The Lowdown
Alright, grab a seat. It’s Rusty here, and honestly, Oahu’s South Shore is looking a bit flat and sad for the next couple of weeks. We’ve got a long stretch of poor conditions ahead with not much to get excited about. Let’s break it down.
The only real window of interest, if you can call it that, is a brief pulse on Tuesday the 8th of September. That afternoon, Rabbit/Manana Island (Oahu) will see a 6 ft swell pushing in from the ENE, with a period of 11 seconds. There’s moderate wave energy in the water (856), but the wind is a cross-off from the SW at 12 mph, which will keep things clean. Water temps are sitting at 80°, which is bang on average for this time of year. The guides say this spot is fairly consistent and exposed to swell, and while it’s the best of what’s on offer, the ride quality is only marginal due to questionable tide. Still, if you’re keen, Tuesday arvo is your go.
Now, I’m not gonna sugar-coat it—after that, it’s a long, bleak run. From Wednesday the 9th of September right through to Wednesday the 23rd of September, every single forecast is stamped "poor surf conditions." The swell tries to linger, but the wind just ruins it. For days on end, we’ve got cross-onshore winds, mostly from the ENE, blowing anywhere from 12 mph all the way up to 25 mph. The wave heights bounce between a knee-high 2 ft and a lumpy 6 ft, but the periods are short and choppy, and the energy never really builds into something worthwhile.
There’s a few moments where the swell touches 5 ft to 6 ft around the 16th to the 19th of September with cross-shore winds, but the period drops to 8 seconds, and the combined energy (315 to 567) is still not enough to overcome the mess. By the 22nd of September, we’re down to 2 ft and barely any energy (98). The following day brings a risk of thunderstorms and a small bump in swell, but again, the period is a weak 6 seconds.
Bottom line: if you’ve got a kite, the beach might look interesting for you when the breeze picks up and the swell is lumpy, but for paddle surfing? Don’t hold your breath. The one standout is Tuesday afternoon, 8th September. After that, it’s a 15-day stretch of flat or ugly. Not much we can do but wait for a change in the pattern.
Stay patient.
Rusty.
