The transitional spring pattern sees pretty decent waves wherever you look this weekend. Across the NSW coast there’s no shortage of south swell on tap over the coming days; starting out with a small, long-range S pulse on Saturday and ending with a steep rising SSE windswell on Sunday. This also sets the trend for northern NSW and southern Queensland coasts as a first, easing SSE swell overlaps with a second on Sunday.

Further south, Victoria’s Surf Coast is looking good to great on Saturday as favourable north-westerly winds coincide with a robust pulse of SW groundswell – but the party will be well and truly over by Sunday morning as the arrival of a strong onshore SSW airflow spoils conditions state-wide. A similarly unfavourable SSE airflow is also set to take the shine off conditions across South Australia on Sunday – but like Vicco both Friday and Saturday are looking the goods. Last but not least, the West Coast looks mighty fine this weekend a predominant easterly wind regime greets a combo of mid to large WSW and SSW groundswell. Wherever you find yourself, have a good one!

Sydney, Newcastle and the South Coast.
The chopping and changing spring swell-regime continues to dish up a variety of predominantly small waves across the region this weekend. Friday sees the tail end of our most recent southerly pulse rapidly fading throughout the day; probably culminating in very small 1 to 2ft waves by Saturday morning. It will, however, be well worth keeping one eye on conditions. The arrival of small, long-range/ high period S groundswell holds good potential for some clean, albeit infrequent 2 to 3ft sets across the most south facing areas – and with WNW to NE winds in force this could prove to be pretty good fun. Sunday then marks a return to strengthening onshore winds driving a steep rise in southerly windswell throughout the day – and while not so easy on the eye this could also prove worthy of a surf or two as it builds into the afternoon.

Friday
Leftover S swell slowly eases under light wind conditions. Ranging from 1 to 3ft at south facing beaches early, grading to 1 to 2ft or so elsewhere and fading later. WIND: Early light WSW tending lighter WNW, then NE at around 5 to 15 knots later.

Saturday
Tiny left overs in mixed S swell, SE swell prior to a minor rise in distant south groundswell later. Ranging from 1 to 2ft south facing breaks, rising to a slow 2 to 3ft during the morning. Otherwise small to tiny elsewhere. WIND: Early light WNW to NW, tending NE 15 to 20 knots during the afternoon.

Sunday
Small, inconsistent S groundswell superseded by rising S windswell under a freshening southerly change. Around 2ft south facing beaches early, rising to a windblown 2 to 3ft+ during the afternoon and potentially 3 to 4ft later. Grading smaller elsewhere with size depending on exposure. WIND: Early WSW to SSW quickly turning S 15 to 25 knots, then SSE later.

Queensland and Far Northern NSW
A whole lot of SSE windswell mixed with some underlying, long-range S groundswell continues to offer up marginal conditions across the region this weekend. While northern NSW coasts receive the vast bulk of this energy, the region also wears the brunt of still fresh SSE winds on Friday, before conditions start to improve as they tend lighter southeast on Saturday. It won’t be until Sunday that we see lighter offshore winds greeting a smaller, but much better organised combo of S groundswell and slight SE swell; making for a great morning to target an exposed beach.


Friday
New SSE windswell shows across the coast under fresh south, SSE winds. Ranging from a windblown 3 to 4ft at exposed northern NSW beaches. Grading semi clean at 2 to 3ft along exposed southern Qld coasts and down to 1 to 2ft at best inside the points and bays. WIND: Early inshore SSW turning SSE 20 to 25 knots, then easing to 15 to 20 knots later in the afternoon.


Saturday
SSE swell slowly eases under moderate SSE winds. Up to 2 to 3ft+ across northern NSW south facing coasts. Grading 1 to 2ft+ exposed QLD breaks, smaller elsewhere and easing later. WIND: Early lighter WSW to SSW inshore, tending SE at 10 to 15 knots, then ESE later.


Sunday
Faded SSE windswell underpinned by an inconsistent S groundswell. Ranging from 1 to 3ft at exposed northern NSW beaches, grading 1 to 2ft across exposed southern QLD beaches and tiny inside the points and bays. WIND: Early light W to SW inshore tending variable, then ENE to NE 5 to 15 knots later.

Victoria
Like last weekend, the Surf Coast’s bell is ringing over the coming days as a favourable WNW wind-pattern greets a renewed building trend in SW groundswell. It will, however, be well worth making the most of Friday and more particularly Saturday’s good to great conditions, before they turn south by Sunday. The arrival of a vigorous cold front across Bass Strait on Saturday evening leads in a robust onshore SSW airflow across the region throughout Sunday, making for far less appealing – and probably far less crowded conditions state-wide.

Friday
WSW swell continues to ease ahead of a late push in new WSW groundswell. Unsettled 3 to 4ft+ along the exposed beaches early, initially easing during the day ahead of a late push towards 4 to 5ft+. Wrapping at a clean 2 to 3ft along the Surf Coast reefs. WIND: WNW 10 to 15 knots, steadily easing throughout the arvo.

Saturday
WSW groundswell peaks at a solid, wind-affected 5 to 6ft+ along exposed beaches, deteriorating later. Wrapping at a clean 3 to 4ft+ across the Surf Coast reefs. WIND: Early WNW to NW 10 to 15 knots turning W, then SW and freshening during afternoon.

Sunday
Reinforcing SW groundswell shows under onshore SSW winds. Messy 5 to 7ft exposed beaches, rising to 6 to 8ft during the afternoon. Wind-affected 3 to 6ft on the Surf Coast reefs. WIND: SSW 10 to 20 knots early, tending S 10 to 15 knots later.

Western Australia
The Southwest is looking like a good bet this weekend as favourable easterly quarter winds greet a couple of overlapping WSW and SSW groundswells. The former persists as the dominant swell-train on Friday and Saturday; generating a solid peak later Friday before steadily easing to more accessible levels throughout Saturday. The aforementioned easterly flow is, however, forecast to be fresh at times – but it’s still a whole lot more appealing than westerlies. Sunday then sees lighter land-breezes greeting a new pulse of SSW groundswell – again offering up great conditions across exposed Southwest breaks and conditions should remain pretty good as they tend light onshore in the afternoon.

Friday
New SW groundswell coupled with potential light winds. South West coast: Lumpy 4 to 6ft sets exposed breaks. Perth/ Mandurah: Around 1 to 2ft+ exposed beaches, grading smaller elsewhere. WIND: Scope for early light land-breezes inshore, tending WNW at around 10 knots. Tending light and variable during the afternoon.

Saturday
Fading WSW swell superseded by a renewed kick in SSW groundswell under freshening offshore winds. Around 3 to 5ft early, peaking at 4 to 7ft later. Perth/Mandurah: Up to 1 to 2ft rising 2ft+ sets at the magnets later. WIND: ESE at 15 to 25 knots, easing and tending ENE, possibly light and variable later.

Sunday
SSW groundswell slowly eases under offshore winds. South West: Clean 4 to 5ft+ exposed breaks early, settling to 3 to 5ft during the day and smaller later. Perth/Mandurah: Clean 1 to 2ft early, easing later. WIND: Easterly  5 to 10 knots early, tending light and variable, then WSW 5 to 15 knots later.

South Australia
There’s a great window of opportunity across South Oz over the next couple of days as lighter northerly winds coincide with a rising SSW groundswell. Friday initially sees smaller-scale SW swell lending the focus to the most exposed areas as winds go from light north to variable during the afternoon. A new SSW swell filling in on Saturday should light up a wide variety of breaks – at least until a southerly change spoils it during the afternoon. That’s set to lead in a full day of onshore conditions on Sunday, so it’s well worth milking Friday and Saturday’s conditions while they last.

Friday
Smaller left over SW groundswell under offshore NE winds. South Coast: Clean 2 to 3ft+ at Waits and Parsons. Grading 2ft at Middleton, rising later in the afternoon. Mid Coast: Clean although only around 0.5 to 1ft. WIND: NW to northerly 5 to 10 knots, tending to light sea breezes in the afternoon.

Saturday
New mid sized SSW groundswell fills in. South Coast: Around 3 to 5ft at Waits and Parsons, grading to 2 to 3ft+ at Middleton. Mid Coast: Clean 0.5ft. WIND: Early light N to NW 5 to 15 knots before a 10 to 20 knot SSW change in the arvo.

Sunday
Speculative building trend in SSW groundswell. South Coast: Clean sets ranging from 3 to 4ft+ Waits and Parsons. Grading to 2 to 3ft+ around Middleton, bigger later. Mid Coast: WSW swell around 0.5 to 1ft. WIND: SE to ESE 10 to 20 knots.
