Todays W’ly change was the herald for a strong frontal progression which is currently unfolding at the gateway to the Tasman Sea. We have a front tied to a small low E of Tasmania with a much deeper parent low well to the south of Tasmania. There are multiple swell generating fetches associated with this complex low arrangement, favouring NENSW S swell magnets for size.

Yesterday’s W’ly change was the herald for a strong frontal progression which is currently unfolding at the gateway to the Tasman Sea. We have a front tied to a small low E of Tasmania with a much deeper parent low well to the south of Tasmania. There are multiple swell generating fetches associated with this complex low arrangement.

Cold, wintery weather and surf, peaking in size through Wednesday as the swell angle shifts more south along with an increase in period.

We’re past the peak of the current S swell event as the large low pressure system drifts towards New Zealand, weakening as it does so and a more mobile high pressure system moves north-east into the Tasman Sea, bringing N’ly winds.
