The Lowdown

Alright folks, Rusty here. Let's get straight into it. We've got one spot on the radar for the next couple of weeks, and it's a classic.

The window starts off with a clean little pulse on Wednesday the 22nd. Wainui Beach - Stockroute will be waking up to a WNW offshore breeze, glassy as can be, with a clean 3ft SSE groundswell. The period is a solid 13 seconds, so those waves will have some real shape and energy behind them. The combined energy is moderate (299), but it's the quality that counts here. This is a nice, easy morning for an advanced surfer to get a few clean ones without the crowd getting too thick. The water temp is about average for the time of year, nothing wild.

The morning gets the nod as the best on offer in the early period. The afternoon sees the wind swing to a light cross-on, which will put a bit of a ripple on things, so get out there early.

The surf trends down through Thursday and Friday, with very small, weak conditions. Not worth paddling out for. Then Saturday comes in with a bit more size but still ordinary.

Alright, now for the real standout. Sunday the 26th of July. This is the one to circle. The morning is a dream: glassy conditions, a 4ft SSE swell, and the combined energy is a solid moderate (598). The wind is dead glass, and the period is 9 seconds, so it's a bit more of a wind swell, but with that light air, it's going to be clean and fun. The crowd might show up, so be prepared for a few out.

The next few days get big. Monday the 27th sees a massive 13ft to 18ft S swell, but the wind is screaming from the SW at 25 mph. The energy is through the roof (6158 to 13142), but this is for experts only, and honestly, the wind and size combo looks pretty gnarly. It might be more of a kite-surfing session than a paddle session. The long period (12 seconds) on the back of that big swell will make it a beast at this beach-and-reef setup.

The second week opens up with a solid pulse on the 29th. Wednesday the 29th of July morning has a clean 8ft ESE swell with a 12-second period and a light offshore wind. The combined energy is strong (1638). This is a good call for experienced surfers, but the size is pushing into the "too big for beginners" territory. The wind is good, so it should be clean.

The rest of the week drops off in quality, with a lot of onshore wind and lumpy conditions. The following weekend (first of August) is a write-off with messy, choppy surf.

However, we have one more promising window. Monday the 3rd of August morning sees a return to clean conditions, with a 3ft ESE swell and a light WNW offshore breeze. The energy is moderate (285). It's small but clean.

The real standout of the second week, though, is Wednesday the 5th of August. The morning has a clean 2ft SSE swell with a very long 17-second period, and a gentle offshore wind. The energy is moderate (322). But the afternoon is where it gets good: a 6ft SSE swell, still a very long 16-second period, and clean cross-offshore winds. The combined energy is strong (1651). This is a high-quality option for experienced surfers, and it's the best of the late period. It's far enough out that it's promising but less certain.

Thursday the 6th of August is the last call, with an 8ft SE swell and a 14-second period. It's clean, but it's big. Only for the experts.

So, to sum it up: the best of the best is Sunday the 26th of July morning for that glassy, clean, fun-sized swell. The second standout is Wednesday the 5th of August afternoon for the long-period groundswell and clean conditions.

Stay stoked, and keep an eye on the wind.
