The Lowdown
Alright, Rusty here again, talking feet and Fahrenheit for this one.
Long Beach is playing its cards close to the chest. The water temp is about normal for the season, so you're not in for a shock.
There's a lull to start. Then Friday morning, August 28th, you'll see some waist-high waves from the south, cleaned up by a light breeze. It's a gentle start. Saturday, August 29th, is where it gets interesting. The morning is clean, but the magic happens in the afternoon. We're looking at a 7ft south-west swell with a long 14-second period. The wind is offshore, and the combined energy is pumping at 2621 (moderate wave energy). That's a clean, powerful surf for experienced folks. That's the one to aim for in the first week.
Sunday (30th) has size (8ft to 8ft from the SW) but the wind swings onshore and messes it up. Monday is weak and clean but not worth the drive.
Then, mark your calendar for Wednesday, September 2nd. That's a monster day. A 18ft south-west swell with a 17-second period, and an incredible combined energy of 16184 (very strong to strong wave energy). The morning offshore breeze will make it glassy. This is a big-wave day, for experts only. It's going to be heavy, powerful, and dangerous. It's a true standout, but you need to know what you're doing. The afternoon trades kick in, dropping the quality.
September 3rd and 4th are terrible. A near gale (50 mph winds) is blowing onshore, creating a horrific mess. This would be a kite-surfing spot, not a paddle zone. You'd be a fool to try.
The 5th and 6th are a mess of bad wind and shifting swell direction. The ocean is not playing ball.
The second week is much smaller. September 7th (Monday) gives you a clean, waist-high, 3ft south-west swell. A fun little morning surf. But then the wind comes back strong from the 8th on. There's a brief window on Thursday, September 10th: a 12ft SE swell with a short 8-second period. The offshore wind will make it clean, but it's heavy and steep for experienced surfers only. That's the last gasp of the second week before it fizzles out.
Rusty.

Information about the Long Beach Surf forecast
The above surf forecast table for Long Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Long Beach can be found by selecting the local surf guide option on the grey menu. Our Long Beach 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 (Long Beach) 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 Long Beach 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.
