The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for Rehoboth Main over the next couple of weeks. I’ve got to be straight with you – it’s a lean stretch. The forecast is pretty much a flat spell, so we’re looking at a long gap before anything even sniffs like a wave.

Right now, and for the entire 16-day window, the options are bare. The first few days are a write-off. From Tuesday, 11 August, right through the weekend and into the following week, the swell is tiny, barely scraping 1 ft to 2 ft, and the period is short – mostly 4 to 8 seconds. That’s windswill, not surf. The energy is weak, with combined readings in the single digits and low teens (9, 19, 6, 7, 12, 8, 15, 16, 22, 16, 9, 37, 44, 28, 36, 27, 52, 85, 34, 32, 13, 13, 36, 21, 35, 22, 20, 36, 30, 32, 17, 30). Nothing to get excited about. The water temperature is sitting at 78°F, which is a touch warmer than normal for this time of year, so at least it’s pleasant for a paddle.

The first real chance of anything comes around the week of 19 August. Even then, it’s marginal. On Wednesday, 19 August, we see a bump to 3 ft from the S, but with a period of only 4 seconds and a moderate cross-onshore breeze, it’s going to be choppy and messy. That’s a kite-surfing setup, not a paddle-surfing one. The energy ticks up to 85, but it’s still weak.

The best on offer, and I’m stretching here, lands on Monday, 24 August. We get a clean, cross-off wind from the NW at 12 mph, with a 1 ft swell from the SE at a period of 12 seconds. That long period groundswell will at least give some shape, but at 1 ft, it’s barely a ripple. The energy is a paltry 36. The wind is good – clean – but there’s simply not enough water moving. For a break like Rehoboth Main, which is exposed and always crowded, this is a tough sell. The wind direction (W offshore) and the optimum swell from the E don’t match up perfectly, and the swell is coming from the SSE, which is off-angle.

Honestly, for the whole 16 days, there’s nothing that qualifies as a standout. The surf is poor, the conditions are poor, and the scores are all zeros. We’ve got a solid 11-day gap from the start with no recommendations, and even the second week doesn’t deliver. Keep the board in the car just in case a rogue set rolls through, but don’t hold your breath. Forecasts can change, but right now, it’s looking like a long flat spell.

Rusty.
