The Lowdown
Alright, Rusty here again. Let’s break it down for the imperial crew. This Riviera Shorebreak outlook for the next 16 days is a tough one. It’s a rare-breaking spot, and the numbers tell the story – we’re looking at a long blank run with no real standout days.
Starting Sunday, 6th September, there’s a 4ft swell from the SW with a very long 15-second period, moderate combined energy at 745. The water temp’s sitting at an unusual 90°, which is much warmer than normal for this time of year – that’s a real head-scratcher. But the wind is onshore from the W at 15 km/h (9 mph), and it’s called "marginal surf forecast or questionable tide conditions." Not a good start.
Monday morning, 7th September, drops to 3ft from the SW, 14-second period, with cross-shore wind from the S at 15 km/h (9 mph) and a slight chop. Energy down to 590. Monday afternoon is 3ft from the SSW with offshore wind from the SW at 10 km/h (6 mph), but still marginal.
The rest of the first week into the second week is a slow slide: small waves from 2ft to 3ft, mostly cross-onshore or onshore wind, with combined energy in the 250 to 640 range – weak to moderate. There’s a few moments with offshore wind, like Wednesday afternoon, 9th September – 3ft with a very long 17-second period – but energy’s only 490 and it’s still marginal.
The best we get is around the middle of September. Thursday morning, 16th September, has 3ft from the SW, 16-second period, offshore wind from the WSW at 10 km/h (6 mph), energy at 640. Friday morning, 17th September, is similar: 3ft, 14-second period, offshore wind, energy at 587. But both are labelled marginal. For a spot that rarely breaks, these are your best shots, but the quality’s not there.
After the 20th, it’s small stuff – 2ft to 3ft – with cross-onshore winds and energy under 650. Monday morning, 21st September, has 3ft, 17-second period, light offshore wind, and energy at 649 – still marginal.
Bottom line: there’s no day worth driving for. The consistent story is marginal surf, poor conditions, and a break that rarely works. If you’re into kitesurfing, some of those afternoons with 15-20 km/h (9-12 mph) cross-onshore wind and 2ft to 3ft swell might offer something, but for paddle surfing, this is a blank. Save your energy for a better forecast.
Rusty.

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.
