The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Waiehu beach park.
Right off the bat, I gotta be straight with you – this 16-day window is a tough one. For the first four days, from Friday the 4th right through to Monday the 7th, the surf is on the messy side. We’ve got a solid pulse of swell running, with heights between 4ft and 7ft, mostly from the E and ENE, and the combined energy is moderate to strong (715 to 2610). But the problem is that wind. It’s blowing cross-on from the ENE, 15 to 25 km/h, and it’s just chopping everything up. The morning of Friday the 4th is "clear" but that wind is still 25 km/h, so the surface is gonna be a mess. Not worth paddling out for.
The first real glimmer of hope comes on Tuesday the 8th. The morning session is the standout of the whole forecast. The wind swings around to a light SSE breeze at 10 km/h, giving us a clean, cross-offshore flow. The swell is still a decent 6ft from the ENE with an 11-second period – that’s proper groundswell energy (811 combined energy). For a beginner-friendly reef and point break like this, the offshore wind and longer period will make for some beautiful, lined-up waves. The water temp is sitting at 80°, which is dead average for this time of year, so no surprises there. Tuesday afternoon is still okay, but the wind goes light cross-shore, so it’s not as clean.
After that, unfortunately, it’s a long, bleak stretch. From Wednesday the 9th all the way to Saturday the 19th, every single session is marked as "poor surf conditions" or "marginal." The swell drops right off, dipping to 3ft on the 9th, and though it builds back up to around 5ft to 6ft again, the wind is relentless from the ENE, mostly cross-on at 15 to 25 km/h. The period is short, often only 8 seconds, so you’re getting weak, choppy, wind-affected slop. The combined energy is low, struggling to break 500 most days. There’s just no quality on offer.
So, to wrap it up: the only true standout is Tuesday morning, September 8th at Waiehu beach park. That’s your window. Get it while it’s clean. The rest of the 16 days? A long, dusty gap of poor conditions. You’d be better off doing something else until the pattern shifts.
Rusty.
