The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next 16 days at Rehoboth Main are looking pretty grim. We’re staring down a long stretch where the surf is just not cooperating. The first solid recommendation doesn’t pop up until the 15th of September, so we’re talking about a gap of over a week with nothing worth paddling out for.
The little bumps we do see are tiny. On Friday the 4th, we’ve got a 1 ft swell from the southeast with a weak combined energy of just 21, and a cross-off wind from the northwest at 16 mph. The water is a balmy 77°F, which is a whopping 4°F warmer than usual for this time of year – that’s a real standout, but it’s not enough to save the surf. The waves are just too small and weak to ride.
The pattern stays flat and messy. Saturday the 5th sees a 0.7 ft swell with a cross-on wind, and Sunday the 6th has onshore winds and rain. Even the few cleaner moments, like Tuesday the 8th with a light offshore wind, only offer a 1.0 ft swell. The combined energy never gets above 55 (a weak total) until well into the second week. Honestly, it’s a write-off for paddle surfing for days.
Now, finally, on Tuesday the 15th of September, we get a little flicker of hope. The afternoon session shows a 3 ft swell from the ENE, with a period of 6 seconds and a combined energy of 92. The wind goes glassy, which is a major positive – it’ll be clean. The waves are surfable, but it’s very ordinary. The swell is short-period, so it won’t have much push, and the size is only for beginners. It’s the best we’ve got, but it’s not a standout by any means.
The rest of the week after that is more of the same: small, weak, and mostly cross or cross-off winds. The 18th of September sees a 0.7 ft swell with a 12-second period, which is a long period groundswell, but it’s simply too small to do anything with, and the combined energy is a pathetic 27. The wind is clean, but you’d be bobbing around for nothing.
So, the bottom line: this is a tough stretch. The only session worth a look is late on the 15th of September during that glassy window, but keep your expectations low. The rest of the 16 days, you’re better off doing something else.
Rusty.
