In fact, it becomes reinforced by a new high and this peanut high straddling Tasmania will set up a right of S’ly winds which will tend E’ly later in the week as high pressure moves to the E of the Island. Some polar low activity will supply some small S groundswell pulses this week.

A storm force polar low is better aimed at Pacific targets but we’ll still see some long period S groundswell from it this weekend, with the proviso that S’ly winds will remain persistent.

By Tues we’ll see a powerful front sweep past the state with a zonal fetch. We’ll see some small S swell wrap to 2-3ft at S facing beaches Tues.

Stronger S swell on offer for Thurs as a trailing fetch slingshots into the Tasman on an already active sea state.
