The Lowdown
Alright mates, Rusty here. Let’s break down the next couple of weeks.
Gotta be honest, it’s a tough stretch. We’re looking at a long, flat spell after one small window. Don’t expect much.
The first chance to paddle out comes Thursday morning, August 6th, at Rehoboth Main. There’s a little south swell pushing in around 3ft, with a light cross-offshore wind from the SSW, so it’ll be clean. The wave energy is moderate (119), so it’s not going to be a powerhouse. Water temp is about 75°, which is normal for the season. It’s the best we’ve got, but it’s nothing special. Beginners will be fine on the size, but the quality is just average.
After that, it’s a real bummer. Friday the 7th has a bit of clean surf, but the swell is fading fast. Saturday the 8th has a morning of tiny 2ft waves with offshore wind, but it’s just not enough.
From Sunday the 9th all the way through to the end of the forecast, it’s a long stretch of nothing – flat, choppy, or just wind-blown. There’s a moment on Tuesday the 18th of August with glassy conditions and no wind, but the swell is barely 1ft – you’d be floating.
So, call it for what it is: Thursday morning the 6th is your only real shot, and it’s a small, clean but forgettable day. The rest is a long dry spell. Hang tight, and hope the models change their tune.
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.
