The Lowdown
Alright, Rusty here again, but in feet and miles for the old-school crew. Let me tell you, it’s a dead zone out there for Rehoboth Main over the next 16 days. Don’t even bother.
From start to finish, you're looking at swell that barely scrapes 2 feet at best. That’s on Wednesday the 2nd of September, when it hits 0.5m – call it around 2 feet – with a period of 11 seconds. The combined energy is 63, which is still weak juice. And guess what? The wave comment still says "poor surf conditions." So that’s your highlight. A weak, poor-condition bump.
Every single day before and after is the same story: tiny waves, poor surf, and not a single standout. The water temp is average for the season, nothing wild. On Sunday the 7th of September, the wind turns offshore from the west at around 9 mph, giving you clean, glassy looks, but the swell is barely 0.7 feet. Period of 7 seconds. Energy of just 8. That’s lake chop, not surf.
The flat spell is relentless. There’s a moment on the 10th with offshore wind again, but it's the same story – knee-high dribble. Nothing changes.
It’s a beginner break, and it’s always packed when there’s anything rideable, but there’s nothing for anyone. Not even the kites would bother. The whole 16 days is a bust. Forecasts can flip, but right now, Rehoboth Main is giving you nothing.
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.
