The Lowdown

Alright folks, Rusty here. Let’s get straight into it for Rehoboth Main. I’ve looked over the next couple of weeks, and I’m not gonna lie to you – it’s a tough stretch. We’re looking at a real dry spell for most of the outlook, with very little on offer that’s going to get a surfer out of bed.

The first week and a half is pretty much a write-off. From now through to the middle of next week, the waves are tiny, the swell direction is all over the place, and the periods are short. We’re talking knee-high slop at best, with a lot of cross-off or even onshore wind. The water temperature is sitting around 77°, which is a solid 4° warmer than normal for this time of year, so it’s a warm bath, but there’s no energy to ride. The combined swell energy barely cracks double digits, just 26 on the Friday morning, and it doesn’t get much better. It’s a frustrating start.

We finally get a bit of a pulse around Tuesday, September 15th. The morning shows a modest 4 ft swell from the south, with a period of 6 seconds, and that combined energy jumps to 184. It’s still not a classic groundswell, but the big news is the wind. It’s glassy. Dead flat, no wind. That’s the only window where you might get a clean wave. The swell is under 5 ft, so it’s manageable for most, but it’s a short period, so it’ll be a bit crumbly and inconsistent. That’s your best bet for the whole 16 days, but it’s hardly a standout.

After that, it drops back into the doldrums. The following Friday morning, September 18th, brings a bit of a whisper with a 3 ft swell from the east-northeast and a gentle offshore breeze, giving a combined energy of 92. It’s clean, but the waves are small. For a spot that’s exposed and sees crowds always, this is a tough run. Honestly, for most of this period, the setup looks more interesting for a kite than a paddle. The beach break won’t be holding much.

So, to sum it up: keep your expectations low. The best you’ll see is a glassy morning on the 15th, but it’s not the kind of swell that lights up the point. It’s one of those quiet spells for the area. Forecasts can change, but right now, there’s not much to chase.

Rusty.
