The Lowdown
Right, Rusty here. Let’s be straight with you — this is a rough one for the Rehoboth area. The whole 16-day window is pretty much a bust for anything worth paddling out for. I’m not seeing a single decent wave in the cards. From now through to the 14th of August, it’s all tiny, weak, and mostly messy.
We’re talking about Rehoboth Main, and the water temp is sitting at 75° — that’s pretty normal for this time of year, no surprise there.
The swell never gets going. Most of the time we’re looking at 1 ft to 2 ft of slop out of the southeast, with periods hanging around 3 to 8 seconds. That’s all short-period, junky windswell with no punch. The combined energy readings are all weak, plain and simple. Nothing to get excited about.
The wind is a mess too. Sure, there are a few glassy moments — like the morning of the 8th of August and the afternoon of the 11th — but with barely any swell, it doesn’t matter. The water is flat or close to it. The rest of the time it’s cross-off, cross-on, or straight onshore, and we’ve got some stormy days with risk of thunderstorms mixed in, especially around the 3rd and 4th.
Because the swell never reaches over 5 ft, there’s no danger for beginners, but there’s also nothing to ride. The whole stretch is a blank run. Honestly, for a place like Rehoboth, this kind of dead spell is more normal than not in summer. It tends not to stay this poor forever, but this forecast is a write-off for paddle surfing. If you’ve got a kite, you might find a window, but for a surfboard, leave it at home.
Rusty.

A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Rehoboth Main) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rehoboth Main may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
