The Lowdown
Alright, Rusty here again. Let’s look at the Riviera Shorebreak in feet and inches.
Over the next 16 days, this is a spot that almost never breaks, so you’ll need to be patient. First surfable waves show on Thursday the 27th of August. Swell is about 2.3ft from the SW, with a long 15-second period and a light offshore W wind, around 10 km/h. The water temp is 31.7°, which is about 2.1° warmer than normal for this time – that’s notable. Energy is moderate (435). But the forecast calls it marginal, so don’t get too excited.
Friday the 28th: still small, 2.6ft to 3.6ft, but the swell period jumps to 16–17 seconds. That’s real groundswell energy. Morning wind is cross-on and choppy, but it goes light offshore in the afternoon. Energy hits the 800s.
Saturday the 29th is your best shot. Morning gives you 4.9ft of SW swell with a clean, light offshore WSW wind and a 16-second period. Combined energy jumps to 1141 – that’s moderate to strong. This is the standout. It’s not giant, but for a rarely-breaking wave, that’s a window. Afternoon gets slightly bigger at 5.2ft but wind picks up.
Sunday the 30th fades: swell back to 3.9ft–4.3ft, shorter period, cross-on wind. Not great.
From Monday the 31st through mid-week in September, it’s mostly under 3ft with weak, cross-onshore winds. A few days show no surf.
There’s a possible window around Thursday the 3rd of September into Friday the 4th. Swell builds back to 3.3ft–4.3ft, with a very long 18-second period on Thursday. Morning has light offshore WSW wind, energy around 859. Could be clean but still marginal.
After that, from September 5th to 11th, it’s a long stretch of small swells (2.6ft–3.6ft) with light or cross-onshore winds. Most days are marginal or poor. No real gems in that second week.
Crowds can show up sometimes, but with it breaking so rarely, you’ll probably have it quiet. Best advice: if you’re going, make it Saturday the 29th of August morning. After that, you’re waiting for a hopeful session around the 3rd or 4th of September.

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.
