Eastern Tasmania Surf Forecast by Craig Brokensha (issued Monday 24th June)

Best Days: South swell magnets tomorrow morning, next week

Recap

Our secondary pulse of SE swell came in around the expected 3-5ft on Saturday with better winds than forecast, while Sunday was clean again with easing 3ft sets.

A new S'ly groundswell should have started to show today, peaking this afternoon to 4ft across south swell magnets.

This week and weekend (Jun 25 - 30)

Today's S'ly groundswell will drop back rapidly through tomorrow, so get in early for the most size. South magnets should hopefully see sets to 2-3ft, tiny into the afternoon and with a persistent NW offshore wind.

Following this there's nothing significant on the cards until late week and more so the weekend.

A strong blocking high will move slowly east as cold fronts moving in from the west progress further towards us.

This will squeeze the western flank of the high and direct a N'ly fetch through our northern swell window, not reaching any significant strength until Saturday.

The alignment isn't great but with 18 hours of strong N'ly winds we should see a kick in N/NE windswell on the coast Saturday afternoon to 2ft to maybe 3ft at north-east facing beaches though with poor N tending N/NW winds.

A W/SW change will be seen overnight but come Sunday morning the swell looks to be fading from a small 2ft max across north-east magnets.

Of greater importance are the developments on the northern flank of the high, with a deepening tropical low expected to form in an established trade-flow, directing a fetch of strong to gale-force E/NE winds through our swell window north of New Zealand this week.

We may even see the fetch swing more NE and encroach into the Tasman Sea as a low pushes off the Australian mainland and stalls in the Tasman Sea, though we'll have to review this in the next few updates.

A prolonged E/NE groundswell event is a possibility, building early next week and peaking Wednesday/Thursday to what at this stage looks to be 4-5ft+ or so. Check back here through the week for updates.
