The Lowdown
Alright, listen up. We got a 16-day forecast that’s mostly a whole lot of nothing, with a couple of tiny windows that are worth setting an alarm for. It’s not pretty, so let’s cut to the chase.
Right off the bat, Friday the 7th is a no-go. There’s some swell, but it’s short-period junk with cross-shore wind. Forget it. Your first real chance is Saturday morning, August 8th. The stars align for a bit: we’ve got clean, 1.2m waves from the SSW with glassy conditions. That’s your window. The energy is building, showing a combined 618, but it’s moderate. Get out there early because the afternoon wind is going to wreck it.
Sunday the 9th starts with a little more size at 1.5m, but there’s a fresh breeze on it, making it rough. Then the forecast goes south for a while. From Sunday afternoon through the middle of the week, we’ve got a solid stretch of poor conditions. We see a bigger pulse on Monday the 10th with 2.5m in the morning, but it’s got rain and bad wind with it. That’s getting too big for anyone but the experts, and the quality just isn’t there. That 2.5m is over the beginner limit, and the period on Sunday is a terrible 7 seconds. The energy on Monday morning is strong, hitting 1558, but it’s not going to be clean.
From the 11th through the 14th, it’s a mess. Onshore winds, mushy short-period swell, and a lot of “poor” flags. There’s a little bump on the 11th and 12th, but the wind is wrong and it’s not happening. By the 13th and 14th, the swell just dies, and we’re left with dribble.
The second week is even leaner. There’s a tiny window on Sunday afternoon, the 16th, when the wind goes dead calm. We get a clean little 0.9m wave from the E, with energy at 229. It’s weak and small, but it might be the cleanest wave of the whole damn forecast. Then it goes quiet again until Wednesday morning, the 19th. Again, glassy conditions but with a weak 0.7m SSW swell. Tiny, but clean.
The final few days of the window are just a write-off. The swell tries to pick up on the 21st and 22nd, but the wind is screaming from the WSW at 30-35 km/h. That’s a cross-offshore wind, but at that strength, it’s just blowing the tops off everything. For a break like Rivermouth, that just makes it a mess and, honestly, it might be more interesting for kite surfing than paddle surfing at that point.
So, the one true standout is Saturday morning, August 8th. Clean, 1.2m, glassy, with that long 14-second groundswell period. That’s your best bet. The other little clean windows on the 16th and 19th are for the diehards who just need to get wet on something. Don’t get your hopes up for much else.
Also, the water is much colder than normal for this time of year. It was sitting at about 18° on the 7th, which is over two degrees colder than average. That’s a big deal, so dig out the thick rubber.
Get on it Saturday morning. Otherwise, you might be waiting a while.

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.
