The Lowdown
Alright, let me tell ya, it's Rusty here, and I've got the scoop on Rehoboth Main. Gotta be straight with you – this run ain't looking like much. We've got a long, quiet stretch ahead, so don't go getting your hopes up just yet.
For the next week or so, it's pretty flat and messy. We're looking at small, weak waves pushing in from the east and southeast, but the wind is never your friend. Most of the time it's blowing onshore or cross-shore, just chopping everything up. You'll see wave energy readings in the low double digits – like 23, 33, 44 (weak energy) – just tiny, weak slop. There's a brief moment on Sunday the 13th where the wind drops out – Sunday afternoon goes glassy with a little 1ft SSE swell, but it's barely a ripple. The morning before that is clean but still tiny at 2ft. That’s really the only window for a longboard or a foiler, but it's not exactly a standout.
Now, things start to change a bit around the 18th of September. The swell energy starts to pick up – we see an afternoon on the 18th with 4ft from the ENE and a combined energy reading of 123 (moderate wave energy), but the wind is still a problem, blowing cross-shore and messy. Then on Saturday the 19th, we get a little glimpse of something better. The morning shows 3ft from the east with a light offshore wind from the northwest, which cleans it right up. The wave energy jumps to 149 (moderate wave energy). It's still not pumping, and the scores are low, but that offshore breeze will make it the cleanest wave of the whole outlook.
But don't get too excited. After that, it turns back into a windy mess. The end of the third week and into the fourth sees some bigger numbers on the swell – like 4ft to 4ft and energy readings hitting 301 (strong wave energy) on the 23rd – but the wind is howling. We're talking near gale-force onshores, blowing the ocean flat sideways. That's not surf, that's a washing machine.
Honestly, if it weren't for that Saturday morning on the 19th, I'd say take the whole two weeks off. That's the only one that has any appeal, with clean conditions and a little bit of east swell. The rest of the time, the wind just never lines up right. It’s a tough run for a spot that's exposed to the east – we just need the wind to give us a break.
Stay patient, and check back next week.
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.
