Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get stuck into what’s cooking at Kugenuma Rivermouth over the next couple of weeks.

Right off the bat, it’s a bit of a slow burner. The first few days are flat and not worth a second look. The water’s a touch warmer than normal for this time of year, sitting around 82°F, which is nice.

We’re looking at a real quiet start. From Wednesday the 2nd right through to Saturday the 5th, the swell is tiny—only 1ft to 2ft—with a short, weak period. The combined energy is weak, barely making it into double digits (19 to 94). The wind is mostly onshore or cross-off, and the conditions are just poor. You’d be better off doing something else.

Sunday the 6th and Monday the 7th are still a write-off. You’ve got fresh offshore winds, but the swell is practically non-existent at 1ft with a period of just 7 to 8 seconds. The energy is weak (23 to 38). Not a ripple worth paddling for.

Then things get interesting. On Tuesday the 8th, the morning looks messy with a strong onshore wind and a 6ft swell, but by the afternoon, the wind swings offshore from the north and the swell jumps to a solid 10ft from the SSE. The period is a solid 12 seconds, and the combined energy is a massive 2429. That’s strong, powerful stuff. This is clean, lined-up surf, but it’s big. Over 8ft, so this is for experienced surfers only. Beginners, stay on the beach.

Wednesday the 9th keeps the run going. Offshore winds from the north, a 8ft to 8ft swell from the SSE, a period of 10 to 11 seconds, and energy levels of 1244 to 1792. That’s excellent surf for those who know what they’re doing. It’s a bit on the bigger side, but clean and offshore.

After that, it drops right off again. Thursday the 10th through to Monday the 14th is a flat spell. The swell is under 3ft, mostly in the 1ft to 1ft range, with onshore or cross-off winds and weak energy (45 to 134). There’s nothing to ride.

Now, here’s the standout. Tuesday the 15th of September. This is the one to circle on the calendar. We’ve got a 8ft to 7ft swell from the SE, with a very long period of 15 seconds. That’s groundswell, and it’s packing a punch with combined energy of 2347. The wind is offshore in the morning and light cross-off in the afternoon. This is clean, powerful, and well-shaped. Again, over 8ft, so it’s expert territory. This is the best on offer, no question.

Wednesday the 16th is still decent, with a 5ft to 4ft swell from the S and SE, period of 11 seconds, and offshore winds. The energy is moderate to strong (869 to 641), but the conditions are a bit more marginal. Still a good option.

From Thursday the 17th, it’s winding down. The swell drops to 4ft to 5ft, but the wind is onshore or cross-on, and the energy is moderate (294 to 456). Not great.

So, to sum it up: the first week is a total write-off. The real action is on Tuesday the 8th and Wednesday the 9th, and then the absolute standout is Tuesday the 15th of September. For the experienced crew, that’s your day. Crowds are likely at the river mouth, so get in early.

Rusty.
