High pressure support for the tropical systems which is currently anchoring a tradewind fetch in the Coral Sea weakens substantially over the short term, with E swell potential thus weakening. We’ll still see some fun E’ly trade swell in the sub-tropics, trickling down into temperate regions.

Weak high pressure moves into the Tasman with the remnants of a trough holding a modest fetch of SE breezes in the central Tasman.

The tropics is in an active state with multiple low centres expected along the monsoon trough as it responds to a phase of the MJO passing into Australian longitudes. Still plenty of uncertainty there, with any meaningful swell a while away.

Longer term is starting to look more dynamic as the tropics finally starts to fire up. Multiple low pressure systems are suggested on long range model guidance, potentially tropical cyclones.

Today’s strengthening southerly winds are related to a developing Tasman Low that is poorly aligned within our swell window, and tracking unfavourably to the east.

As suggested in Wednesday’s notes, I’m not keen on the alignment of this Tasman Low.

A final low pressure system associated with our recent complex synoptic pattern moved from a position north of New Zealand last week, into the Tasman Sea over the weekend.

The Tasman Sea currently has a number of low pressure centers, driving strong winds from a couple of directions across various parts of the basin.

A few changes to the outlook for the weekend, but in general I’m still anticipating better surf early next week.

Main features on the synoptics this week are an approaching front from the west, a strong high just west of New Zealand and a deepening surface trough in the northern Tasman Sea - the latter of which will feed additional moisture into an already-evolving dynamic setup.
