The Lowdown
Alright folks, Rusty here. Let's be straight with you – this 16-day window for the Surfside Jetty area is pretty grim. The models are barely coughing up anything we'd call a wave, and honestly, it's a long stretch of nothing to get excited about. We're looking at over a week of poor conditions before we even get a whiff of a marginal wave. For a spot that's already inconsistent, this blank run is more normal than you'd hope, but keep your chin up – forecasts can change.
Alright, let's walk through it. The whole period starts off flat and stays that way. From Tuesday, August 11th, right through to the weekend, we're seeing tiny swell, 1ft to 3ft from the SSW and SW. The winds are mostly onshore or cross-onshore, making for choppy, poor surf. The combined energy is weak, mostly in the low to mid hundreds, and the guidance calls it "poor surf conditions" every single day until the 16th. That Saturday morning, the 16th, is the first time we see even a "marginal" call, with a 3ft SSW swell (16 seconds, 348 energy), but it's still light onshore wind. Not worth paddling out for.
The next week doesn't get much better. Through the 17th to the 22nd, it's still tiny. August 21st Friday afternoon shows a 4ft swell from the W, but the period is a crummy 6 seconds – that's pure wind chop, not a wave you want to ride. The energy is still weak. It's a beach and jetty setup, so with that significant swell but poor quality and onshore wind, this setup looks more interesting for kite surfing than paddle surfing.
The only glimmer of hope, and I mean a tiny one, shows up on August 25th and 26th. On Tuesday the 25th, we have a 2ft SW swell (18 seconds, 339 energy) with cross-onshore winds. The 26th Wednesday morning is similar: 2ft SW swell (16 seconds, 396 energy) with light cross-onshore winds. The guidance only rates these as "marginal". The swell direction is SSW to SW, which is not the optimum W direction this break needs to really fire. The period is decent, over 15 seconds, so it's a long-period groundswell, but at a jetty and beach break, these long-period swells can break too straight and be tricky. The water temperature anomaly is not provided, so we can't say if it's warmer or colder than average.
So, if you're desperate, keep an eye on that Wednesday morning, August 26th. The swell is small, the wind is light, but it's still cross-onshore. It's marginal, inconsistent, and crowds are often a problem here. The overall forecast quality is poor. There's no standout day in this entire outlook. It's a tough run for Surfside.
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.
