The Lowdown
G’day, Rusty here. Look, it’s a pretty flat and frustrating stretch of days ahead for the Rehoboth Main area. The swell is tiny and the quality just isn’t there for a proper surf for most of this sixteen-day window. We’ve got a real dry spell on our hands.
Right now, the water’s sitting at a warm 76°, which is a touch warmer than normal for this time of year, but that’s about all the excitement we’ve got.
The first big gap is right from the start. Thursday the 27th through to Monday the 1st of September is a write-off. We’re looking at swell heights around 1ft to 1ft, with combined wave energy barely cracking 30 or 40 (very weak stuff). Winds are mostly cross or onshore, sometimes clean but the waves just aren’t there to ride. The only tiny bright spot in that early stretch is Friday morning the 28th, when it goes glassy with 1ft from the ESE, but that’s still barely a ripple. Not worth paddling out for.
Tuesday the 2nd of September sees a bit of a lift with a 11-second period groundswell pushing in from the SE, and the combined energy hits 43 (still weak). The morning is clean with a light offshore. We’re talking 1ft, so it’s still tiny, but for the dedicated beginner or someone on a foamie, there might be the odd surfable wave. It’s very ordinary, but it’s something.
Wednesday the 3rd of September morning is similar: 1ft from the SE, clean conditions, periods around 9 seconds. Still small, still just for the keen.
Then another lull sets in from the 3rd afternoon right through to the 6th. We get a spike on the 4th with swell hitting 3ft from the east, and combined energy bouncing up to 120 (moderate energy), but the wind is cross-offshore and the quality is poor. On the 6th, the swell bumps to 4ft from the SE, but the period drops to a short 5 seconds, and it’s onshore wind. That’s messy, short-period windswell and not recommended.
The 7th of September has a similar story: 3ft from the SSE, combined energy at 121 (moderate), but onshore wind and a 6-second period. It’s rough.
After that, it fades back to tiny again from the 8th through to the 11th. The 11th of September morning shows a bit of hope with 3ft from the south, a 6-second period, and clean conditions with a light offshore. The combined energy is only 59 (weak), so it’s not powerful, but if you’re desperate, that morning might give you a few soft little waves.
Honestly, the standout—if you can even call it that—is the morning of Tuesday the 2nd of September. It’s the cleanest we get with some groundswell character (11-second period), but the size is tiny at 1ft. The 1ft swell is coming from the SE, which is cross-onshore at Rehoboth Main, but the offshore wind keeps it clean. It’s just very small. The other mention is the morning of the 11th of September, with 3ft and clean wind, but the period is short.
Given the size and conditions, this setup looks far more interesting for kite surfing (if the wind suits) than paddle surfing for most of the period. We’ve got a long stretch of poor surf, but it tends not to stay this flat forever—forecasts can change.
Rusty.

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.
