The Lowdown
Alright, surfers, Rusty here with a look at what Riviera's got cookin' over the next couple of weeks. Gotta be straight with you – this stretch looks like more of a patience tester than a head-turner. There's nothing that truly screams "drop everything and go." We're looking at a whole lot of marginal conditions and poor surf forecasts right from the start, with a few fleeting moments that might just be worth a paddle if you're desperate.
The water temp here is about average for this time of year, so no major surprises there.
We kick things off on Thursday, the 10th of September. Riviera is showing a 3ft SW groundswell, with a long period of 17 seconds and a combined energy of 628 (moderate). That's a solid pulse of energy, but the wind is a light cross-onshore breeze. It'll be clean enough for a beginner-friendly wave, but nothing to rave about. That tiny window of opportunity fades fast. By Friday morning the 11th, the wind picks up to a gentle cross-onshore and the conditions get choppy. Honestly, from Friday right through to Sunday the 13th, it's a write-off.
We see a bit of a dip in energy and a lot of poor conditions. A slight bump appears on Monday the 14th morning with a 3ft short-period wind swell (8 seconds, 305 energy), but the wind is a moderate cross-onshore breeze. That’s pure chop. Not worth it for a paddle board. It stays pretty lifeless and messy through the middle of the week.
Now, looking further out, the best bet in this whole outlook is probably the morning of Saturday the 19th of September. We've got a 3ft SW groundswell with a nice 18-second period, and the wind is forecast to be light and directly onshore. The combined energy sits at 522 (moderate). The wind being straight onshore isn't ideal, but it's light, so the surface could be glassy clean. It's the most promising of a flat-looking bunch.
There's also a slight uptick on Monday the 21st of September afternoon, with a 3ft SW swell (17 seconds) and 638 energy (moderate), again under a light cross-onshore breeze. It’s another marginal call, but one of the better-looking ones in this run. For you long-range planners, the morning of the 26th of September also looks okay on paper with a 3ft SW swell and offshore wind, but we’re talking a week and a half away, so keep your expectations flexible.
Overall, it’s a quiet outlook for Riviera. Most days are blown out or just too weak. The best you can hope for is a glassy, clean session on one of those marginal days with the long-period groundswell. Don't expect any barrels. Keep an eye on that light wind window; that's your only real chance.
Stay patient, Rusty.

Information about the Riviera Surf forecast
The above surf forecast table for Riviera provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Riviera can be found by selecting the local surf guide option on the grey menu. Our Riviera 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) 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 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.
Riviera is 2 km (1 miles) from San Clemente. If you plan a vacation in Orange County, look for hotels and other accommodation in San Clemente. San Clemente has rooms for a wide range of budgets as well as car hire and transport links.
