The strong reinforcing cold front is now almost across the Tasman with a large (1031hPa) high moving across from the Bight and already setting up a ridge along the QLD Coast. High pressure moves into the Tasman as we end the week with a dominant role into next week before a front and possible low brings another strong S’ly surge with an accompanying S swell.

However, there's usually something brewing on the upwards flank of any block, and in this case we have a significant cut-off low forecast to move through the Bight on Wednesday and Thursday.

Next week looks like some better windows with plenty of surf expected as a high riding system tracks NE of Heard Island Sat/Sun generating a wide swathe of seas in excess of 20ft, reaching seas in excess of 30ft as it passes under WA. 

A 996 hPa low just off the coast and a 1034 hPa high in the Bight is creating a very tight pressure gradient with subsequent severe gales and an L-XL S swell event for NSW, with smaller but still significant  S swell expected for Tasmania.
