These small lows may move north, then east and finally south or may coalesce in a more classic Tasman Low or ECL variant. Either way we should see some quality E/NE swell for Tas as the fetch draws out through the Tasman.
Primary tabs
By mid week the trough of low pressure in the Tasman is expected to be moving southwards towards the NSW south coast.
Next week still looks dynamic with potential for a deep trough or low in the Tasman, although we are going to have to play it day by day due to poor model to model and run to run consistency.
A broad trade fetch on steroids is now slowly breaking down through the Coral, Tasman and South Pacific with a tropical low whizzing away to the SE.
In between, a trough and cold front are currently approaching Tasmania, expected to bring a vigorous W/SW-SW flow o/night into tomorrow, bringing a spike in short range S swell short term.
We’ll see the current dominant high (1034hPa) straddling New Zealand which is directing a broad trade fetch through the South Pacific and into the Coral Sea slowly migrate eastwards this week with an E’ly dip forming a trough of low pressure due E of SEQLD mid week.
We should see some better quality E/NE swell from a southwards moving low pressure trough which moves from the South Pacific into the Northern Tasman next week.
Remnants of a low on the weekend are also sitting near New Zealand with swell generating fetches off the South Island and emerging from Cook Strait into the eastern Tasman. Swells from the New Zealand fetches keep surf zones active into the end of the week with mostly offshore to light winds into the weekend.
We’ll see another front and trough develop tomorrow on the leading edge of the dominant high, which sees S swell short term then a strong S/SE-SE fetch develop through the lower Tasman from mid week. Plenty of swell from this source seeing fresh S’lies, easing later in the week.
Make the most of the current energy, with some localised S/SE-SE swell on the cards for mid-next week.
