The Lowdown
Alright, Rusty here again, same story but in feet and knots for you imperial folks. Riviera Shorebreak is a rare one to catch breaking, so don’t expect much. The first decent waves show up around Saturday the 14th of September, but it’s tiny—2ft swell from the southwest with a side breeze. Not worth paddling out. The real action starts Monday the 16th and builds through the week. Wednesday the 18th morning brings the biggest swell: 4ft from the SW with a 16-second period, giving it some punch (moderate energy at 736). That’s the standout of the first week. Water temp is 90°F, which is much warmer than usual—over 4°F above normal—so it’s like bathwater. Thursday the 19th morning also offers 3ft SW swell with a 14-second period (577 energy) and light offshore wind from WSW, so those waves will be clean.
But the absolute best session is Saturday the 21st of September morning: 3ft SW swell with a 19-second period, which is a very long groundswell. Combined energy is 815, solid. The wind is light cross-onshore, but that long period and the swell direction matching the optimum mean decent shape. That’s the pick of the whole forecast. Sunday the 22nd morning is similar (3ft, 17 seconds, 627 energy) but not quite as good.
Into the second week, from the 23rd to the 27th, waves drop to 2–3ft with periods of 12–15 seconds, energy in the 200s to 400s. The best of that late run is Wednesday the 25th morning: 3ft SW, 14 seconds, 319 energy, light cross-onshore. Still marginal. The last day, the 27th, has tiny 2ft swell with a 17-second period but choppy wind.
So for a rare break like this, target Wednesday the 18th morning or Saturday the 21st morning. Small but rideable, and you’ll have the place mostly to yourself. Catch it when it’s on.

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.
