Onemana Surf Forecast and Surf Report

Alright, Rusty here, and I’ve got the scoop on what’s lining up for us. It’s been a bit of a flat spell lately, and the next few days are looking pretty ordinary. The first real chance of a wave comes on Saturday afternoon, August 29th, but even then it’s a mixed bag.

We’re looking at a bit of a slow start. Friday afternoon, August 28th, is a write-off with a weak 3ft swell from the North at 5 seconds – that’s just poor surf conditions, no energy there. Saturday morning, August 29th, brings a small 4ft swell from the NNW, but the wind is a tricky cross-off at 6 mph. The combined energy is only 116 (moderate), so it’s surfable but very ordinary. The real highlight of this early period is Saturday afternoon, August 29th. The wind goes glassy, the swell bumps up to 5ft from the N, and the combined energy hits 201 (moderate). It’s going to be clean, but the swell is short period at 7 seconds, so it won’t have much push. Still, that’s the best on offer for the first few days.

After that, Sunday through to the end of the first week is a long, dry spell. From Sunday, August 30th, right through to Friday, September 5th, the swell drops below 3ft, often with strong offshore winds that make it look clean but there’s just no wave to ride. The combined energy drops into the double digits (weak) and the scores are all zeros. It’s a solid week of nothing.

Then, out of nowhere, things get a bit interesting for the experts. On Monday, September 7th, the afternoon brings a 5ft swell from the NNW, but the combined energy jumps to 232 (moderate). The real standout is Tuesday, September 8th. The morning sees a 7ft swell from the NNW with a combined energy of 543 (strong), and by the afternoon it’s pumping 10ft from the NNW with a massive 1499 (strong to very strong) combined energy. This is a big swell, definitely only for experts as it’s well over 8ft. The period is short at 8 seconds, so it’s a windswell, not a groundswell, but it’s going to be powerful. The wind is a cross-off at 15-18 mph, so it’ll be a bit bumpy but still rideable for the experienced crew. This is the one to watch if you’ve got the skills and the nerve.

After that, it fades quickly. Wednesday, September 9th, sees a small 3ft from the North with glassy conditions, but it’s short period and only 134 (moderate) energy. Then it’s back to tiny, weak surf right through to the end of the forecast on September 12th. The water temp is about 58°F, which is pretty normal for this time of year, so no surprises there.

So, to sum it up: a small, clean window on Saturday afternoon, August 29th, is the best for the average surfer. But for the big-wave hunters, Tuesday, September 8th, is the real deal – a massive, powerful swell that’s all about the expert-only session.
