The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for Rivermouth over the next couple of weeks.
We’ve got a bit of a slow start, but then things get interesting. The first real standout is Tuesday morning, July 21st. It’s glassy, crystal clear, with a clean 4 ft swell rolling in from the SE. The water is sitting at 64°, which is much colder than normal for this time of year, so you’ll want a good thick wetsuit. The wave energy is solid (671), and the period is a decent 11 seconds, so there’s enough push for a fun, clean session. This is beginner-friendly, and Rivermouth is very consistent, though you might see a few others out there as crowds are sometimes an issue.
Tuesday afternoon sees a drop in height to 3 ft, and wind swings to a light cross-onshore, making it less appealing. Wednesday morning has a bit more size at 4 ft, but the cross-shore wind messes with the surface. Skip it. Wednesday afternoon, though, glass goes back on with a 3 ft SE swell and a 12-second period – that’s a nice little window. The energy is still moderate (611).
Thursday morning (July 23rd) is a write-off with stronger wind and chop. Thursday afternoon is even worse. Friday the 24th is a big one to watch, but not for the faint of heart. Morning shows a solid 6 ft from the SSW with a very long 18-second period, and the energy jumps to 2199. That’s strong, powerful groundswell. The wind is messy, though. The real action on Friday is the afternoon: 7 ft from the S with a 16-second period, and an offshore breeze from the ESE. That’s a heavy, clean wave. Anything over 8 ft is expert territory, so at 7 ft, it’s still manageable for strong intermediates, but it’s definitely not for beginners. This is a big, powerful swell (energy 2541).
Saturday the 25th cleans up again. Morning is glassy with a 5 ft SSW swell, 14-second period. That’s a beautiful, clean session right there. The energy is moderate (861). Afternoon gets a bit wind-affected. Sunday the 26th has a morning cross-off breeze, but the swell drops to 4 ft, so it’s cleaner but smaller.
The next week is quieter. Monday the 27th is poor. Tuesday the 28th morning is glassy but small, only 2 ft, though the long 13-second period groundswell (energy 418) will make for some fun little waves on the river mouth. Wednesday the 29th sees a bump back up to 5 ft from the SSW with a 15-second period and a cross-shore wind, making it tricky. The energy is strong (1599). Thursday the 30th has a cross-off wind and a 5 ft S swell, but the period drops to 13 seconds. It’s okay, nothing special.
Towards the end of the run, conditions get messy with rain and strong wind. August 1st has a fresh cross-off breeze but the swell is small. August 2nd and 3rd show some longer-period E swells, which can be a bit straight at beach breaks, but for a river mouth like this, they might offer some fun lines. The best bet in the second week is probably Wednesday, August 3rd morning: a clean 4 ft from the E with a light cross-off wind. The energy is low (439) and the period is short (9 seconds), so the waves will be weaker, but it’ll be clean.
The standout of the whole outlook is Friday, July 24th afternoon. That 7 ft S swell, 16-second period, and offshore wind is as good as it gets in this window. The second best is Tuesday morning, July 21st, for a clean, glassy, beginner-friendly session.
Rusty, signing off.

Information about the Rivermouth Surf forecast
The above surf forecast table for Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
