The Lowdown
Alright, let’s get this straight. The charts are showing a long, flat spell ahead, and I’m not going to sugar-coat it. We’re looking at a good stretch of days where the surf just isn’t going to show up. From the get-go, the swell is tiny and disorganized. The water is sitting at 64°, which is a touch warmer than normal for this time of year, so that’s something at least.
The first real pulse of energy doesn’t arrive until around the 12th of August, and even then, it’s weak. The wind is mostly cross-off or straight offshore, which would be fine if there was any swell to work with. By the morning of the 13th, the energy picks up a bit, with the combined energy hitting 227, but the wave height is only around 3ft. It’s clean, but it’s just not enough to get excited about. The swell is coming from the WSW with a period of 10 seconds, so it has a bit of push, but it’s still pretty marginal.
The middle of the week, around the 14th and 15th, is still poor. The swell drops back off, and we’re back to ankle-biters. The 16th has a little bump back to 3ft, but it’s short-period windswell and inconsistent. Nothing worth getting out of bed for.
Then, things get interesting around the 19th of August. That morning, the swell jumps to 6ft, with the combined energy hitting 322. The wind is fresh offshore from the NW, so it’ll be clean and lined up. This is the standout of the whole window. It’s a bit short-period at 7 seconds, so it won’t have the power of a groundswell, but for a beach break, it should be fun. The afternoon keeps the size, with the energy even higher at 352. This is the one to chase.
The 20th is still surfable, with 4ft in the morning and a moderate cross-off breeze, but it’s already starting to fade. After that, the swell backs off again, and the last few days of the window are small and weak again. A long period swell shows up on the 23rd with a 14-second period, but it’s tiny at 1ft, so it’s not going to do anything.
So, here’s the deal. Most of this 16-day stretch is a bust. The only real standout is the morning of Wednesday, the 19th of August. That’s the one to mark on the calendar. Everything else is a lot of paddling for not much return. Keep the expectations low, and you won’t be disappointed.
