The Lowdown
Alright, Rusty here, lookin' at the charts for our local stretch. I gotta be straight with you—this is a tough one to swallow. We've got a long, dry spell ahead before we see anything that even looks like a wave worth paddlin' for.
Right now, and for the rest of this week, it's a write-off. The wind is howling out of the east-northeast, strong and cross-shore, all day, every day. We're seeing a messy, lumpy cross-chop on a swell that's mostly short-period, wind-affected junk. The combined energy is moderate, but it's all wrong for a clean wave. Tuesday the 25th of August through the end of the month, expect nothing but blown-out, sloppy conditions. It's a grind.
We'll see a bit of a shift in the first week of September. The energy stays moderate, but the wind eases up a little. Still, the cross-shore wind keeps things messy. You'll see a few south swells sneaking in with a longer period, but the ESE wind direction is just not right for this spot. The first real glimmer of hope comes on Thursday morning, September 3rd. We get a light offshore breeze from the ESE, maybe 3 mph, with a 4 ft easterly swell and a 13-second period. The combined energy is still moderate (820), but that offshore wind is a game-changer. It's the only morning in this whole outlook where the flags are green. The swell is a bit small, but it should be clean. This is the standout.
After that, it's back to the cross-shore grind. The second week of September sees the swell energy climbing to strong levels, with combined energy readings over 1000 and even reaching 1621 on the 6th. The swell period stretches out to 11-12 seconds, which is proper groundswell. But the wind stays stubbornly out of the east-northeast, cross or cross-on, keeping the surface choppy and lumpy. The waves will have power, but they'll be a battle. Not really a paddle surfer's dream. With that strong wind and sizeable chop, this setup honestly looks more interesting for a kite surfer than a longboarder.
The water temp is sitting at 81°F, which is pretty normal for this time of year, so no need for a thick wetsuit.
In short, the only call I'd make is to set your alarm for Thursday morning, September 3rd. That's your best bet. Otherwise, it's a waiting game. Keep your eyes on the charts, because when it's this poor for this long, it can't stay that way forever.
Rusty, signing off.

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 Middles/Generals 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.
