The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Waiehu beach park.

Honestly, the next week and a half is a bit of a grind. We’ve got a solid stretch of poor surf conditions from now through to the end of July. The wind is stuck in a cross-on pattern from the ENE or NE, blowing at 9 to 16 mph, which is keeping the surface choppy and messy. The swell is mostly small, between 4 ft and 6 ft, with a short period of 6 to 8 seconds, so the wave energy is weak to moderate. It’s just not clean enough to get excited about. There’s a gap of about eight days here where I wouldn’t bother paddling out.

Now, look sharp for the morning of Wednesday, the 29th of July. That’s the standout. We’ve got a 13 ft swell from the east with a 14-second period, and the wind is offshore from the NNE at 9 mph. The combined swell energy is strong. That’s the real deal. It’s a big, powerful groundswell, and with the offshore wind, Waiehu beach park should have some proper, clean lines. But listen, this is a big one – 13 ft is expert territory, and this is a reef and point setup, so those long-period swells will wrap in nicely. The afternoon gets even bigger, with a 20 ft swell and a very strong energy reading, but still with that offshore wind. That is massive, and only for the brave. The morning of the 30th of July still has a strong 10 ft swell from the east with light offshore winds, but the period drops to 9 seconds, so it’s a bit less organised.

The water temperature is sitting at 79°F, which is about average for this time of year, so no surprises there.

So, to sum it up: the first week is a write-off. The real action is on the 29th of July morning and afternoon, and the 30th of July morning, with serious, clean, offshore swell for the experts. It’s a long way out, so keep an eye on it, but the potential is huge.

Rusty.
