The Lowdown

Alright folks, Rusty here. Let’s get into it.

The first real surf on offer is Friday afternoon, August 7th, at the Wainui Beach - Stockroute (beach and reef). It’s a late start – Friday morning has nothing worth paddling for. The water is sitting at 56°, which is about 2° colder than usual for this time of year – you’ll feel that chill.

Friday afternoon has a 5ft swell from the SE with a 15-second period. That’s a proper long-period groundswell, packing a massive 1537 units of energy. The wind is a light E cross-on, so it’s going to be a bit bumpy. The period is long enough to create some real shape, but the onshore breeze will stop it from being glassy. It’s only for the advanced crew – too much power for beginners.

Saturday morning, August 8th, is where it gets good. The swell drops to 4ft from the SSE, still a solid 12-second period, and the wind is offshore from the NW at 6 mph. That’s clean, lined-up waves. This is a true standout for the first week. The combined energy is still substantial at 866. Crowds are possible here, so get in early.

The rest of the first week sees the swell dropping and the winds flirting with cross-off and cross-on conditions. Sunday and Monday have smaller surf (3ft down to 2ft), but Monday afternoon goes glassy with NW wind at 0 mph. Tiny but clean.

We hit a bit of a dry patch from Wednesday afternoon, August 12th, through to Friday, August 14th. The swell is small, wind is messy, and the waves are poor. Thursday morning has some light rain and a weak 2ft E swell – not worth looking at.

Saturday morning, August 15th, brings a cleaner 4ft from the E, but it’s not a major standout. The real excitement comes again on Monday, August 17th. The morning session has 3ft from the SSE with glassy conditions – no wind at all. That’s a score for the early crew.

Then things get wild. On Tuesday, August 18th, a big pulse hits: 7ft from the SSE, 15-second period, and a massive 2255 energy reading. But the wind is a strong cross-shore, blowing at 22 mph, so it’s lumpy and messy. This is only for experts, and honestly, it’s more of a kite-surfing setup than a clean paddle day.

August 19th and 20th see the swell jump to 12ft and 15ft respectively. That’s too big for this break, and the wind is all over the place. Only the most experienced, crazy locals should even think about it.

The real standout for the whole 16-day window is Friday morning, August 21st. The swell is a solid 7ft from the SSE, 11-second period, 1008 units of energy, and the wind is offshore from the WNW at only 3 mph. That’s clean, powerful, and beautiful. It’s excellent for experienced surfers. The following Saturday morning, August 22nd, has a smaller 4ft SE swell, but it’s clean and a good finisher.

Overall, the best session is Saturday morning, August 8th, for the clean offshore conditions, and the long-range standout is Friday morning, August 21st, for the size and perfect wind. Keep your eyes on the forecast for that one.

Rusty.
