The Lowdown
Alright, friends, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for a proper surf. We’ve got a whole lot of nothing lined up, and I mean that in the most caring, surf-bro way possible.
The long and short of it is that the waves are tiny, the winds are mostly onshore or cross, and the whole ocean is going to look like a mess of chop and bumps. We’re looking at a serious drought, folks. The first few days are a total write-off, and this flat spell is going to drag on and on. We're talking nearly two weeks of this, so don't be holding your breath for a quick fix.
The only spot we’re even looking at is Octagon House (Octagon). It’s a beginner-friendly, fairly consistent spot that’s exposed to the southeast. But even here, the swell just isn’t showing up. The water temp is sitting at 86°, which is about a degree and a half warmer than usual for this time of year – a little treat, but it’s not going to save the surf.
Let’s walk through it. The run from Saturday the 8th right through to the end of the following week is a total blank. We’re seeing waves under 3ft, with periods mostly in that short, weak 4-6 second range. The energy is pitiful – we’re talking single and double-digit numbers in the combined swell energy, which tells you there’s just nothing out there. The wind is mostly a cross-onshore breeze, making an already poor situation choppy and messy. There’s a moment on Sunday the 16th where the wind goes glassy in the morning, but the swell is still just a pathetic 2ft. It’s clean, but there’s nothing to ride.
Into the second week, things get even smaller. By the 22nd and 23rd, we’re down to a foot or less with next to no energy. It’s a dead ocean. The only thing this setup might be good for is if you’ve got a kite and a wing, because the wind is howling from the southwest at times, but for a paddle surfer, it’s a hard pass.
So, here’s the deal: there are no good surf options in this 16-day window. The spot is fairly consistent, so it tends not to stay this poor for long, but this is a blank run that you’ll want to sit out. Keep the board waxed, but maybe work on your tan instead. Forecasts can change, so I’ll keep an eye on it, but for now, don't get your hopes up.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Octagon House may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
