The Lowdown

Alright folks, Rusty here. Let's take a look at what's cooking for Rehoboth Main over the next couple of weeks. I gotta be straight with you—it’s a pretty quiet run for the most part. We’ve got a long stretch of small, weak waves, and it’s not really until three weeks from now that things might wake up. For the next week and a half, most of these days are just poor surf conditions with tiny swells.

The water temp is sitting at a warm 79°, and it's running a touch warmer than normal for this time of year, so you won’t need a thick suit.

Right now, on Wednesday the 12th, we’re looking at a tiny 0.7ft southerly swell with a weak energy reading (7). Thursday the 13th sees a slight bump to 1ft from the south, but the period is a short 4 seconds, so the wave energy is still very low (10). Friday and Saturday stay in the same hopeless range, with Sunday afternoon offering the first glimpse of something rideable—a 3ft southerly swell with 4-second period (42 energy) and clean conditions thanks to a cross-offshore wind. But honestly, that’s still a pretty marginal wave.

The real standout in this whole 16-day window is Friday morning, August 21st. We’ve got a 5ft south swell rolling in with a 7-second period, and the combined energy jumps up to 250. That’s moderate energy, and with a clean cross-offshore wind from the NNW, it’s going to be the cleanest, most surfable morning we’ve seen in a while. The wave direction is S, but the optimum swell here is from the E, so it won’t be perfect, but it’s the best of a rough patch by a long shot.

The rest of the second week is a washout until we hit the morning of Tuesday, August 26th. That’s when a bigger swell from the ESE arrives, showing a solid 5ft with a period of 7 seconds and a strong energy reading of 462. The problem is the wind is cross-onshore from the NE, so it’s going to be choppy and messy. This is the kind of setup that might actually be more interesting for kite surfing than paddle surfing, given the size and the lumpy conditions.

So, to sum it up: there’s no surf worth paddling for until Friday morning, August 21st. That’s your one true standout—clean, moderate energy, and a fun-sized wave. Everything else is small, weak, or blown out. Keep an eye on that late August window though; the swell is there, we just need the wind to cooperate.

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.
