure gyre across the South West Pacific Ocean. Within this gyre a series of embedded lows will track clock-wise generating a pro-longed E'ly swell event for the East Coast, with NE swell spreading down radially into us at a smaller size.

The first of what could be a few pulses of NE swell is due Sunday, building to an inconsistent 2ft across open beaches ahead of a better pulse Monday to the inconsistent 3ft+ range. We're likely to see the swell ease into Tuesday and Wednesday as new levels of N/NE windswell build across the region.

This looks to be generally with onshore winds, but we'll have a closer look at this on Wednesday.
