The Lowdown
Alright, surfers, Rusty here. Let’s be straight with you – the outlook for our little stretch of coast is looking pretty rough.
We’re starting with a major downer. From now through the morning of September 4th, it’s a flat, gutless run of tiny, weak swell and messy conditions. We’re talking nothing but “poor surf conditions” day after day, for nearly two full weeks. That’s a real dry spell.
We’ve got a tiny bit of life trying to creep back in on Friday afternoon, September 4th. The swell will be a weak 3 ft from the South, but with a short, gutless 6 second period. The combined energy is barely moderate at (100). On top of that, we’ve got a moderate cross-shore wind at 16 mph, so it’s going to be choppy and crossed-up. It’s surfable but only just, and it looks more like a kite-surfing setup than a good paddle session.
Then on Saturday morning, September 5th, we get a brief window. The wind will be clean and light at 6 mph from the WSW, making it a cross-offshore breeze. The swell drops to 2 ft from the SSE with a 7 second period, and the combined energy is weak (36). It’ll be clean, but tiny.
Honestly, the only thing that’s kind of promising is the wind on that Saturday morning. But the swell is just too small to get excited about. There is no standout in this 16-day window. It’s a long, flat run. But you know how it goes, it tends not to stay poor for too long, and the long-range models can change.
This is Rusty, signing off.

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.
