Kugenuma Rivermouth Surf Forecast and Surf Report

Alright, this is Rusty, and I’ve got a look at what’s coming up for the Kugenuma Rivermouth stretch. Let’s be straight with you – it’s a lean start, and there’s a long wait for anything worth paddling out for.

The first real pulse of decent surf doesn’t show up until Monday the 3rd of August. Before that, from Tuesday the 28th of July right through to Sunday the 2nd of August, it’s flat or junk. The swell is tiny, period is short, and most of the time the wind is onshore or cross-onshore, making it messy. The water temp is sitting at 82°, which is a touch warmer than normal for this time of year – feels like a bath.

Monday the 3rd of August finally brings some life. The morning sees a clean 3 ft swell from the southeast with a 17-second period. That’s proper groundswell energy, and the combined energy hits 355 (moderate). The wind is light and cross-off from the ENE – clean, workable. By the afternoon, it gets even better: 3 ft from the southeast, same long 17-second period, and the wind swings to a light offshore from the NNE. The combined energy jumps to 558 (moderate to strong). This is the best on offer in the whole window. The Rivermouth should be handling that long-period swell well, with clean faces and some push.

Tuesday the 4th of August is a step up in size but a step down in ease. Morning: 5 ft southeast swell, 18-second period, strong offshore from the NNE (20 km/h). The combined energy is 1628 (strong). That’s a solid groundswell, but the size is pushing into expert territory – too big for beginners. The afternoon is 7 ft from the southeast, same long period, with a cross-off wind from the ENE. The energy is 2659 (strong). Getting bigger, and the wind is still clean, but the current and size will be challenging.

Now, Wednesday the 5th of August – this is a big water day. The morning swell is 21 ft from the ESE with an 18-second period, and the wind is a fresh 30 km/h offshore from the NNE. The combined energy is a massive 25547 (very strong). That is way too big for this break. Even the afternoon, with 18 ft from the SSE and a 14-second period, is still extreme. Only for the absolute elite, and even then, it’s questionable. This setup looks more interesting for kitesurfing than paddle surfing.

After that, it drops off quickly. From Thursday the 6th of August all the way to Wednesday the 12th of August, it’s back to small, weak, and mostly onshore wind or poor conditions. A few mornings with glassy or offshore winds, but the swell is tiny – 1.0 ft to 3 ft – and the energy is low. Not worth suiting up for.

The standout is Monday the 3rd of August afternoon. That 3 ft, 17-second groundswell with light offshore wind is the cleanest, most user-friendly window in the whole 16 days. The Rivermouth will be running nicely. Tuesday the 4th morning is solid for strong surfers, but it’s bigger and more demanding.

Rusty out.
