The Lowdown
Alright folks, Rusty here. Let's get into it.
Honestly, looking at the next 16 days, it's a grim stretch for Rehoboth Main. We're staring down a long, flat spell with barely a ripple worth paddling for. The water's sitting at a very warm 77°, which is well above average for this time of year, but that's about the only positive.
Right from the start on Monday the 7th, it's a no-go. Waves are tiny at 1 ft from the east with weak energy (25), and a cross-onshore breeze messes things up. Tuesday the 8th is even worse with a 1.0 ft swell. Wednesday the 9th sees a bit of a spike to 3 ft from the south, but the period is a pathetic 4 seconds, meaning close-out slop. The wind goes offshore, so it'll be clean, but there's just no push. Thursday the 10th is the closest we get to surfable, with a 3 ft south swell and offshore wind early morning, but the energy is still weak (49) and the score is a 1. It's a session for a longboard and low expectations.
From there, it's a total write-off. The rest of the first week and all of the second week through to the 22nd offer nothing but small, weak, and messy surf. Most days are scoring a 0. There are a few moments of glassy conditions on Friday the 11th afternoon and again on Thursday the 17th afternoon, but with waves under 2 ft and weak energy, it's not even a bump. We get a little boost on Saturday the 19th with a 3 ft swell from the SSE and clean offshore wind, but the period is only 5 seconds, killing any chance of a decent wave.
Bottom line: don't get your hopes up. This is a classic run of flatness for this area. If you absolutely have to get wet, maybe Thursday the 10th morning is your best, and even then, bring the log and leave the boardshorts. Forecasts can change, but right now, it's a hard pass.
