We still have a large (1032hPa) high slow moving over NSW directing light N’lies over Tasmania. A slow moving frontal progression is gradually working it’s way clear of New Zealand longitudes while sending pulses of S’ly groundswell our way. High pressure does clear the coast this week with an increasing N’ly flow before a zonal pattern brings a W-NW flow for the weekend.

We still have a large (1032hPa) high slow moving over NSW directing light N’lies over temperate NSW and SE winds in the sub-tropics. A slow moving frontal progression is gradually working it’s way clear of New Zealand longitudes while sending pulses of S’ly groundswell our way.

The swell charts look active for the weekend but I fear the dominant westerly swell direction will have an ongoing negative impact across the South Arm.

Good news we’re then expecting a solid rebuild in wave heights as the high sets up a strong SE trade flow through the Eastern Coral Sea, with gradients squeezed by a southwards moving broad tropical depression.
