Dawn on Tuesday morning may possibly see a ‘low point’ in size between swells, but by mid morning we should see the leading edge of this new E’ly swell that is expected to reach a peak late in the day or overnight.

Over the weekend, a deepening surface trough south of Fiji is expected to form a nice easterly dip. This system looks like it’ll generate a nice flush of E’ly swell before it tracks into the swell shadow of New Zealand’s North Island (before re-intensifying and producing a large E’ly swell for the NZ East Coast mid-late next week).
This freshening trade flow will generate a building short range E/SE swell for the SE Qld and Far Northern NSW coasts.
With this swell now the single source of energy in the water, it’d be quite possible to rock up and watch the surf for fifteen minutes and not see a single wave. So bear this in mind when choosing a populated lineup, as there won’t be many waves to go around.
I am also expecting a new E’ly swell to build through Saturday - a very distant, infrequent E’ly pulse from a broad, complex system way out in the South Pacific earlier this week.
It was interesting to see the ASCAT and Windsat passes from TC Cook once it crossed New Caledonia on Tuesday - the recorded winds from the satellites didn’t match what the models had been suggesting, so confidence dropped for the E/NE cyclone swell. However, it still came in as per Monday’s expectations.
While all of this is going on, Tropical Cyclone Cook will have crossed New Caledonia, reentered the lower Coral Sea under a SW track but then recurved to the SE, towards New Zealand. This cyclone looks really impressive with surface winds upwards of 85kts, however there are several limiting factors that will impact surf size for us.
We’re still looking at a couple of tropical cyclones in the South Pacific over the forecast period.
A rebuilding trough of low pressure over the Coral Sea will freshen trade winds in our mid range swell window and thus kick up a fun E’ly swell for SE Qld this weekend.
A strong ridge extends across the Central/Northern Tasman Sea, aimed up into the Coral Sea. This fetch is stationary, aimed nicely into the Coral Sea and will continue to pump out similar sized surf over the coming days.
