Southern Tasmania Surf Forecast by Craig Brokensha (issued Friday 18th March)

Best Days: Sunday morning, Monday for beginners, Tuesday, early Wednesday

Recap

Tiny waves both yesterday and this morning with clean conditions each morning. A strong onshore change has since moved through though, creating poor conditions.

This weekend (Mar 19 - 20)

Today's onshore change is linked to two relatively weak cold fronts moving in from the west, producing two pulses of W/SW swell for tomorrow.

The first isn't looking too strong with 1-2ft sets tomorrow morning, developing to a stronger 2ft through the day, easing back from 1-2ft Sunday.

Winds tomorrow will be poor though with a strong onshore S/SW breeze, easing through the day.

Cleaner conditions are due into Sunday with a NW offshore ahead of SE sea breezes.

Next week onwards (Mar 21 onwards)

Tiny surf is due into Monday but probably not below 1-1.5ft, a good day for beginners, while Tuesday's swell is looking great still.

A vigorous polar low is forecast to develop over the weekend, generating a fetch of storm-force W/SW winds through our south-west swell window from tomorrow through until Sunday morning.

A strong long-period SW groundswell will be generated, peaking Tuesday morning to a good 3ft across Clifton before easing back through the day and down further from 1-2ft Wednesday.

Conditions look good with an early N/NW breeze due to freshen from the N/NE Tuesday, and then N/NW winds Wednesday ahead of SE sea breezes.

There's then nothing significant due until later Friday and more so Saturday, and that will be in the form of a vigorous and slow moving polar frontal progression firing up under the country. This should produce a good W/SW groundswell peaking Saturday to 3-4ft, but we'll have a closer look at this Monday. Have a great weekend!
