The Lowdown
Alright, this is Rusty, and it’s a tough one to call for the next couple of weeks here at Rehoboth Main. Honestly, the outlook is pretty grim for a solid stretch. We’re looking at a long, dry spell with next to nothing on offer for paddle surfing.
Right now, and for the bulk of the next 16 days, we’ve got tiny, weak waves and poor surf conditions. The first sign of anything even resembling a surfable wave doesn’t show up until Wednesday, September 16th. That’s a full week and a half of flat, messy, or choppy conditions. From the 6th through the 15th, it’s all tiny swell, with the combined wave energy barely getting into the double digits. You’ll see a few clean windows, like Tuesday morning the 8th with a light offshore from the northwest, but with only 0.7 ft of swell, there’s just nothing to ride.
The first real flicker of hope comes on the morning of Wednesday, September 16th. We’ve got a clean, offshore wind from the WSW, a 3 ft swell from the east, and the wave comment says “surfable waves but very ordinary conditions.” It’s not a standout, but it’s the only window in the whole run where the wind is truly offshore and the swell is above knee-high. The swell period is a short 5 seconds, so it’ll be a bit weak and crumbly, but for a desperate surfer, it’s your only shot at a weak, clean wave. The water temp is about average for this time of year.
After that, it’s back to messy cross-onshore winds and poor surf. By the weekend of the 19th and 20th, the swell actually picks up—5 ft to 6 ft from the east-northeast—but it’s completely blown out by strong onshore winds. The combined energy jumps to 383 and then 770, which is a lot of water moving, but the wind is just ruining it. The period is short, and the winds are fresh cross-onshore, making it lumpy and messy. For a spot like Rehoboth Main, that setup looks more interesting for a kite surfer than a paddle surfer.
So, to put it bluntly: there’s nothing to get excited about. The only day worth even thinking about is Wednesday, September 16th for a clean but tiny wave. If you’re desperate, that’s your window. Otherwise, the forecast is a bust.
