The Lowdown
Alright, Rusty here. Let’s cut to the chase. It’s a rough stretch.
We’re looking at a long, flat spell. From now, right through the end of July and into the first few days of August, it’s a total bust. The swell is tiny, the wind is ugly, and every report is calling it “poor surf conditions.” It’s a solid run of cross-shore chop and onshore mess. The wind is the only thing with any real power, so if you’ve got a kite, this is more your scene. The combined wave energy is weak, barely making it past double digits (16 on Monday morning, peaking at 72 by Saturday afternoon, but with no quality to show for it).
Finally, a tiny window pops up on Monday, August 3rd. The morning session at Octagon House is the only thing worth getting out of bed for. The wind goes glassy—dead flat, clean as can be—and we’ve got a weak 0.8m swell from the south. The combined energy is still low (57), but for a few hours, the surface will be perfect. The water is warm, about 85.8°, which is a touch above normal for this time of year. The catch is, it’s a beginner-friendly spot, it’s fairly consistent, but it’s exposed to a southerly swell, and the period is short (6 seconds), so the waves won’t have much push. Still, it’s the only clean, surfable window in the entire outlook. Expect a few other folks out.
After that, it’s back to the grind. Tuesday the 4th through the 11th of August is a dead zone. The swell stays under 3.0 ft, the wind is all cross-on or onshore, and the conditions are consistently poor. There’s a clean morning on Thursday, August 6th with a light cross-offshore breeze, but the swell is only 2.0 ft, and the energy is pathetic (21). It’s a tease.
So, the bottom line? One standout, and it’s that Monday morning, August 3rd, at Octagon House. If you’re jonesing for a paddle, that’s your only shot. Otherwise, the next two weeks are a wash. Forecasts can change, but right now, it’s a long, quiet wait.
