The Lowdown
Alright, Rusty here again. Let's break down this 16-day stretch for Octagon House, but in feet and miles per hour this time.
To be honest, this forecast is looking like a long, slow grind. We've got a really quiet start. Through the end of August and into the first few days of September, we're looking at barely a ripple. Swell heights are tiny, mostly under 2 feet, coming from the southeast. The wave energy is weak (4 to 25), and the wind is often onshore. The water temp is a warm 87°, just a touch above normal for the season. But for surfing? It's a total blank.
We do see a bit of a pulse around the 8th of September, a Tuesday. The swell bumps up to about 5 to 6 feet from the south-southeast, with the wave energy hitting a moderate 309. That's the biggest swell of the whole outlook. The problem is the period is short, around 7 seconds, and the wind is blowing directly onshore from the southeast at 9 to 12 mph. That's going to make for a real sloppy, blown-out mess. For the experts, it might be something, but the conditions are poor.
The one small window that might be worth checking out is on the morning of Friday, September 11th. We've got a cleaner 4 to 4 foot southeast swell with a light, 6 mph cross-shore breeze from the southwest. The energy is moderate (80), and that wind should clean it up a bit. It's not going to be world-class, but it's probably the most surfable session in the entire run. The afternoon gets choppy again as the wind strengthens.
So, the bottom line is: the first week is a flat, windy wasteland. The second week brings a short-period, onshore swell that's not great, but the morning of the 11th is your best bet for a few clean-ish waves. It's a lean outlook, for sure.
Rusty.
