The Lowdown
G'day, Rusty here. Let's talk about what's brewing at Long Beach over the next couple of weeks.
Right now, the water's sitting at 58°, which is a bit colder than usual for this time of year, so don't forget your wetsuit.
We're easing into it with a slow start. The first decent windows open up on Monday afternoon (August 3rd) and Tuesday morning (August 4th). Monday arvo serves up a 4ft WSW swell with a 13-second period, and a clean cross-off breeze. The energy's moderate (964). Tuesday morning brings a clean 4ft SW swell on an offshore breeze, with moderate energy (463). Fun, small-wave days for the intermediate surfer.
The true standout is a window of excellent but powerful surf for experienced surfers only. Thursday morning, August 6th, is glassy with a 10ft SW swell, 13-second period, and very strong wave energy (3691). The offshore SSE breeze kicks in Thursday afternoon, keeping it clean with the same solid 10ft SW swell and 3651 energy. This is the pick of the whole run—big, clean, and powerful. But at 10ft, this is strictly for the experienced crew.
The weekend of August 8th and 9th turns ugly with strong onshore winds and lumpy conditions, so stay on the beach.
Then we get a second surge of giant swell from August 10th onwards. Monday afternoon (August 10th) sees a 15ft SW swell with a moderate breeze, but it's clean. The energy's massive (4664). The real monster hits Tuesday morning, August 11th, with a 15ft SSW swell, 14-second period, and extreme energy (12595). Tuesday afternoon delivers a 16ft S swell, 15 seconds, and 13106 energy. These are massive, but the cross-on wind and marginal conditions mean it's a dicey session for experts only.
By August 14th (Friday morning), we get a tidy 7ft SW swell, 16-second period, with a clean offshore SSE breeze and strong energy (3183). That's a solid, clean option for those who know what they're doing.
So, to wrap it up: the best on offer is Thursday, August 6th, for the big, clean, glassy swell. The second-week giants are for the fearless experts only. The gaps are short, but the conditions are hit and miss.
Stay safe out there.
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.
