The Lowdown
Alright, surf crew, Rusty here with a look at what Rehoboth Main has on the cards. Honestly, it’s a tough stretch ahead. The pattern is pretty bleak for most of the next two weeks, with only tiny windows of hope.
The entire first week is basically a write-off. From this Saturday the 12th through to the morning of Sunday the 20th, there’s nothing worth paddling out for. The swell is tiny, the periods are short, and the wind is all over the place. You’re looking at days and days of flat, choppy mush. It's a real bummer.
Things finally, *finally*, show a glimmer of life on the morning of Sunday the 20th. It’s not a classic by any means, but the wind goes glassy, 0 mph, and we get a tiny 1.0 ft wave from the ESE with a long period of 11 seconds. The combined energy is weak (45), but for the first time in over a week, it will be clean. It’s just very small and ordinary.
After that, we get hit. The 21st of September sees a big jump in swell – 7 ft from the ENE on Monday morning, with a combined energy of 542. But the wind is howling onshore at 25 mph, making it a total mess. That swell sticks around through the 22nd, but with strong onshores. The water temperature is a notable 76°F on Saturday the 12th, which is much warmer than normal for the time of year.
There’s another spike on the 23rd of September, Wednesday morning, with a 6 ft swell from the ESE, an 828 combined energy, and a period of 9 seconds. The wind is a cross-shore breeze, which is better. It’s labeled as marginal, and with that kind of energy, the setup looks more interesting for kite surfing than paddle surfing. For a surfer, it’s just messy and blown out.
The rest of the forecast into the 27th drops back down in size but stays windy and choppy. There are no standouts. If you have to, that glassy Sunday the 20th is the only clean chance, but bring a longboard.
