The Lowdown
Alright, let’s get this straight. I’ve been staring at the charts for the next couple of weeks, and honestly, it’s a tough stretch for anyone chasing waves. The finder is coming up empty for the whole 16-day window, which means there’s no truly good surf on offer. That’s a long, frustrating run, and it’s not just a few days of flatness—it’s a solid blank period.
Looking at the only spot we’ve got on the radar, Octagon House – and it’s a pretty exposed spot that likes a SE swell. The problem is, the swell that’s showing is tiny, mostly from the south and southeast, and it’s just not stacking up. We’re talking surf heights of around 1ft to 3ft, with short, weak periods that never get past 6 seconds for most of the run. That’s not surf, that’s just a ripple. The combined energy barely gets into double digits, with values like 9, 12, or 21 – that’s weak, weak energy. There’s no punch in it at all.
The wind is another story. For the first few days, it’s cross-shore and cross-on, which will chop up whatever tiny, disorganized lumps there are. Tuesday and Wednesday mornings are particularly messy. There’s a chance of a thunderstorm on Tuesday morning, too, which doesn’t help. The wind is mostly light to moderate, but it’s coming from the wrong direction to clean anything up.
We’re looking at a real gap here. The first recommendation doesn’t even exist, so the whole period is a no-go. The conditions stay poor right through the first week, with the surf staying in the 2ft to 3ft range, and the onshore flow constantly messing it up. The only point where the wind might ease is later on, but by then the swell is even smaller.
To be honest, this is a blank run. It’s not a spot that’s known for being consistent, but even so, this is a pretty grim outlook. The water’s warm, around 86°, which is about normal for this time of year, but that’s the only thing that’s going to feel good. The late part of the second week, like the 19th, shows a little glassy morning, but the swell is still just 1ft. It’s not worth getting your gear wet for.
If you’ve got a kiteboard, this might be more interesting, because the small, choppy, cross-onshore mess is going to be more fun for that than for a paddle. Otherwise, save your energy. The forecast can change, but right now, this is a long, dry spell.
