The Lowdown
Alright, Rusty here, putting it in feet and degrees.
Gotta be honest, the next couple of weeks are looking pretty flat for the Rehoboth Main area. If you’re a beginner, this might be right up your alley, but for anyone wanting a proper wave, we’re looking at a long dry spell. The water's sitting around 75°, which is about average for this time of year, so no surprises there.
The first real chance to paddle out won't come until Thursday, August 20th. That morning, a weak S swell of 3ft slips in, but the period is a short, choppy 4 seconds. The combined swell energy is weak (41). The wind, however, is offshore from the west at 9 mph, making for clean conditions. It’s surfable, but nothing to write home about.
The afternoon of the 20th picks up just a touch. The swell bumps up to 4ft from the south, with a period of 5 seconds, and the combined energy is still very weak (75). The wind goes light offshore from the west at 6 mph, keeping the surface glassy. It’s still only a "surfable" wave, but that afternoon window is the best we’ve got. It’s not a standout, but it’s the only real option.
The morning of Friday, August 21st, could be a session for the longboarders. The swell drops to 2ft, but it’s glassy with a slight air from the NNE. It’s clean, but the wave energy is tiny (47). The afternoon gets a bit of a cross-onshore breeze, which will mess it up a little.
The rest of the 16-day window? You’re looking at days of nothing. From the 6th of August right through to the 20th, it’s a long stretch of tiny, weak swells with poor surf conditions. The wind is mostly cross or cross-offshore, and the wave heights rarely get above 2ft. It’s the kind of flat spell that makes you check the forecast twice. For a beach break like Rehoboth Main, this is pretty normal for a quiet season. It won’t stay poor forever, but right now, it’s a waiting game.
So, if you’re itching to get wet, mark your calendar for the afternoon of Thursday, August 20th. It’s the only real highlight, and it’s a modest one at that. Keep your expectations low, and you might just have a fun little session.
Rusty.

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.
