The Lowdown
Alright folks, Rusty here. Let's get into it.
The story for the next couple of weeks is a bit of a slow burn, with a few windows of opportunity, but you'll have to be patient. The first real swell worth talking about is a solid pulse from the SSE that lines up on Tuesday, July 28th.
The standout session is clearly Tuesday morning, July 28th at Rivermouth. The swell will be a solid 8 ft from the SSE with a short-period of 8 seconds, pumping the combined wave energy up to a strong 1229. That's right in the zone for some power. The best part? We've got a light onshore wind from the SSE, keeping the surface a little bumpy, but it's workable. This is a beginner-friendly break, so it's a good option for the crew looking to step up into some bigger waves, but just be aware that 8 ft is getting a bit big for total beginners. The water temp is currently 67°F, which is about 2° cooler than normal, so nothing crazy, just a touch of the winter chill.
The next small window shows up on Thursday, July 30th. The morning session has a 5 ft swell from the East with a 9-second period, and the wind is light and offshore from the NNE, promising clean conditions. The combined energy is moderate at 586. It's not a huge day, but it's a nice, clean option for a paddle.
After that, things get a bit messy with strong cross-shore winds for a few days, but a serious pulse of long-period energy is on the horizon. Tuesday, August 4th, in the afternoon is looking very promising. Rivermouth will see a 8 ft swell from the East with a very long 12-second period. The combined wave energy is a massive 3403, meaning serious power. The wind is light and cross-shore, so it'll be clean. This is a pulse of groundswell. At 8 ft, you really need to be an experienced surfer to handle this. The long period will make for some beautiful, well-shaped waves, but it might be a bit too straight for the beach break here, so keep that in mind.
Saturday morning, August 8th, is another one to file away. It's a smaller 5 ft swell from the SW, but the wind is offshore and the conditions are looking clean and glassy. Perfect for a longboard or a funboard.
To sum it up: The best on offer is the Tuesday morning, July 28th, for the first big push, and the Tuesday afternoon, August 4th, for the long-period groundswell experts session. The Thursday morning, July 30th, and Saturday morning, August 8th, are the clean, smaller windows.

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.
