The Lowdown
Alright, Rusty here.
Honestly, the next 16 days are a real struggle for a wave. Most of the time, we’re looking at tiny, weak surf with poor conditions. There’s a big gap of nothing really worth paddling out for from now until about the 7th of September. From the 7th to the 15th, it’s still mostly ankle-to-knee high slop with very ordinary conditions. The real bright spot—the only one worth getting excited about—lands on Thursday, September 17th.
The standout is Rehoboth Main. On the morning of the 17th, we finally get some proper push. Swell builds to 6 ft out of the E, with light offshore wind from the W. That’s clean, lined-up surf. The combined energy hits a moderate 217, so there’s some decent grunt behind it. It’s a groundswell but short period at 6 seconds, so it’ll be a bit crumbly and sectiony. Still, this is a beginner break, and 6 ft is pushing it for less experienced crew—it might be a bit much. For those who can handle it, this is the only window with genuine shape.
Before that, the 15th and 16th show tiny bump at 3 ft with clean conditions, but it’s really just knee-high dribble. Nothing to rush for.
Water temp is about average for this time of year, nothing to write home about.
So, mark your calendar for Thursday the 17th. That’s your session. Everything else is a write-off.
