Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what's coming our way for Rivermouth. Honestly, it's a bit of a mixed bag, and we’ve got to be patient. The next couple of weeks are gonna see some proper size, but the conditions are going to be a real challenge to line up.

Right now, the water is sitting at a cool 64°, which is a solid 4° colder than normal for this time of year. That’s a noticeable drop, so you’ll want the thickest rubber you’ve got.

The forecast starts off a bit flat for a few days, with nothing really worth paddling out for until we get to Wednesday, August 6th. That morning, we see a small window of opportunity. A 4ft swell from the East, with a period of 10 seconds (moderate energy of 346), but the real story is the near-glass. A light 3 mph breeze from the NNW is going to have the surface clean. It's not big, and the scores aren't off the charts, but for a quiet, small-wave session, that’s your best bet early on. The afternoon gets a bit choppy with a cross-breeze.

We then hit a lull of smaller, cross-swell energy through the end of the week. The swell direction swings to the SSW with a very long period, up to 15 seconds. That kind of groundswell is better suited for points and reefs, and at a river mouth, it can sometimes wall up or bend around. But with persistent cross-winds, it's not going to be clean. The energy values are moderate, but the quality just isn't there.

Now, looking further out, things get heavy. From August 10th onwards, we’ve got a massive pulse of swell hitting. It kicks off on Monday, August 11th with a 12ft South swell, but it's accompanied by strong onshore winds, making for lumpy, blown-out conditions. This is a full-on stormy setup, and honestly, with that much wind and chop, it might be more interesting for the kite crew than paddle surfing.

The real behemoth arrives on Wednesday, August 13th. We’re talking a massive 21ft swell from the ESE with a 12-second period. The combined wave energy is absolutely pumping at 11070, which is intense. But here’s the thing: the conditions are calling for cross-shore winds, which would be okay, but a 21ft wave at Rivermouth? That’s for experts only. This is a massive, powerful swell. The same pattern holds through to the 14th, with waves well over 8ft. While the wind forecasts look decent, the sheer size will limit it to only the most experienced crew.

After that big event, the swell slowly drops. By Saturday, August 16th, we’re down to a 7ft East swell, and the wind is light. It's still a bit big for a beginner, but it's getting back into a more manageable range for the average surfer. We get another small, clean-looking morning on Sunday, August 17th, with a 5ft E swell and glassy conditions from a light Southerly. That’s a sneaky good option if the swell has backed off enough.

Bottom line: The first week is mostly small and bumpy, with only the early morning of the 5th looking clean. The second week brings a massive swell that is too big for most of us, but if you’re an expert and can handle serious size, the period around the 12th and 13th is where the biggest energy is. The end of the second week, around the 15th and 16th, looks like the best bet for the average surfer to find some clean, manageable waves.
