Eastern Tasmania Surf Forecast by Craig Brokensha (issued Monday 29th January)

Recap

Tiny Saturday morning, and only small Sunday but later in the day we saw some N/NE windswell building, peaking through today with average winds until an offshore change has since moved through.

This week and weekend (Jan 30 – Feb 4)

With today's change we'll see the N/NE windswell ease into tomorrow from 3ft across north-east magnets, while a weak S/SE change up the coast will produce some small weak S/SE windswell to 2ft+ or so. S/SW tending S/SE winds will only favour southern corners though.

Both swells will fade into Wednesday morning, but we'll see a stronger cold front pushing up past us through the day, kicking up a stronger increase in S'ly swell to 3-4ft by dark across south magnets.

This will be with SW tending S winds, easing Thursday from 3ft+ with morning W/SW-SW breeze.

Of greater importance is the E/NE groundswell that's due to build through the end of the week.

Firstly we'll see some small inconsistent E/NE trade-swell energy from a stationary fetch of E'ly trades that have been setup between Australia and New Zealand the last couple of days, building later Wednesday but more so through Thursday to an inconsistent 2-3ft across magnets into the afternoon.

Tropical Cyclone Fehi has just been named in the Coral Sea and we'll see Fehi drift south and into the trade-flow over the coming days.

This will result in a strengthening fetch of E/NE winds being projected through our swell window, before Fehi makes and extra-tropical transition and passes across New Zealand Thursday.

The movement of Fehi will be quick which isn't ideal, but wind speeds are expected to reach the gale-force range out of the E/NE on top an active sea state.

This will generate a large pulse of E/NE groundswell that's expected to fill in overnight Thursday and peak Friday morning to 4-6ft across swell magnets, dropping quickly owing to the rapid movement of the low across New Zealand.

Conditions look great for most spots Friday morning with a SW'ly, tending SE into the afternoon.

Come Saturday we'll be looking at much smaller 2ft to occasional 3ft leftovers.

Our next swell looks to come from the south on Sunday afternoon and Monday as a polar front slides up from the south, but more on this Wednesday.
