The Lowdown
Alright, grab a coffee, let’s have a look at the next couple of weeks. I’m not gonna lie to you, it’s flat. Proper flat. We’re talking about a stretch that starts with nothing and just keeps going. There’s a big gap of silence here, so don’t be rushing to get your wetsuit on just yet.
We kick things off on Thursday, the 3rd of September, at Rehoboth Main. It’s a beginner spot, exposed to the east, and you’ll see a tiny 1ft swell from the southeast, with a period of 9 seconds. The combined energy is weak, sitting at just 39. The water is a warm 77°, which is much warmer than normal for this time of year – over 4 degrees warmer, so that’s a nice surprise. Thursday morning has a WSW offshore breeze, so it’s clean, but there’s just no power. By the afternoon, the wind goes glassy, which is a treat, but the waves are still tiny and ordinary. Friday morning sees a cross-offshore wind from the NW at 9 mph, but the swell drops further to 1ft and the period shortens to 8 seconds; energy plummets to 18. Honestly, it’s poor. The whole weekend is a write-off. Saturday has a 1ft swell with a terrible 6-second period, and by Sunday, we get a bit of a bump up to 3ft, but it’s from the ENE with a 4-second period – that’s just wind chop, and the wind is cross-onshore, making it choppy and messy.
Monday the 7th offers a tiny glimmer. The swell is 2ft from the east with a period of 11 seconds, which is a long period, but the energy is still weak at 83. Monday afternoon the wind goes glassy again, so it’s clean, but it’s still just small and ordinary. After that, it’s back to tiny, weak swells. The whole first week is a bust. The second week stays the same story. From the 8th through to the 18th of September, we see nothing but 0.7ft to 2ft swells, with periods mostly between 6 and 10 seconds, and energy levels that never break 100. The wind is often offshore or cross-offshore, which keeps the surface clean, but there’s just no wave height to work with. Even on the 18th, as the wind goes offshore again, the swell is only 2ft from the east with a 7-second period. It’s clean, but you’d be fighting for a dribble.
So, here’s the bottom line: there are no standouts in this 16-day window. The whole period is a flat spell. The best you can hope for is a glassy, clean day on Monday the 7th with a tiny 2ft swell, but that’s not a surf, that’s a paddle. For an area that is fairly consistent, this is a proper dry spell. Forecasts can change, but right now, the only thing on offer is a clean, flat ocean. Hang up the board for a bit.

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.
