The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Riviera Shorebreak.
The next couple of weeks are a bit of a mixed bag, with a lot of marginal conditions in the early going. The water temperature is sitting at 89°, which is a touch warmer than normal for this time of year – you’ll feel that extra warmth when you’re sitting out there.
The first few days are pretty grim. Thursday the 20th through to Sunday the 23rd are all showing poor surf conditions, with small swell around 2ft to 3ft and mostly onshore or cross-onshore winds. The energy is weak to moderate, with the combined energy reading between 173 and 411. Nothing to get excited about.
Monday the 24th still looks poor, with small 2ft to 2ft swell and cross-onshore winds. The energy is still moderate, around 308 to 359.
Then on Tuesday morning the 25th, we get a little window of hope. The wind turns glassy, and the swell bumps up to 3ft from the SSW with a period of 12 seconds. The combined energy is 410 – moderate. It’s the best of a pretty average run, and it’s the only time in the whole forecast where the wind is truly glassy. That’s your standout session for the first week. The afternoon goes back to poor with onshore wind.
Wednesday the 26th to Thursday the 27th are marginal at best, with onshore and cross-onshore winds, swell around 2ft to 4ft, and energy climbing to 574 on Wednesday morning. The period hits 16 seconds on Wednesday morning, which is a long-period groundswell, but the cross-onshore wind will mess it up.
Friday the 28th brings a bit more size – 3ft to 4ft from the SW with a 16-17 second period. The energy shoots up to 723 in the morning and 941 in the afternoon – that’s strong wave energy. The wind is cross-onshore though, so it’ll be bumpy. Still, the long period suggests there’ll be some push.
Saturday the 29th and Sunday the 30th are more of the same – onshore or cross-onshore winds, swell around 4ft to 4ft, and moderate to strong energy (788 to 904). The quality is still poor or marginal.
Monday the 31st to Wednesday the 2nd of September drop back to small 2ft to 3ft swell with cross-onshore winds and poor conditions. Energy is moderate, around 289 to 398.
Thursday the 3rd of September morning shows a 4ft SSW swell with a 12-second period, light onshore wind, and a strong energy reading of 836. It’s marginal, but it’s the best of the second week. The afternoon has a 3ft SW swell with a 17-second period and cross-onshore wind – clean energy but bumpy.
Friday the 4th of September morning has the biggest swell of the whole forecast: 5ft from the SSW with a 10-second period – that’s short period, so it’s a bit messy. The energy is 998, nearly into the very strong range. The wind is light cross-onshore, so it’s marginal. The afternoon drops back to 3ft with a 16-second period and cross-onshore wind.
Overall, the best bet is Tuesday morning the 25th with that glassy wind and 3ft from the SSW. After that, Friday the 28th and Thursday the 3rd of September have some size and long-period energy, but the wind is never perfect. Riviera Shorebreak rarely breaks, so even these marginal windows are worth keeping an eye on.
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.
