The Lowdown
Alright, Rusty here. Let me tell you straight up – this is a tough stretch for Crouching Lion. We're looking at a 16-day window starting today, August 18th, and honestly, there's not a single day that's going to get the heart pumping for paddle surfing.
The whole pattern is written off: from this morning all the way through to the end of the forecast on September 2nd, the conditions are just plain poor. There's no standout session, no hidden gem to get excited about. The first recommendation doesn't even appear because everything scores a zero for quality.
Throughout the whole run, we've got a persistent cross-onshore wind from the east and east-northeast, blowing at 9 to 22 mph. This keeps the surface chopped up, lumpy, and messy. The swell direction is mostly coming from the east-northeast, which is off the optimum direction for this break – it really wants a northeast swell.
Even though the swell sizes build up, especially around late August, it's all for nothing with that wind. From August 22nd to the 25th, we see solid 5ft to 8ft of easterly swell with moderate to strong energy levels. But that's paired with fresh cross-onshore winds, making it a choppy, bumpy mess. A few of those days, the swell is over 5ft, so it's not for learners anyway, but it's still not good for anyone.
Then from August 26th into early September, the swell stays between 4ft and 7ft, but the cross-onshore wind never lets up. The combined swell energy drops back to moderate levels towards the end, and the period stretches out to 10 seconds for a couple of days on August 30th and 31st, but again, the wind ruins any chance of clean waves.
Given these conditions and the fact this is a point break setup, if someone is determined to get wet, the bigger, stronger swell days late in August look more interesting for a kite surfer than for a paddler. The strength of the wind and the cross-onshore angle would suit a kite much better.
Crouching Lion is an inconsistent spot that needs the right conditions to fire, and this forecast just isn't delivering. It's one of those runs where the blank period feels normal for the area. Don't lose hope though – forecasts can change, and it never stays poor for too long around here.
Rusty.

A general guide to surfing at Crouching Lion can be found by selecting the local surf guide option on the grey menu.

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.
