The Lowdown
Alright, Rusty here. Let’s cut straight to the chase for this stretch of coast.
Right now, we’re in a bit of a lull – nothing worth paddling out for on the 4th or 5th. That’s a tough couple of days with a big, messy southerly swell and howling crosswinds, making for some real slop. The water temp is sitting at 57°F, which is pretty normal for this time of year, so nothing out of the ordinary there.
The first real crack at something decent comes on Friday morning (7th August). Wainui Bay Chalet will start to clean up nicely. We’ve got a 4ft swell from the SE, but the real winner is the offshore NW wind at just 6 mph, treating it properly. That light breeze and clean face are going to make for some fun, tidy waves. It’s an exposed spot so it’s grabbing everything, and with a period around 10 seconds, it will have a bit of push. This is the standout of the first week – a proper window of clean surf.
The weekend holds up too. Saturday morning (8th August) is a repeat of the same magic: 4ft of SE swell and light offshore NW winds. Clean as a whistle. It’s not huge, but it’s workable and you’ll have some space if you’re early. Sunday (9th) gets a bit smaller dropping to 3ft - 3ft, but still offshore winds so it’ll be fun for a longboard or a fish.
Monday the 10th and Tuesday the 11th turn a bit average again with onshores and shorter period slop, so the window closes pretty quick. After that, we see another clean spell from Wednesday (12th) through to Thursday (13th) with waist high, clean surf on offer thanks to light offshores. Consistent but nothing to write home about.
Now, roll into the second week and things get serious. By Saturday the 15th, the swell pumps up. The morning is a solid 7ft from the ESE under a light NW offshore. This is pushing the limits for intermediates, but for an experienced surfer in the know, this has some grunt. The combined swell energy is sitting at 887 (moderate), and that swell direction is dead on for the optimal S to SSE direction for this spot, so it’s wrapping in nicely. The wind is clean. This could be the session of the outlook period.
Sunday the 16th through Monday the 17th gets even bigger – we’re talking 10ft to 12ft of ESE swell. That’s expert level only, folks. The energy numbers are up in the thousands – 4178 on Sunday afternoon (strong), which means a lot of moving water. The wind is still offshore, but that’s serious, raw power. If you’re not comfortable in overhead surf, stay on the beach for this one.
Tuesday the 18th keeps the size at 8ft to 10ft with a clean NW offshore. Still big, still for the experienced crew, but the period drops to 10 seconds so it’s not as drawn out as a long-period groundswell.
By Wednesday the 19th, it’s starting to drop back to a more manageable 6ft - 7ft, but the wind builds to a fresh 16 - 19 mph, which puts a chop over the top. The window of true quality is definitely the 15th morning through the 16th morning. Mark that in your calendar, but as always, that’s a long-range call, so keep your ear to the ground.
Rusty.
