The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for our stretch of coast. Honestly, I gotta be straight with you – this is a tough one. We've got a solid run of small, weak swell and a lot of onshore or cross-onshore wind. The wave energy is in the doldrums for the first week and a bit, so don't go getting your hopes up for anything special. There's a long, quiet stretch ahead before we see even a flicker of decent potential.
The only spot in the mix is Surfside Jetty. It’s an inconsistent, advanced-level break that's fairly exposed to the west, but the conditions we're looking at are pretty grim. The water temp is sitting at a very unusual 72°, which is much warmer than normal for this time of year – a real anomaly.
We kick off on Saturday the 8th of August. Morning has a small 2ft SSW swell, with a long 17-second period, but that cross-on wind from the WSW at 10 km/h has it all messy. Combined energy is weak at 287. The afternoon gets worse with the breeze picking up to 20 km/h, making it choppy. This pattern pretty much holds all through the first week. Sunday the 9th through to Saturday the 15th is just more of the same: tiny waves, poor surf conditions, and combined energy readings mostly under 500 – that’s weak, with a few days barely scratching moderate. On Friday the 14th, the morning shows a marginal sign of life with a 2ft, 19-second period SSW swell and a combined energy of 339, but the wind is still onshore and it’s only rated as a "marginal" call. Not worth rushing for.
The weekend of the 16th and 17th sees the swell trying to push a little higher, hitting 3ft on Sunday the 16th morning, with the combined energy climbing to 484 – that's the most we'll see in this whole stretch. But again, the wind is cross-onshore or onshore, ruining any chance of clean waves. Monday the 17th morning is another marginal call with 3ft of SSW swell and a 14-second period, but it's still messy.
We get into the second week, and things stay poor. Tuesday the 18th afternoon brings a weird spike in swell height to 4ft from the west, but look at the period – a shocking 7 seconds. That's just wind chop. The combined energy is moderate at 422, but with that short period and 20 km/h onshore wind, it’s a complete write-off. The rest of the run from Wednesday the 19th through to Sunday the 23rd is a total bust: tiny 2ft to 2ft SSW swell, cross-onshore wind, and weak combined energy. There’s nothing here to get excited about.
Forget the paddle; with this constant cross-onshore wind and small, weak swell at a beach setup, this looks way more interesting for kite surfing than a traditional paddle session.
Look, it's a blank run. There are no standout days, no hidden gems. With this being an inconsistent break, a long quiet spell like this is pretty normal for the area. Forecasts can change, so keep an eye out, but for now, save your energy.
Rusty.

Information about the Surfside Jetty Surf forecast
The above surf forecast table for Surfside Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Surfside Jetty can be found by selecting the local surf guide option on the grey menu. Our Surfside Jetty 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 (Surfside Jetty) 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 Surfside Jetty 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.
Surfside Jetty is 4 km (2 miles) from the city of Seal Beach. If you plan a vacation in Orange County, look for hotels and other accommodation in Seal Beach. Seal Beach has rooms for a wide range of budgets as well as car hire and transport links.
