A secondary front pushing into the Tasman coalesces with a deepening low near New Zealand and the system then retrogrades back into the Tasman over an already active sea state delivering powerful S/SE swell before taking up residency in the Central Tasman for a few days next week with a slow, slow easing in big swells expected.

Easing surf ahead of the next episode early-mid next week.

Into the weekend and the low retrogrades back towards Tasmania over the weekend with plenty of size expected from the S/SE-SE.

Following that a secondary front coalesces with the primary front to form a complex Tasman which is expected to occupy the Tasman for a meaningful period of time, even retrograding back towards the East Coast over the weekend. The result will be multiple swell pulses from the S to S/SE (some very significant) right through until mid next week.
