Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the table for Kugenuma Rivermouth over the next couple of weeks. I’ll be straight with you – there’s a long, flat spell to get through before we see any real action.

We’re looking at a dry patch right off the bat. From Sunday the 9th all the way through to Friday the 21st of August, the surf is pretty much a no-go. Most of this period is a mix of tiny, weak swells with poor conditions. On Monday the 10th and Tuesday the 11th we see a few small waves, 1.6ft to 2ft, but it’s all very ordinary. The best of that early stretch might be Tuesday morning, when the wind drops to glassy with a clean 1.6ft SSW swell, but there’s hardly any energy behind it (70). It’s a quiet spell in the water. Water temperature is sitting at 81.3°F, which is pretty much normal for this time of year so don’t expect any surprises when you jump in.

That all changes on Saturday the 22nd. This is the real standout of the forecast, but it’s over a week away, so keep an eye on it. Saturday morning is looking like the best bet: a clean 2.6ft groundswell from the SSW, period jumping to a very long 13 seconds. That’s long-period energy, which will produce some proper, well-shaped lines, especially at a rivermouth setup. The combined energy is a solid 321 (moderate). The wind will be a gentle offshore from the NNE, which means clean, groomed faces. Crowds are often an issue here, so get down early.

Saturday afternoon on the 22nd sees the swell bump up to 3.9ft from the same SSW direction, with a period still at 13 seconds. The energy ramps right up to 560 (strong) but the wind goes cross-off from the ENE. It’ll be clean but the bigger swell and stronger energy might make it a bit more challenging for beginners. Sunday the 23rd morning is also promising with a 3.3ft SSW swell and a solid 12-second period, combined energy at 328 (moderate), and light cross-off winds keeping things clean.

Monday the 24th looks like it’ll get messy again with onshore winds, so the window is really that Saturday the 22nd and maybe Sunday the 23rd morning. That Saturday (22nd) morning is the one I’d be circling on the calendar – it’s the cleanest, best shaped, and most surfable of the whole run.
