The Lowdown
Alright, Rusty here, and I’m calling it like it is: this stretch at Rehoboth Main is a total dud for the next 16 days. Don’t waste your wax.
The whole outlook is flat and weak. Starting Tuesday the 21st of July, tiny swell with poor wind. On Wednesday the 22nd, we get a glimmer with 0.9m SSE swell and offshore winds, but the energy is weak (86) and the waves are just "surfable but very ordinary." Not worth getting wet for. The same story on the 28th—a little cross-offshore wind, but still tiny.
The only real standout is the morning of Thursday the 30th. We get a clean 3ft south swell with a fresh offshore breeze from the west. The energy is moderate (170), but the period is short at 8 seconds and the quality is still "poor surf conditions." It’s the best we’ve got, but it’s small and weak. Fine for a beginner on a foamie, but nothing to get excited about.
Water temp is about average for the season.
After that, it’s flat and choppy right into August. We get a glassy morning on the 4th and 5th, but with swell heights of 1ft and 1.0ft, it’s a bathtub. Energy numbers are in the 20s—weak.
No surf to speak of. If you’re a kite surfer, the wind might be worth a look, but for a paddle surfer, this is a bust. Forecasts can change, but right now, it’s a hard pass.
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.
