Recap

We’ve seen large levels of E’ly swell the past couple of days, easing from Monday and more organised in southern corners yesterday. Today winds are lighter and conditions have been cleaner across a wider range of locations.

This week and next (Jun 12 - 20)

The board Tasman Low that’s been sitting directly east of us, directing a great swell generating fetch of E/SE winds through our swell window, provided one final burst of strong to gale-force SE winds last night.

This should be producing a stronger E/SE swell for this afternoon (Maria Island has upticked in period), with it due to slowly ease into tomorrow.

Open beaches are still expected to be an easy 5ft, if not for the rare bigger one, easing slowly through the day.

The low is moving slowly east but still generating a good fetch of strong SE winds off the southern tip of New Zealand’s South Island, turning more north and away from us tomorrow.

With this we can expect fun levels of E/SE swell to persist Friday to 4ft or so, easing through the day then down from 2ft or so Saturday.

Local winds over the coming days look great with a W/SW tending variable breeze tomorrow, then W/SW tending weak N/NE into Friday afternoon.

As the swell fades Saturday, increasing W/NW tending N/NW winds are due, similar Sunday.

This northerly flow may kick up some weak N/NE windswell through Monday to 2-3ft across the north magnets but with poor N’ly winds, fading Tuesday as winds shift more NW.

Longer term the outlook is much slower so make the most of the current easterly swell.
