The Lowdown
Right, let's talk about Octagon House (exposed to the SE). Honestly, what a bummer. Over the next couple of weeks, I'm just not seeing any surf worth paddling out for. For the first ten days or so, it's all tiny, weak windswell with periods barely reaching 5 or 6 seconds, and the wind is blowing cross-shore or onshore nearly all the time, which just ruins what little bump there is. Every single report says "poor surf conditions." There's nothing to get excited about.
The water is sitting at about 87°, which is a touch warmer than average for this time of year, but that doesn't help the waves. The energy readings are all pitiful, like on August 5th with only 15 (15) – that's just nothing. You'd be bobbing around in a choppy, messy lake.
And as we push into the second week, it doesn't get any better. Swell tops out at maybe 3 feet, but it's still coming from the southeast with a short, weak period, and that nagging cross-shore wind just won't let up. For the entire 16-day window, there's not a single day that stands out, not a single decent window. The setup looks more interesting for kite surfing with that steady side-breeze than it does for a surfer. If you're a beginner who's happy to get wet on something tiny and crummy, go for it, but for anyone else, it's a hard pass. This kind of flat spell can happen around here. Better luck next time.
