The Lowdown
Alright, Rusty here. Gotta be straight with you—this forecast is a tough one. The whole 16-day window for Octagon House is looking pretty bleak, I'm not gonna sugarcoat it. There’s a massive gap right from the start with nothing worth paddling out for. You're looking at a solid run of poor surf that basically stretches from today, July 15th, all the way through to the end of the period on July 30th, with no standout days or real improvement in sight.
The swell energy is weak across the board, with numbers like 29 (Wednesday morning) or 25 (Wednesday afternoon) showing just how little power there is. We're talking tiny waves, mostly 1 ft to 3 ft, and that's being optimistic. That combined swell energy stays in the low double digits for most of the run, barely cracking 70 on a couple of afternoons. Honestly, the weak, short-period swell (mostly 4 to 7 seconds) is just not gonna deliver anything with a face.
For a beginner-friendly, fairly consistent break like Octagon House, this is a real bummer. The wind is the other problem. It's almost constantly cross-onshore or onshore from the SSE, S, or SSW, which is just going to chop things up. You get a short window of glassy conditions on the morning of Wednesday, July 22nd, with a light WSW breeze, but the swell is only 1 ft and the combined energy is a measly 10 (weak). It's flat.
Even though the swell is small, if you're a beginner, the conditions are so poor and the winds so messy that it's not worth the drive. This setup would honestly be more interesting for a kite surfer than a paddle surfer, given the constant cross-onshore breezes.
The water temp is sitting at 86°, which is a touch warmer than normal for this time of year, but you won't be feeling it on a board that's barely moving.
Honestly, it's one of those stretches where the forecasts can change, but as it stands, there's nothing to recommend. The combined wave energy never gets out of the weak zone, and the direction never lines up right with the optimum SE swell direction for Octagon House to really work. It's a flat spell, plain and simple.
Stay patient, and keep an eye on things. I'm Rusty.
