The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks. I’ll be straight with you – it’s a tough one.
We’re looking at a real dry spell for the entire 16-day window. The first real surf to speak of won’t show up until after the first week, and even then it’s nothing to write home about. There’s a long, quiet stretch from now all the way through to mid-August, with nothing but tiny, weak waves and poor conditions. The only break on the cards here is Rehoboth Main.
For the most part, the swell is tiny, often below 1 ft, and the period is short, giving the waves no push or shape. The water is a touch warmer than normal right now, coming in at 78°F, which is a bit unusual for this time of year.
The first day that shows any kind of pulse is Sunday the 16th of August afternoon. We get a bump up to 4 ft from the south, but it’s a short period of 5 seconds and the wind is a fresh cross-shore breeze at 19 mph, making it lumpy. The combined energy is weak (54). It’s still rated as poor surf conditions. This is not the day to paddle out.
Things get a little more interesting around Tuesday the 18th of August. The swell stays small at 1 ft, but the period jumps to 15 seconds, which is a very long groundswell coming from the southeast. This creates some moderate wave energy (121) on the afternoon. The problem is the wind is a fresh cross-onshore breeze at 19 mph, making it lumpy. A long period swell like this at a beach break tends to break too straight, so don’t expect much shape. The setup looks more interesting for a kite surfer than a paddle surfer.
Wednesday the 19th of August keeps that same long-period groundswell (12 seconds) from the southeast, with 2 ft swell and moderate energy (120). The wind is onshore or cross-onshore at 12-16 mph, so it’s not clean. It’s still a tough call.
The rest of the outlook through to the 25th of August just fades back into small, weak, and choppy conditions. There’s no standout swell, no clean offshore winds, and no real quality to chase. Honestly, I’d leave the board in the car and check the forecast again in a few days. It’s a blank run, and for this area, that’s pretty normal. The forecasts can change, but right now, there’s nothing to get excited about.
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.
