Rivermouth Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s shaping up at Rivermouth over the next couple of weeks.

Right now, it’s a slow start. The first decent surf doesn’t show up until Friday the 31st of July, with a chest-high 6ft swell coming out of the ESE, but it’s crossed up with a cross-on wind, so it’s gonna be choppy and a bit of a slog. The combined swell energy is moderate at 808, but the conditions are just marginal. That Friday afternoon and into the weekend stay pretty average—same size range, but the wind stays cross or cross-on, and the energy drops off. Not worth getting excited about.

Through the start of next week, Monday the 3rd and Tuesday the 4th see some cleaner moments. Tuesday morning is actually looking alright: the swell drops to a waist-high 4ft from the ESE, but with a light north wind turning cross-offshore, the surface cleans right up. Combined energy is only 362, so it’s weak, but for a beginner-friendly spot like Rivermouth, it’s a fun little session. The water temp is 69°, pretty normal for this time of year.

The middle of the week (Wednesday the 5th) fades into smaller 3ft stuff, and then Thursday the 6th brings a new pulse. That morning is a write-off with 19 mph southwesterlies, but Thursday afternoon throws up a solid 7ft SSW groundswell with a long 14-second period. Combined energy jumps to 1741—moderate-strong—but the wind is still cross. It’ll be lumpy, and because that period is long, Rivermouth as a river mouth might see the waves breaking a bit too straight. For experts, it could offer some grunty walls, but it’s not clean.

Friday the 7th stays messy with strong cross-shore winds. The real standout I’m eyeing is Saturday the 8th of August. The morning is already clean with a cross-off wind and a 4ft SSW swell (14-second period), but the afternoon is the gem: glassy-like conditions, light NNE cross-off breeze, same size swell, and combined energy at 648. The forecast says “very good surf conditions”—and I reckon that’s the pick of the week for a patient surfer. Crowds are possible here, so get in early.

Now, hold onto your board—Sunday the 9th of August throws a monster. The morning sees a 15ft SSW groundswell with a 13-second period and a combined energy reading of 10219. That’s very strong wave energy. But it’s too big for Rivermouth—this is a beginner break, and that’s expert-only territory. It’ll be closing out and dangerous. The afternoon drops to 8ft, still big and cross-shore. Unless you’re charging heavy water, give it a miss.

The following week gets quieter. Monday the 10th has a so-so 6ft S swell with light wind, but Tuesday the 11th is a little surprise: glassy conditions, a clean 3ft S swell with a long 13-second period, and combined energy at 560. That’s a fun, clean morning for a longboard or a fish. Wednesday the 12th and Thursday the 13th see some cross-off wind and chest-high E swell, but the wind picks up again Friday and Saturday, turning it choppy.

So, if you want the best of the run, set your sights on Saturday the 8th of August afternoon at Rivermouth. That’s the cleanest, most user-friendly window. After that, the big Sunday swell is one for the hardcore only, and then it fades into average. No surf for the first few days, but then it gets going.
