The Lowdown
Mate, it’s pretty grim out there. The entire 16-day window is a flat spell for Rehoboth Main. The first glimmer of anything surfable doesn’t arrive until Thursday the 17th of September, and even then, it’s just barely. The combined wave energy barely nudges into the weak range (77) on the Thursday morning, with a limp 2ft swell from the ESE. The wind is light and cross-off, keeping it clean, but the swell is weak and short‑period at 9 seconds – not much grunt behind it. That’s the only session that’s even worth a look, and it’s still a long way from being any good.
Before that, from Saturday the 5th right through to Wednesday the 16th, it’s a total write‑off. Swell sits between 0.3ft and 3ft, mostly from the east or south, with energy levels mostly in the low teens to low 40s. Winds are often cross‑shore or onshore, adding chop, and the odd clean spell still leaves you with knee‑high dribble. The water temperature is about average for the time of year, nothing unusual.
The Thursday morning on the 17th is the only real standout, and even then it’s a stretch. It’s clean, light breeze, with a tiny 2ft ESE swell. The period is 9 seconds, so it’s a weak, short‑period groundswell that’ll be inconsistent and soft. If you’re desperate for a paddle, that’s the window, but don’t expect much. After that, the wind picks up and the swell drops back to nothing.
Honestly, this stretch is a bust. The good news is that conditions can flip fast, and a proper swell could turn it around. But for now, leave the boards in the shed.
