The Lowdown
Alright, Rusty here, let's talk about what's coming up for the Riviera Shorebreak.
First thing you need to know, this spot is a rare bird—it doesn't break often, so when it does, you pay attention. The water is sitting at a very warm 89°F, which is over two degrees warmer than usual for this time of year. That's notable, you'll feel it.
The pattern starts on Friday the 28th of August, and honestly, it's a slow start. The swell is there, but the wind is tricky. The best looking window isn't really until Saturday afternoon. That's when the wind goes glassy with a solid 4ft SW groundswell. The period is a long 16 seconds, so that's proper energy moving through, and the combined energy is a moderate 924. This is a rare, clean setup for a spot that doesn't line up often. Saturday afternoon is the standout of the whole run.
Sunday morning is rideable, but the wind is onshore, and the swell period drops to 14 seconds. The energy is still there, but it's not as clean. The rest of the first week is a mix of small, weak swells and cross-onshore winds. Nothing to get excited about.
Then there's a gap. From Monday the 31st of August all the way through to Friday the 4th of September, the conditions are marginal or poor. The swell is small and the wind is never right. You're looking at a real dry spell.
The next real chance comes on Saturday the 5th of September. The afternoon sees a 4ft SW swell with a 16-second period, and the wind is a light cross-onshore. It's not perfect, but it's better than the junk before it. Then, on Sunday the 6th of September, the morning goes glassy again with a 4ft SW groundswell at 15 seconds. That's another clean moment, but the swell is a touch smaller. Even so, for a spot that rarely breaks, a clean 4ft is a gift.
The second week tails off into smaller, weaker swells and more cross-onshore winds. The energy drops, the periods drop, and the wind gets messy. There's nothing that stands out after that Sunday the 6th. The forecast is less certain out there, but as it stands, the surf looks poor for the rest of the run.
So, to wrap it up: if you're going to paddle out, make it Saturday the 29th of August afternoon or Sunday the 6th of September morning. Those are your windows. The rest of the 16 days is mostly a waiting game for a break that doesn't fire often.
Rusty out.

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.
