Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Right off the bat, we’ve got a pulse of energy rolling in. The standout period is definitely the first few days, starting Wednesday the 5th of August. A solid 7ft groundswell from the SSE, with a long 15 second period, is pushing in. The combined energy is strong at 2348. Water temp is 84°, which is a touch warmer than normal for this time of year, so that’s a nice surprise. The wind is offshore from the NE at 15 mph, so the Kugenuma Rivermouth is gonna be clean and lined up. This is serious surf for experienced surfers only – that size and power will be too much for beginners. The river mouth setup should handle that long period well, keeping the waves from just closing out. Crowds are a possibility here, as they often are.

Thursday the 6th holds in with a 6ft SSE swell, period still a solid 13 seconds, and a moderate 1105 wave energy. It’s a bit smaller, but the wind is a cross-offshore breeze from the ENE at 9 mph, keeping it clean. Still a good session for the experienced crew.

After that, things start to fade. Friday the 7th and Saturday the 8th see the swell dropping, with onshore winds creeping in, making the surf messy and marginal. By Sunday the 9th, we’re down to waist-high waves at 3ft, and the energy is weak at 346. It’s clean, but nothing to get excited about.

Then we hit a long, dry spell. From Monday the 10th all the way through Monday the 17th, there’s just no real surf to speak of. Swell sizes are tiny, under 3ft, with weak energy readings dropping into the double digits. Winds are strong offshore, which keeps the water smooth, but there’s nothing to push you in. This is a real gap in the action.

Tuesday the 18th of August might see a flicker of life, with a 4ft SSE swell and a very long 17 second period, giving a 1244 energy reading. But the wind is a strong cross-offshore breeze at 22 mph, and the forecast is murky, so it’s a gamble.

The last couple of days, Wednesday the 19th and Thursday the 20th, show a return of 7ft+ swell from the SSE, but with onshore and cross-onshore winds. The energy is back up in the strong range (1688 and 1731), but the wind is gonna chop it up and make it a battle. Not the clean gem we had at the start.

So, the call is clear: Wednesday the 5th of August is the best on offer. Hit the Kugenuma Rivermouth early. It’s big, it’s clean, and it’s got that special groundswell energy. Don’t sleep on it.

Rusty.
