The Lowdown
Alright, let’s call it like it is – the next sixteen days at Rehoboth Main are looking pretty flat. I’ve gone through the whole run and there’s hardly a wave to get excited about. The swell stays tiny, mostly under 3 feet, and the energy is weak. The first decent chance doesn’t even show up until the middle of the first week, and even then, it’s a long shot.
We kick off Tuesday the 28th with a bit of a nothing burger. A south swell of 1 ft and a short 8-second period, cross-shore wind, and the water temp is sitting at 75°, which is pretty normal for this time of year. Combined energy is only 27 – that’s weak. The next few days are more of the same: Wednesday the 29th shows a little 2 ft to 3 ft swell from the southeast, but the wind is cross-offshore and the waves are just too small to do anything with. The energy creeps up to 68 on Wednesday afternoon, but it’s still feeble.
Thursday the 30th and Friday the 31st are flat as a pancake – 1 ft to 2 ft, with clean conditions but absolutely no push. The weekend into early August is a write-off. Winds turn onshore and choppy, swell barely registers, and the energy drops into the teens. Monday the 3rd sees a bit of a bump in combined energy to 106 (moderate), but the swell is only 3 ft, onshore, and messy. That’s about as good as it gets, and it’s not saying much.
From Tuesday the 4th onward, it’s a long stretch of tiny, weak surf. There are a few glassy mornings on the 6th, 7th, and 8th, but the swell is 1 ft to 2 ft – barely a ripple. The energy is in the 15 to 37 range. The second week is a total drought. By the 12th of August, we get a little puff of offshore wind, but the swell is 0.3 ft to 1 ft. It’s a clean, flat ocean.
The standout? Honestly, there isn’t one. The best you’ll find is the morning of Monday the 3rd of August – that 3 ft swell from the southeast with 106 energy, but it’s cross-onshore and the period is short at 7 seconds. It’s not worth paddling out for. If you’re desperate, the glassy mornings on the 6th, 7th, and 8th offer the cleanest conditions, but there’s no wave to ride.
This is a blank run. Rehoboth Main is a beginner-friendly beach break, but when it’s this flat, even the longboards are staying home. Forecasts can change, so keep an eye on it, but right now, I’d leave the board in the car.
