The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a long 16-day window for Riviera, and I’ll be straight with you – it’s a bit of a flat spell with a few glimmers at the very end.
The overall pattern is a drawn-out run of small, weak, and mostly messy SSW swell. For the first ten days or so, we’re looking at waves around 2 ft to 4 ft at best, but the quality is a struggle. The water, by the way, is running a very unusual 3° warmer than normal for this time of year at 74°, so it’s like a warm bath out there.
Let’s walk through it. Starting Saturday, August 15th, we see a 4 ft SSW swell with a long 16-second period, but the wind is a gentle cross-onshore from the west at 9 mph, making it feel choppy. Wave energy is moderate at 774, but the conditions are marginal with questionable tides. It’s really just a paddle-around spot for beginners if you’re keen.
Sunday the 16th is similar – a drop to 3 ft with a light cross-onshore.
Monday the 17th through to Thursday the 20th sees the swell drop under 3 ft, and while the wind turns light and onshore from the SW for a few days, the waves are tiny. Don’t get excited. The combined energy dips to the 300s and 400s. This is weak stuff.
From Friday, August 21st through to Sunday, August 30th, the story is more of the same: small SSW to SW swells, 1 ft to 2 ft, with mostly onshore or light cross-onshore winds. The period stays solidly in the 13 to 19 second range, which is proper groundswell, but there’s just not enough height to do anything with it. The energy values stay in the 100s and 200s – that’s weak.
Now, here’s the small standout. Look ahead to the last few days. Friday, August 28th, afternoon, we get a pulse: swell jumps to 4 ft from the SSW at a 16-second period, and the energy hits 1044 – that’s moderate wave energy. Still, the wind is a gentle cross-onshore from the west at 9 mph, which keeps it from being perfect. It’s marginal, but for the first time in a fortnight, there’s something with a bit of push.
Saturday morning, August 29th, is your best bet. We’ve got 4 ft from the SSW at an 18-second period, dropped to just a light breeze from the WSW at 6 mph. That’s a light cross-onshore, but close to glassy. Energy is 972, which is solid. It’ll be a little straight at a beach setup with that period, but for a beginner-friendly, very consistent break, it’s the cleanest window in the whole outlook. This is the one to pencil in.
The rest – Saturday and Sunday the 30th – don’t offer much. Sunday morning has a 3 ft SSW swell but with a southerly wind changing things up, and the energy drops back to 643.
Look, this isn’t a classic Riviera run. The good news is it’s a very consistent break, so when the swell does return, it’ll be rideable. But there’s a long stretch from August 17th through to the 27th where the waves are too small to really recommend. Keep an eye on that last weekend in August.
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.
