Southern Tasmania Surf Forecast by Craig Brokensha (issued Wednesday 19th July)

Best Days: Friday morning, Monday onwards next week

Recap

Tiny waves yesterday, while today a gusty S'ly change is kicking up a building S'ly windswell along with poor conditions.

The fetch behind this change isn't as good as expected on Monday and with this we're only due to see sets peaking at 2ft and winds are only due to swing offshore on dark (not ideal).

This week and weekend (Jul 20 - 23)

With winds swinging back offshore on dark today, this will cut off the fetch of swell generating winds, and with this there's no real size due into tomorrow morning, with only weak 1-2ft leftovers,

A dawn W/NW'ly is expected to give into a fresh SW change as a polar front projecting up and towards the state, slips east. This will see winds swing S/SE into the afternoon along with a poor S'ly windswell.

Come Friday winds should swing back offshore from the NW but with a small mix of easing swells from 1-2ft.

Our small S/SW groundswell for Saturday has been downgraded a little, with the polar front generating it being a touch weaker, along with winds taking a more W'ly bias.

With this we're only expected to see 1-1.5ft waves max Saturday, if that, with offshore winds.

Of greater significance is a strong polar front forming south-west of us on the weekend, and if all goes to plan we'll see a fetch of W/SW gales projected up through our south-western swell window.

This should generate a moderate sized SW groundswell (3ft+) for Monday afternoon and Tuesday morning with favourable winds, followed by fun levels of S'ly swell as the storm stalls to our south, but more on this Friday.
