Table - best surf conditions forecast for The Rivermouth over the next 16 days.
Alright mates, Rusty here again, now in feet and miles. The Rivermouth – a sandbar wave that almost never breaks, and when it does the local crew is all over it. Advanced only. Water temp right now is a balmy 62°F, a full 5°F above normal – that’s way warmer than usual for this time of year.
Looking at the whole 16-day window, it’s mostly quiet. The first week has small, waist-high SSW swells around 2–3 ft with light cross or cross-onshore breezes. Not enough to get the sandbar working properly. Friday the 10th and Saturday the 11th see a switch to shorter-period WNW swell, up to about 6 ft, but the wind stays cross-on and the waves are messy. Energy values in the 600–800 range – moderate, but not clean.
Then we get a couple of glassy windows in the second week. Wednesday 15th July afternoon – flat calm wind, 5 ft of WNW swell at 8 seconds. Energy 486, clean surface. That’s a session for the experienced, knowing this spot hardly ever holds a lineup.
The real gem is Thursday 16th July afternoon. Swell hits 6 ft from the WNW, 9 seconds, and the wind goes glassy again. Energy jumps to 1096 – strong for this sheltered sandbar. Sure, the direction isn’t the ideal SSW, but with clean conditions and a decent push, the river mouth could offer some fun waves. At 6 ft it’s definitely expert-level. After that, it fades back to small, onshore mush. The 16th is the one to aim for, but as always with a forecast that far out, keep your fingers crossed and watch the updates.
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.
