The Lowdown
Alright, crew, it’s Rusty here. Let’s be straight about this—the next couple of weeks look pretty grim for Riviera Shorebreak. Don’t get your hopes up for anything special. We’ve got a long, slow slide into small, messy surf.
The first real chance to even look at the ocean comes Thursday the 3rd of September. There’s a solid groundswell rolling in, about 4ft from the southwest with a very long period of 18 seconds, packing moderate wave energy (1259). But here’s the kicker—the wind is cross-on from the west-northwest at 12 mph, and the report is calling it marginal with choppy conditions. The water is way warmer than usual for this time of year at 89°, which feels weird, but it doesn’t make the surf any better. Friday the 4th holds similar size, 4ft from the southwest with 16-second periods, but the wind stays cross-onshore and choppy.
The swell sticks around through Saturday morning the 5th, still 4ft from the southwest, and we finally get a clean offshore wind from the southwest at just 6 mph. That’s the one bright spot in this whole outlook—it’s the most promising session on offer, though the wave comment still calls it marginal. The wave energy is still moderate (1211). After that, it fades.
Sunday the 6th drops to 4ft with a 15-second period, but it’s cross-on again. By Monday the 7th we’re down to 3ft, and the wind is cross-shore. From there it’s a steady decline. Tuesday the 8th we barely see 3ft, and it’s barely worth paddling out. For the rest of the first week and into the second, the swell stays under 3ft, period drops, and the wind keeps it messy or glassy but tiny.
There’s a Sunday the 12th morning that stands out because the wind goes glassy, but the swell is only 3ft with 14-second period—so it’s clean but small. That’s something for a log or a big board.
The only other moment that catches my eye is way out on Thursday the 17th of September. The swell picks up a little to 2ft, but the period jumps to a very long 22 seconds, and energy climbs back to moderate (517). The wind is offshore in the morning from the west at 6 mph, which would make it clean. But it’s tiny and far out, so I wouldn’t book time off work for it.
Honestly, there are massive gaps here—days and days with no decent surf at all. Riviera Shorebreak rarely breaks consistently on its best days, and this stretch is no exception. If you’re desperate, the Saturday morning the 5th or that glassy Sunday the 12th morning are your best shots, but they’re nothing to write home about. For experts only when it’s over 5ft, and that never happens here.
Keep your expectations low and your wax soft.

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