Eastern Tasmania Forecast by Craig Brokensha (issued Monday 1st December)

Best Days: Tuesday morning, early Wednesday in southern corners

Recap

Saturday was good across northern corners with a mix of S'ly and S/SE swells under morning offshores.

Into Sunday a freshening onshore breeze was seen along with new levels of building E/NE swells as a surface trough sitting to our north-east started to deepen.

This trough strengthened further overnight and kicked up larger levels of swell today to 3-4ft but with a light onshore wind. A further increase in size should have been seen this afternoon with the fetch reaching maturity this morning and with winds remaining light there would have been a few options about.

This week and weekend (Dec 1 - 7)

Tomorrow morning is the pick of the period as the E/NE swell starts to ease and winds swing offshore from the W/NW.

This will be a result of the trough responsible for today's swell drifting south-east and away from our swell window resulting in a drop in size and improvement in conditions.

Open beaches should ease from a good fun 3ft, with Wednesday seeing waves continue at 2-3ft as fetch of NE winds persist in our north-east swell window through tomorrow. Winds on Wednesday will be a little less favourable as a weak S/SE change moves up the coast and freshens, so get in early across southern corners for the best waves!

Unfortunately from Thursday onwards conditions will be poor with a persistent onshore wind developing from the SE. This will be related to the S/SE change on Wednesday being attached to another deepening surface trough, with it due to stall to our south-east through the end of the week and weekend.

Initially no major size is due off the trough with winds being relatively weak but into the weekend a better fetch of strong SE tending E/SE winds will be aimed into us kicking up 3ft+ or so of windswell.

It probably won't be until Monday that winds back off and swing offshore from the W/NW but the SE swell will be easing from 2-3ft or so. More on this Wednesday though.
