The Lowdown
Let’s talk Rehoboth Main. The water’s sitting at about 75°, so right where you’d expect for the season. But the surf situation is a bummer.
We start off with a clear Sunday afternoon, but it’s a tiny 2ft SSE swell with a 4-second period, cross-on wind at 15 mph, and a combined energy of just 20. It’s poor, plain and simple.
Monday morning and afternoon see a bit of life: a 4ft SSE swell, period up to 8 seconds, and the combined energy jumps to 192 and 191. The wind is cross-off from the SSW at 15 mph, so the surface looks clean. The guidance still calls it poor, but for a beginner-friendly break, those chest-to-head-high waves with clean conditions are about the only thing worth looking at. Might be a bit much for total beginners, though.
Then it all falls apart. From Tuesday afternoon all the way through the end of the 16 days, it’s tiny stuff, mostly 2ft to 3ft, with combined energy dropping into the teens, 20s, or low 30s. Winds shift around, but the waves are just too small and weak. There’s a brief glimpse on Saturday, August 9th, with a 3ft S swell, 6-second period, and a light offshore breeze, but it’s still only a 1 out of 10 and described as surfable but very ordinary.
Your best bet is Monday morning and afternoon. After that, it’s a long stretch of barely rideable stuff, with the last few days dropping to less than a foot. It’s going to be a quiet couple of weeks.

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.
