The Lowdown
Alright, this is Rusty. Let’s have a look at what’s on offer for Rivermouth over the next couple of weeks.
To be honest, the first few days are a bit of a write-off. We’ve got some swell, sure, but the wind is a mess – cross-shore and cross-onshore junk that’s ruining any chance of a clean wave. The water is sitting at 64°, which is a solid 4° colder than normal for this time of year, so you’ll want a thick suit. It’s not until Saturday, August 8th that things finally click. That’s the standout window in the near term. We’ve got a clean 4ft swell from the SSW, period at 14 seconds, and a light offshore breeze from the NNW. The combined energy is moderate (700), and the conditions are described as clean. That’s your window for a good session at Rivermouth. It’s a beginner-friendly spot, very consistent, and while the swell direction isn’t perfectly aligned with the optimum S direction, it’s close enough to work. Crowds are possible, so get there early.
The weekend after that gets blown out again. Sunday the 9th sees the swell jump to 6ft, but with a fresh 22 mph crosswind, it’s just a mess. Monday the 10th, the swell hits 10ft from the SSE with a short 9-second period, which is too big for this break and the onshore wind will make it ugly. That combined energy is a strong 1441, but it’s not for paddling.
The next real glimmer of hope comes late in the window. Tuesday morning, August 18th, we get glassy conditions with a 5ft easterly swell, period at 9 seconds. The combined energy is moderate (436), and the wind is glassy – that’s a major positive. The swell direction from the east isn’t the optimum south, but with clean conditions, it’ll be rideable. Then Wednesday morning, August 19th, we get another glassy morning with a smaller 3ft swell from the east, period at 9 seconds. The energy is weak (262), but for a clean, small wave session, it’ll be fun. Keep in mind, these are longer-range calls, so they’re a bit less certain, but they look promising. The rest of the time is a mix of marginal conditions or poor surf with wind and chop, so those two mornings are your best bets.
Rusty.

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.
