The Lowdown
Alright, Rusty here again, but in feet and miles for the crew that thinks that way.
This 16-day look at Octagon House is a tough read. From the start on July 25, the waves are tiny with a short period, and the wind is mostly a messy cross-onshore. The water temp is a warm 86°, a bit toastier than normal for the time of year, but it doesn't matter when there's no power.
The first week is a total bust. From Saturday the 25th through the end of July, the swell is barely breaking 2ft, with periods of 4-5 seconds, and the combined swell energy is stuck in the weak teens and twenties. The conditions are all poor.
We see a small bump on August 4th, with the swell reaching 4ft from the S, but the period only gets to 6 seconds and the wind stays cross-onshore. The energy climbs to a moderate level, but it's still a poor setup.
The only real chance comes on the morning of August 6th. The swell is still small at 3ft from the SSE, but the period stretches to 7 seconds, the combined energy hits 79, and we get a clean, cross-offshore breeze from the W. The report says "clean," which is a big deal. It'll be surfable, but still pretty ordinary.
The end of the window, August 9th, shows a spike in energy to a moderate level, but the swell is only 4ft and the wind is messy.
The bottom line: there's no standout. The energy never really fires, and the wind is rarely your friend. If you're itchy for a paddle, that Thursday morning the 6th is your best shot for a clean, waist-high wave on the log. Otherwise, it's a long stretch of flat or ugly surf.
Rusty.
