The Lowdown
Alright folks, Rusty here with the outlook for Rehoboth Main. Let’s be straight with you – this is a tough stretch. We’re looking out over the next 16 days, and the honest truth is there’s no solid surf on offer right now, and it stays that way for a long time.
The water temperature at Rehoboth Main is sitting at 77°F, which is 4°F warmer than average for this time of year. That's notably warm and feels pretty special for an early September paddle, but it’s small consolation when the waves are flat.
We’re going to have a serious gap here. From now until around the 12th of September, it’s pretty much a write-off. The swell is tiny, barely pushing 1ft to 2ft with weak energy readings in the teens and twenties, and the wind is mostly cross or onshore. You’d be better off polishing your board.
The first time things even start to look interesting is on Saturday the 12th of September. We get a jump up to 6ft of swell from the ENE, with a short period of 7 seconds. The combined energy is 268 (moderate), and the wind is cross-off from the NNW at 15-16 mph, which should keep it clean. But the period is short and the quality is marginal. It’s barely a recommendation.
Then into Sunday the 13th and Monday the 14th, we see some 4ft swell hanging around from the east. The energy stays moderate (123 to 204), but again, the wind gets a bit tricky. Sunday afternoon gets a strong cross-off wind at 16 mph, and Monday afternoon turns into a cross-shore mess with a chop. These are ordinary surf days at best.
After the 14th, the swell drops back down again and we’re looking at mostly tiny, weak waves for the rest of the window. A small bump on the 16th with 2ft and clean cross-off wind could give you a shortboard float, but it’s hardly worth the trip.
The real standout? Well, there isn’t one. This is a long, flat spell for Rehoboth Main. If you’re a beginner, the bigger days around the 12th might be too much size to learn on, but the quality is poor, so don't get your hopes up. For the rest of us, it's a wait-and-see game. Forecasts can always change.
Rusty.
