The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Right now, it’s a bit of a slow start. The first few days are pretty messy with cross-onshore winds and choppy conditions, so you’re not missing much if you stay on land. Friday the 7th through Saturday the 8th are blown-out and only offering weak, junky lines. Not worth the paddle.
The first real chance of something clean hits Sunday morning, August 9th. The wind drops to glassy—dead calm—and we’ve got a solid 5ft groundswell out of the ESE, with a 13-second period pushing in. That longer period means more energy and better shape, especially for a point or reef setup. The combined energy is strong at 1420. This window looks excellent for experienced surfers, but it’s not a beginner day. The water temp is sitting at 80°, which is a bit colder than normal for this time of year, so a spring suit might feel good.
If you can get out Tuesday morning, August 11th, the wind swings offshore from the NW at 16 mph and the swell drops to about 3ft from the SSW at 11 seconds. Wave energy is moderate (515), but the clean offshore conditions make it feel better than the numbers suggest. This is a good one for a longboard or a twinny.
After that, the middle of the week goes downhill fast. Wednesday and Thursday on the 12th and 13th are a write-off with strong cross-onshore winds and lumpy, messy surf. There’s a gap of several days with no real standout action.
We get a little bump of interest on Saturday afternoon, August 15th, when a 6ft ESE swell rolls in at 12 seconds, but with light cross-onshore wind, it’s only marginal. Combined energy is solid at 1088, but the quality isn’t there yet.
The standout of the whole outlook, if you can wait, is Wednesday morning, August 19th. Glassy calm, clean, with 4ft of ESE swell at 10 seconds. Wave energy is moderate (360) but the conditions are pristine. This is a rare, clean morning that should offer fun, clean lines. And again on Thursday morning, August 20th—glass again, same size at 4ft from the ESE, with a 9-second period. That’s two mornings in a row of good, clean surf. Mark it on your calendar.
For the rest of the second week, surf stays small and mostly onshore or choppy. Nothing worth getting excited about.
So your best bet is Sunday morning the 9th if you want punch and power, or the glassy mornings of Wednesday the 19th and Thursday the 20th for cleaner, more user-friendly waves.
Stay wet, stay happy.
