The Lowdown
Alright, let’s get this out there. The next couple of weeks are looking pretty flat and weak for us at Rehoboth Main. I’ve got to be straight with you—this isn’t a period to be planning your life around. We’ve got a lot of small, weak swell and the wind is mostly going to be messing with what little we have. It’s going to be a lot of staring at the ocean, waiting.
Water temp is sitting right around 75° and that’s pretty normal for this time of year, so no surprises there. Just your standard warm summer water.
We start out with a couple of days of really tiny, poor surf. Through Friday and Saturday, we’re looking at maybe 1ft of swell from the southeast with a short, weak period. There’s a light breeze in the mix, but the shape is just poor. The energy is in the low 20s, which is just weak. Not worth getting wet for unless you’re really desperate.
Over the weekend, the swell gets a little bump but it’s still nothing to write home about. Sunday sees a bit more swell from the southeast, but the wind is going to be cross-onshore, making it choppy. Then, Monday on the 3rd, we get a bit of a pulse. The swell picks up to about 4ft to 5ft from the south-southeast, and the combined energy jumps into the 170 to 237 range, which is a moderate bump. The wind is cross-offshore from the southwest, so it’s clean. The problem is, it’s still got that short-period energy, around 7 to 8 seconds, so it’s going to be a bit crumbly and soft. The reports still call it “poor surf conditions”. This is probably the most surf we see in this stretch, but it’s not going to be great.
Tuesday the 4th, we get a little glassy moment in the morning with the wind dropping to nothing. The swell is down to 2ft and it’s the only time the forecast says it’s “surfable waves but very ordinary conditions.” So, that’s your one-star window. If you’re a beginner and just want to bob around, that’s your chance. But don’t expect much.
After that, it’s more of the same. We’ve got a run of days from the 5th through the 9th where we hover around 3ft to 3ft, mostly from the south and southeast, but the wind keeps changing, and the overall energy is weak to moderate. There’s another small bump on the 8th, with energy around 181 in the morning, but the swell is short period, and the surf quality is still called poor. The best of this stretch is on the 8th in the morning with a clean 3ft from the south-southeast and a light southwest wind, but it’s still not a standout. It’s just the best of a bad bunch.
From the 10th onward, the surf drops off again. We’re looking at 1ft to 3ft with energy dropping into the teens and twenties. There’s a lot of days with no real push. The wind is all over the place but the waves are just too small to do anything. The 12th has a glassy moment, but the swell is a tiny 1ft. The 15th, which is more than a week out, shows a bit of a pulse from the south with a 2ft wave, but the wind is onshore and the period is a weak 4 seconds. It’s not worth holding out for.
All in all, there are no real standouts in this 16-day window. The energy is mostly weak, and the one moderate push we get on the 3rd is let down by the short period. This is just one of those flat summer stretches. Stay patient, keep the board waxed, and check back. Forecasts change. I’m Rusty, and I’ll see you down the beach.

Information about the Rehoboth Main Surf forecast
The above surf forecast table for Rehoboth Main provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu. Our Rehoboth Main surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. 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.
Rehoboth Main is 41 km (25 miles) from Ocean City. If you plan a vacation in Delaware, look for hotels and other accommodation in Ocean City. Ocean City has rooms for a wide range of budgets as well as car hire and transport links.
