The Lowdown
Alright, folks, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of small, weak, and messy surf ahead, so don’t be in a hurry to grab your board just yet.
We’re looking at a solid week of nothing but closeout slop and cross-shore chop, with swell heights barely scraping three feet and periods that are all over the shop. The energy in the water is weak, with values like 108 and 171 popping up, and the wind is just not playing ball. It’s going to be frustrating, with a lot of whitewater and not much to actually ride.
The first real sign of life doesn’t show up until Tuesday the 18th. That’s when we see a proper pulse of energy arrive, with the combined energy jumping to 792 and then up to 1273 by the afternoon. The swell is still a bit raw, but it’s something. That bump leads into Wednesday the 19th with chest to head-high waves at 6ft, but the wind is still cross and it’s a bit lumpy. It’s not perfect, but it’s the biggest we’ve seen.
The real standout, the one you’ve been waiting for, is Thursday morning, the 20th of August. The swell drops a touch to 5ft, but the wind goes glassy. Absolutely glassy. Northwest swell with an 11-second period, and the energy is still solid at 560. This is the cleanest, most organized surf we’re going to get in this whole window. The water temp is sitting at 59°, which is about average for this time of year, so don’t expect any surprises there.
Oswald State Park/Short Sands is the spot that’s on the radar. It’s a fairly consistent break, but it’s also exposed to the swell, so it’ll catch anything that comes through. That Thursday morning is the pick, with the glassy conditions making it a proper session. The swell direction is out of the WNW, which is right in its wheelhouse. Get on it if you can.
The rest of the second week fades back into mediocre territory. The swell backs off, the wind comes back onshore, and we’re back to square one. On the whole, if you can only paddle out once, make it Thursday morning. It’s going to be the one to remember.
Rusty out.
