The Lowdown
Alright folks, Rusty here. Let's have a look at what’s on offer at Octagon House.
To be straight with you, the outlook for the next 16 days is pretty grim. We’ve got a long gap of flatness with no real surf to get excited about. The pattern is stubbornly small and onshore for most of the stretch.
Looking at the water temp, it’s sitting at 87°F with an anomaly of 3°F warmer than usual, so it’s a touch warmer than normal for this time of year.
The first real chance for a paddle comes on the morning of Thursday, 3rd September. We’re looking at a tiny 2ft swell from the SE, but the real talking point is the glassy conditions. That’s the best wind we’ll see in the whole period, making it clean and inviting despite the flatness. The swell energy is pretty weak at (12). It’s a rare moment of calm for beginners to get a feel for it.
Friday morning, 4th September offers another window with glassy conditions and a small 1ft SE swell. Again, it’s not going to blow your hat off, but the clean surface (10 energy) makes it a worthwhile session for a longboard or a foiler. These two mornings are the only true standouts in the whole run.
After that, we slip back into a pattern of weak, short-period windswell. From the 5th through to the 12th of September, it’s mostly cross-onshore or onshore winds, with wave heights barely scraping 3ft. It’s messy, choppy, and not worth getting up early for. The combined swell energy stays in the weak range, peaking at just (59). For a beach setup like this, with poor surf quality and fresh winds, this stretch looks more interesting for kite surfing than paddle surfing. The bumpy, lumpy conditions won’t offer much for a surfer.
Saturday morning, 12th September is our last look – a tiny 0.7ft SSE swell with light cross-shore wind, but the energy is as low as (8). Likely a flat session.
Honestly, if you’re hoping for a proper wave, this forecast is a bust. We get two brief, clean windows on the 3rd and 4th of September, and then a whole lot of nothing. Hang in there – forecasts can change.
Rusty.
