This weekend and next week (May 31 – Jun 1)

Our dynamic and exciting weekend of surf is still on track, but we're now looking at more size and a later peak into early next week.

Looking at tomorrow though, and a relatively weak but strengthening trough pushing up past us should kick up an increase in S'ly windswell through the late afternoon, but I reckon we'll be lucky to see sets reaching a very weak 3ft by dark and with gusty S'ly winds.

The swell will fade quickly overnight leaving 2ft sets max across south facing beaches, easing through the day with a W'ly tending onshore wind.

Of greater importance is the formation of a deep Tasman Low in the central Tasman Sea.

The structure of this low will see an infeed of strong to gale-force E/NE winds on its eastern flank aimed through our eastern swell window from tomorrow evening through until Sunday morning, producing moderate levels of E/NE swell.

This swell will show Sunday, but ahead of this on Saturday a SE pulse is due from a fetch of S/SE winds on the southern flank of the low tomorrow evening and Friday.

We should see building surf to 3-4ft out of the SE on Saturday, with a W'ly tending variable wind.

Come Sunday as the E/NE swell builds, open beaches should reach 4-5ft+ through the afternoon, with a peak Monday to 4-6ft, easing back slowly from Tuesday.

Winds look favourable and offshore each morning (though quickly tending S/SW Monday) with onshore breezes in the afternoons.

We'll have a closer look at this on Friday though.
