We’ve got a strong, expansive front passing through the Tasman at present will which supply pulses of S swell over the coming days. High pressure over NSW is moving NE into the Tasman, with a N’ly flow developing. That N'ly flow will really intensify next week with some juicy NE windswell resulting.

The high pressure belt is behaving in typical spring fashion- tracking NE as it enters the Tasman with episodic N’lies. We’ve got a small fetch out of Cook Strait at present from a decaying low pressure system, and small, compact low about to enter the Tasman. Combined with some swell from a tradewind band feeding into a long trough we’ll see concurrent small swells from these sources.

High pressure is now close to New Zealand, with an advancing trough and cold front bringing a fresh S’ly change, expected to generate a strong SE surge up the sub-tropical coast as a new high moves into the Bight and strengthens. Once the high moves into the Tasman over the weekend it’ll set up a blocking pattern but we’re expecting a few small S pulses leading up to that although winds look fickle. E'ly swell from persistent tradewind fetches should continue as a fun background source of swell.

A trough hovering about the South Coast will see a N’ly flow through Sat, with good odds for a morning NW breeze and a late tilt back to the NW, especially south of Sydney. Further north freshening N’lies look more likely. A few leftover S swell trains should hold some 2 occ 3ft sets at S facing beaches but energy will be in the way down.
