The Lowdown
Alright, let’s break it down for Riviera Shorebreak. Over the next 16 days, it’s a tough stretch. This spot rarely breaks, and we’re not looking at any real gems here.
Starting Thursday the 10th of September, we get a 4ft SW groundswell with a long 16-second period, but it’s crossed by a light south wind. Combined energy is moderate (611), and the wave call is marginal. No good. Afternoon drops to 3ft and gets worse.
Friday the 11th and into the weekend, the swell drops to 3ft by Saturday afternoon, with period down to 14 seconds. Winds stay cross-on or onshore most of the time. Energy gets as low as 263. Poor stuff.
Monday the 14th gives us 2ft SW swell with an 18-second period, but it’s onshore. Energy is weak (281). Not worth suiting up.
Wednesday the 16th morning improves a little – 4ft SW, 16-second period, light onshore wind, energy at 680. Still marginal. With this spot being inconsistent, it’s a long shot.
The best chance comes Sunday the 20th and Monday the 21st. Sunday morning has 3ft SW swell, a very long 19-second period, near-calm wind, and combined energy of 823 – the most energy we see. Monday morning is similar: 4ft, 17 seconds, light cross-on breeze, energy at 805. That’s the pick. But with that long-period groundswell, it can go straight at a beach break, and the wind is never truly offshore. It’s promising but not a sure thing.
After that, the final week fades into 3ft slop with poor or marginal conditions. No standouts.
Bottom line: no day is a true winner. If you’re itching, Sunday the 20th or Monday the 21st mornings are the only real windows, and even then, it’s a gamble. This area can go flat for stretches, and this looks like one of those times. Keep an eye on the forecast, but don’t hold your breath.

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.
