Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s shaping up at Rivermouth over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows where it’s gonna crank.

We kick off Tuesday the 25th with a bit of a flat start. The morning has a 4ft south swell with a very long 17-second period, but the 9 mph cross-shore wind is putting a bit of chop on it, and the conditions are marginal. The combined swell energy is moderate (1120), but honestly, the window looks questionable. By Tuesday afternoon the swell bumps up but the quality drops.

Wednesday the 26th is where things get interesting. That morning session is the real standout in the near term. We’ve got a building 7ft swell from the south, still with that long 17-second period, and it’s glassy – a light 3 mph southeast breeze, clean as a whistle. The energy is getting strong at 2864. This is clean, powerful groundswell with the period and direction lining up well for the break. This is a morning for experienced surfers only – 7ft is pushing it for the average punter. That afternoon the wind swings east and gets up, chopping it all out – forget about it.

Thursday the 27th is a write-off with a fresh 22 mph northeasterly putting a nasty lump on things.

Friday morning the 28th is the other little gem for the week. We get a drop in wind to a light 6 mph from the north, cleaning up a 6ft easterly swell with a moderate 10-second period. The energy is still moderate (1081), but it’s clean. This is a solid, surfable morning for a wider range of skill levels.

Saturday the 29th sees a clean but smaller 6ft east swell early, but the energy is fading. By the afternoon, the swell drops right out to 2ft. The rest of the month runs into a bit of a lull.

We then hit a proper gap through the 30th and 31st of August and into the first of September. The swell sticks around 5ft to 8ft but the crosswinds just kill it, with the energy fluctuating. Nothing worth paddling out for.

Come Wednesday morning, September 2nd, we get a small 4ft east swell with a light north-northeasterly, giving clean conditions again. It’s not big, but it’s ridable. Then Thursday the 3rd gets blown out by a strong westerly.

Here’s the long-range standout for the experts: Friday, September 4th. The model is throwing up a massive 13ft southerly groundswell with a long 11-second period, and the wind is cross-offshore and clean from the west-southwest. The combined energy is off the charts at 6098. BUT – and this is a big but – it’s predicted to be way too big for this break. This is a warning for experienced folks only, and even then, it could be unsurfable. Saturday the 5th repeats the pattern with 10ft and clean wind, also too big.

After that, things settle back down. Sunday and Monday the 6th and 7th of September show signs of life. Monday morning the 7th looks promising: a clean 6ft south-southwest swell with a very long 16-second period, light 9 mph north-northwest wind, and strong energy (2053). That’s a solid option for the experienced crew again, clean and powerful. Tuesday the 8th has some 4ft south swell with offshore wind – a nice clean option for a smaller day.

Keep your eyes on Wednesday morning the 26th and Monday the 7th. Those are your best shouts. The big stuff on the 4th and 5th is for the kamikaze crew only.

Stay safe out there.
