The Lowdown
Alright, let’s get into it. Rusty here.
First off, Rehoboth Main’s looking at a pretty lean stretch ahead. The next several days are mostly flat with tiny little windswells. The water is sitting at 25°, which is a touch warmer than normal for this time of year, so at least you won’t freeze while you’re sitting there waiting.
The whole first week is rough. Monday the 24th through Sunday the 30th, we’ve got swell heights barely scraping 3 ft, mostly around 0.7 ft to 2 ft. The combined energy is weak, between 14 and 86. Winds are all over the shop, from offshore to onshore to cross, but the problem is the waves just aren’t there. A couple of surfable windows pop up Friday the 28th morning with a 2 ft SSE swell and cross-offshore WSW wind, and Friday afternoon goes glassy with a 1 ft ESE swell. You *could* get a wave, but it’s ordinary – nothing to get excited about.
Then we get into the first half of September. There’s a tiny glassy window on Tuesday the 1st morning with a 1 ft SE swell and a 15-second period (moderate energy 71). Looks clean, but it’s just a whisper. The real story starts brewing around the 4th and 5th. By Friday the 4th, we’ve got 3 ft ESE swell with a 13-second period, but the wind turns nasty – strong breeze onshore from the NE, making it a total mess (energy around 185-196). Saturday the 5th sees the swell bump up to 5 ft-5 ft from the ENE with a short period of 6-7 seconds. That’s got some moderate energy behind it (259-309), but that strong cross-onshore wind will have it chopped and lumpy. That’s not a paddle surf day; that’s more of a kiteboarding setup if you’re into that.
The best of the bunch, if you can call it that, might be Monday the 8th morning. We get a 2 ft E swell with a 9-second period, light cross-offshore wind from the SSW, and it’s clean. Combined energy is 89 – weak. It’s surfable but very ordinary. For Rehoboth Main, this is as good as it gets in this outlook. The crowds are always there, so expect company even for small waves.
Overall, it’s a rough 16 days. No standouts. A few afternoons and mornings might give you something to ride, but don’t expect much more than a knee-high bump.

A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu.

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.
