The Lowdown
Alright, this is Rusty. Let's have a look at what we've got for Crouching Lion over the next couple of weeks.
Honestly, the first week and a bit is a write-off. From Sunday the 9th right through to Saturday the 15th of August, it’s a real struggle. We’ve got a persistent cross-onshore wind out of the ENE that’s just messing everything up, and the swell period is short and weak, with combined energy mostly sitting under 500 (moderate). The water temp is a warm 80° and about average for this time of year, but that doesn't help the surf. It’s just poor, choppy conditions day after day. You’d be better off doing something else.
There’s a glimmer of hope on Sunday the 16th of August. The swell bumps up to 10ft to 11ft from the ENE, and the period stretches to a very long 13 seconds, sending the combined energy into the thousands (3061 to 4506). But here’s the thing – it’s blowing onshore from the north and NNE at 15 mph. That much power with that wind? It’s going to be a washing machine. Only for the experts, and even then, it’ll be a battle.
Now, listen up, because Monday the 17th of August is the standout. Finally, the wind swings offshore from the south at 9 mph. It’s clean. The swell drops to a more manageable 6ft from the NE with a 10-second period, and the combined energy is still a solid 667 (moderate to strong). That’s the window. Get out there Monday morning at Crouching Lion. The wind will be gentle and offshore, and it’ll be glassy. Just a heads-up, crowds can be an issue here, so get in early. The afternoon looks a bit more marginal with a cross-offshore breeze.
After that, from Tuesday the 18th of August onwards, we’re back into a long run of poor surf. The ENE wind returns, the swell stays on the short side, and the quality drops right off. There’s a couple of days around the 21st and 22nd of August where the swell is around 6ft to 7ft, but the period is still short and the wind is cross or cross-on, so it’s not worth getting excited about.
Bottom line: the first 8 days are a dud. Your one chance is Monday the 17th of August in the morning. Make it count.
