The Lowdown
Alright, grab a coffee, let’s talk Riviera. This is a beginner-friendly, very consistent spot that’s exposed to the SW. The whole 16-day window is dominated by small, onshore-angled swell and light to moderate cross-onshore wind. The water temp is about average for this time of year, so nothing wild there. We’re looking at a long stretch of pretty ordinary conditions.
The first few days are a write-off. Wednesday the 12th through to Thursday the 13th is all poor surf, with weak SW and SSW swell around 2ft to 3ft and a long period of 16–17 seconds (good energy at 282–482 in the combined energy, but with the wrong wind direction it’s a mess). Friday the 14th morning shows a glimmer – a 2ft SSW swell at 18 seconds and light WSW wind – but it’s still only marginal, with the wind on. That combined energy reading of 556 is moderate, but the surf quality is just not there.
Saturday the 15th and Sunday the 16th sees the swell nudge up a bit – 3ft to 4ft from the SSW/SW, periods around 15–16 seconds. The combined energy climbs into the 570–725 range, which is moderate to strong energy. Still, the wind is cross-onshore or onshore from the W or WSW, so the surface is going to be choppy or at least rippled. Saturday afternoon has a 4ft swell and onshore wind – not clean for a beginner spot. Sunday morning gets the best score of the whole run, with light cross-onshore wind and a 4ft SW swell at 16 seconds. It’s marginal at best.
After that, from Monday the 17th onward, it’s a slow decline. Swell sizes drop back to 2ft–3ft, periods stay between 13 and 18 seconds, but the energy weakens (210–512 range) and the wind is consistently cross-onshore. There’s no real standout day. A few mornings, like Wednesday the 19th and Wednesday the 26th, show marginal surf with light wind, but the swell is tiny and the quality is low. The whole second week is pretty much the same – small, onshore-angled, and not worth getting excited about.
For a surfer, the best bet – and I’m stretching here – is Sunday the 16th morning. A 4ft SSW swell at 16 seconds (groundswell, so longer gaps between sets, which helps a beginner paddling out) with light cross-onshore wind. The combined energy is 570, moderate. It’s still not clean, but it’s the least messy option in the whole 16 days. Even then, it’s only for the patient beginner who doesn’t mind a bit of wind bump. Every other day is either poor or marginal.

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.
