The Lowdown
Howdy, Rusty here. Let’s be real—this stretch is looking dead for the next week. From now through the 26th of August, there’s nothing rideable. It’s all cross-onshore chop, messy waves, and poor surf quality. Don’t bother waxing up yet.
Water temp is 80°, which is right around normal for this time of year, so at least you won’t freeze while you’re watching the flatness.
Things start to stir on the 27th and 28th of August, but it’s only marginal. Swell pushes to around 5ft from the E with a long 18-second period—that’s real groundswell energy (combined energy around 1580–1725). Problem is, the wind stays cross-onshore from the E at 12 mph, so it’s going to be lumpy and messy. The long period helps, but it’s not going to be clean.
The one standout is the morning of the 30th of August. We’re looking at 8ft from the ENE with a 13-second period, and the combined energy jumps to 2452—that’s strong and mean. Wind is more cross-shore, which is a bonus, but the afternoon drops to 10ft of shorter-period ENE slop, so you gotta be out there early. This is big and powerful—expert territory only. And since this spot is inconsistent and exposed, it’s not for the faint of heart. Crowds are possible, so don’t expect a private session.
There’s also a hint of a 19-second pulse on the afternoon of the 26th, but it’s tiny and messy—not worth the paddle.
Bottom line: if you’re serious, mark your calendar for the morning of the 30th. That’s your best shot in a rough stretch. Otherwise, might be time to dust off the kite gear—there’s plenty of wind, just not much surf.
Rusty.

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