The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for The Rivermouth over the next couple of weeks.
First off, we’ve got a bit of a wait on our hands. The early part of the outlook is a bit of a struggle, with the first decent window not showing up until Wednesday the 29th. The Rivermouth is a sandbar setup that rarely breaks, so we need the stars to align, and honestly, for the first few days, they just aren't. The water is sitting at a touch warmer than normal for this time of year, about 60°F.
Now, Wednesday the 29th of July is where it gets interesting. The afternoon session is the standout in this whole forecast. We’re looking at a 4ft SSW groundswell with a very long 16-second period pushing a moderate wave energy (1068). The wind is forecast to go glassy. That’s a major positive. A long-period swell like this at a sheltered river mouth can set up some proper lines, and with zero wind, it’s going to be clean. The swell direction is right on the money from the SSW. This is the best on offer, no question.
Thursday the 30th of July afternoon is another solid option. The swell drops a touch to 3ft, still from the SSW with a long 15-second period. It's not as powerful, but the wind is glassy again, so you’ll still get some fun, clean ones. The combined energy is moderate (945).
You then get a mix of conditions through the end of July and into the start of August, but nothing really jumps out as epic. The afternoon of Saturday the 1st of August sees a new pulse of swell, 6ft from the WNW, but with a short period of 9 seconds. That’s more of a windswell, and while it’s glassy, the short period at a beach-sandbar break can make for a bit of a lumpy, less organised wave. It’s an option for the more advanced crew, but not the standout.
After that, things get pretty grim. From the 4th of August onwards, the forecast takes a real dive. The wind shifts onshore, the swell drops in size and period, and the quality goes out the window. We’re looking at a long stretch of marginal to poor conditions that lasts for over a week. The combined energy drops to weak levels, and the setups just aren't there.
So, to sum it up: your best bet is the Wednesday afternoon (29th July) and the Thursday afternoon (30th July) at The Rivermouth. Get it while it’s good, because after that, it’s a waiting game.
Rusty.

Information about the The Rivermouth Surf forecast
The above surf forecast table for The Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Rivermouth can be found by selecting the local surf guide option on the grey menu. Our The 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 (The 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 The 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.
