Still a complex, troughy pattern in play with a slow moving trough of low pressure drifting south off the Gippsland coast towards waters East of Tasmania. A front sweeping in behind the trough is bringing a clearing W’ly flow through temperate NSW today, reaching the sub-tropics tomorrow.

Monday, 27 March 2023

A small trough of low pressure off the Gippsland coast is replaced by another trough system later in the week. Far to the south of this hot, soupy mess a series of stronger polar lows are traversing the Far Southern Ocean sending small long period S swell trains our way. 

Friday, 24 March 2023

Long period S swells will be the dominant swell trains next week (for NENSW) as a complex deep low traverses the far southern Tasman Sea and becomes slow moving in New Zealand longitudes.

In the Coral Sea a monsoon trough remains active with a persistent but unspectacular trade-wind flow maintaining a small fun E swell signal north from Port Macquarie. The remnants of a low near the South Island are now dissipating after a final flare up yesterday. 

Monday, 20 March 2023

Compared to Fridays notes the front/low in the Southern Tasman is a stronger system while the tradewind pattern is weaker and more disjointed. That will see S quadrant swells dominate through most of the week through temperate-sub-tropical  NSW, with a smaller tradewind swell signal north of the border being the dominant swell train.

All eyes out to the Pacific swell window this week with a typical late Summer/early Autumn pattern setting up. Low pressure centres well to the East of Fiji (near American Samoa), west of Fiji and NW of New Caledonia will all chug away on a long tradewind belt setting up presently and enhanced by a dominant high pressure cell moving SE of Tasmania early next week.

Our eastern swell window remains the focus for the coming week.

Sunday has some promise for an easterly swell to fill in, sourced from two regions.

Friday, 10 March 2023

A broad area of low pressure  drifts NE to be close to Lord Howe Island on Mon, with ESE-E winds on the southern flank of the low pressure area. That system does look to persist in the Tasman at least until the middle of next week, generating fun sized SE-E swells. It's not a tremendously tight squeeze between the low and a high drifting E of Tasmania but it will be persistent enough to generate fun surf.

The complex low pressure gyre is slowly moving under Tasmania with the majority of any swell generating winds in the swell shadow of Tasmania. Hot air being dragged down from tropical Australia is now slowly being displaced by the cooler air from the Southern Ocean and driving a synoptic W’ly flow across temperate NSW with the sub-tropics still subject to hot, Spring-like N’lies.
