A strong polar low and front is passing south of the state at the moment, and will generate a solid swell increase for Tuesday, before size eases slowly through Wednesday.
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.
A blocking pattern is setting up in our swell window, which will be the main cause of the easing trend later this week.
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.
In the South Pacific a long, persistent tradewind fetch has been chugging away with small, pulsey E swell expected this week.
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.
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. The primary focus of this swell is temperate NSW inside the Hunter curve, with other areas seeing much less swell.
The combintion of 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 XL S swell event. The primary focus of this swell is temperate NSW inside the Hunter curve, with other areas seeing much less swell.
Todays late pulse should finally fill in and supply a few 4ft sets tomorrow between the Capes with tiny 1-2ft surf in Mandurah, 1ft in Perth. Winds remain predominantly E’ly with high pressure ridging in under the state and an inland trough.
No change to the f/cast. Small background energy from the South Pacific holds fun surf next week with a small pulse on the weekend.
