The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for our stretch of coast.
To be honest, the next couple of weeks are looking pretty quiet. We've got a long stretch of small, weak surf with no real punch. The energy just isn't there. The first real chance of anything surfable pops up on Sunday the 23rd, but it's nothing to write home about. The water's sitting at a toasty 76°, which is a touch warmer than normal for this time of year, so at least you won't need a thick wetsuit.
Even then, the swell is small and inconsistent. Things are a bit flat. By the time we hit the start of September, conditions start to look a little cleaner, but the swell is still tiny. The only time things get a bit interesting is on the 4th of September. We've got a moderate swell building, with wave energy jumping to 749 (moderate), with 8ft swell from the ENE. That's a decent size, but the wind is cross-onshore and it's a bit choppy. The period is only 8 seconds, so it's a short-period wind swell, not the best shape. This is more for the experienced crew, as it's a bit too big for a beginner. Honestly, for the whole 16 days, there's not a single standout session. The best you can hope for is a few clean, tiny waves on the 31st of August morning with a light offshore, but you'll be fighting for scraps.
Bottom line: If you're a kitesurfer, the windier afternoons might be more interesting than the paddle surfing. For the rest of us, it's a waiting game.
Rusty.

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.
