The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at Rivermouth over the next sixteen days.
We’re starting slow. The first couple of days are a total mess – choppy and not worth the drive. But then things turn around. The best window is from Thursday the 30th of July through Monday the 3rd of August. That’s where you want to be.
Thursday morning the 30th is looking good – clean 6ft swell from the ESE with a light cross-offshore breeze. The combined energy is moderate (980). That’s a solid session. Then Friday morning the 31st of July is a standout – dead glassy, 5ft swell from the ESE, and moderate energy (560). It’s smaller but the conditions are absolutely perfect. That’s the pick of the batch.
Water temp is about normal for this time of year, so no need to overthink the wetsuit. Rivermouth is a beginner-friendly spot, very consistent, and with an S optimum swell direction, the ESE swell we’re getting on Friday will be a bit off-angle but still a lot of fun. Crowds can show up sometimes, so get in early.
The weekend of the 1st of August has a 6ft to 7ft E swell, but the wind is cross-shore and stronger, so it’s not as clean. Sunday the 2nd of August has a very long period 21-second SSW swell, but it’s only 2ft to 3ft, so not much punch.
The real standout is Monday the 3rd of August. Glassy conditions in the afternoon with a 3ft SSW swell and a 15-second period. Combined energy is moderate (535). The wind is calm, dead flat. That’s a classic, easy day at Rivermouth. Perfect for everyone.
Looking into the second week, it’s more mixed. The morning of Saturday the 8th of August is glassy with a 7ft S swell, but the period is short at 8 seconds, so it’ll be a bit lumpy. That’s for the more experienced crew. Sunday the 9th of August is clean with a 6ft SE swell, also short period, but the cross-offshore wind keeps it tidy.
Then we get a big one. Monday the 10th of August has a 10ft E swell, and the combined energy is strong (1523). That’s a lot of power. For a beginner-friendly spot like Rivermouth, that’s going to be way too big and dangerous. It’s an expert-only day, and even then, the cross-shore wind means it won’t be perfect. Best to watch that one.
The rest of the second week has some clean mornings and lumpy afternoons. Nothing to write home about, but a few glassy windows could be worth a quick session.
Lock in Friday the 31st of July or Monday the 3rd of August. That’s your best bet for clean, fun waves.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
