Recap

The small S/SE swell seen through the week was replaced by tiny levels of N/NE swell this morning, clean but with nothing too substantial size size.

This weekend and next week (Apr 12 - 18)

The coming weekend isn't that eventful with today’s tiny N/NE windswell due to fade tomorrow, replaced by a similar, tiny N/NE wave into Sunday morning. Don’t expect anything over 1.5ft.

Into Monday, a trough sliding up past us will bring a weak increase in SE windswell but as it is filled out by high pressure in the Tasman Sea Monday evening and into Tuesday, a healthy fetch of E/SE winds will be aimed through our eastern swell window.

A fun spike of mid-period E'ly swell is likely to build from this source into Tuesday afternoon, peaking Wednesday morning to 3ft+ or so.

Local winds unfortunately look fresh from the E/NE on Tuesday as it builds, shifting more N/NW on Wednesday morning at the peak ahead of N/NE sea breezes.

Easing levels of swell are then due into Thursday under N/NW winds.

It's worth noting that there'll likely be a flukey S'ly groundswell in the water Tuesday afternoon and Wednesday morning from a strong polar low passing under the country Sunday. It doesn't look to top 2ft though.

The next pulse of energy looks to arrive out of the E/SE, with a tropical depression forming in an established trade flow north of New Zealand possibly shifting down across New Zealand. This could generate a fetch of SE gales later next week, generating an E/SE groundswell for Sunday/Monday but we’ll look at this closer on Monday as the models diverge a little. Have a great weekend!
