    Short-Term Analysis (through Thursday, 29 October)

    A solid round of south swell fills in across the region throughout Tuesday and eases Wednesday, favouring the more exposed northern NSW coast beaches for size and power on both days, while offering up notably smaller, fun-sized options north of Byron Bay.

    Wednesday: A still good-sized SSE swell gradually settles throughout the day, with solid head-high plus sets across northern NSW coasts, wrapping in at more like waist to chest high north of the border. Ealry light WSW/SW/SSW winds in the morning, turn SE to NE/NNE and picking up to 10-15 knots in the arvo.

    Thursday: Trailing SSE swell continues to ease throughout the day, as early light westerly land-breezes opening up fun, clean surf: up around waist to chest high across southern Queensland coasts, grading to more like chest to head-high south of the border and a tad bigger at the magnets. turning NNE during the afternoon.

    In Detail: A minor uptick in short-period easterly swell keeps wave-heights hovering around the 1-2ft mark across southern Queensland’s exposed beaches over the next few days. That originates from a distant burst of tradewinds extending east of New Caledonia last week – and by and large this offers up marginal surf potential for the region in the near-term.

    However, over the same time we’re anticipating the arrival of a mid-period south to SSE swell: linked to a slow moving low-pressure trough and an embedded low currently located roughly east of Newcastle. The system is supporting a broad, 25 to 35 knot SSE to SE fetch across the south-western Tasman Sea, supported by a broad ridge extending from a strong 1036hPa high near Tasmania.

    As the low moved below Tasmania on Tuesday the low is widely projected to remain slow moving, about 140 nautical miles off Sydney and the South Coast: maintaining a still broad ESE fetch, with the upper boundary located either side of the 35S parallel. That sees the bulk of a large ESE groundswell contained within the southern NSW coast predominantly from Wollongong south on Wednesday.

    For northern NSW and southern Queensland, this source still offers a smaller SSE wave-train spreading northward maintaining fun-sized surf both north and south of the border on Wednesday, before fading to lower levels by Thursday.
