The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Rehoboth Main. I’ll be straight with you – it’s not looking like a classic week on the sandbars.
Right now, and all the way through the 16-day window, we’re stuck in a bit of a flat spell. There’s simply no surf to get excited about. The combined swell energy tops out at a weak 204 (on August 10th) but even that comes with poor conditions. For the vast majority of the period, the energy sits well under 100 – we are talking 20s, 30s, and 40s – which is weak. You’d be hard-pressed to even get a rideable bump.
The consistency is there for the spot, but the waves are tiny. From now through to the end of July and into the first week of August, we’re looking at summery, knee-high dribble at best. The swell direction is mostly out of the SE or SSE, with a short, weak period of 4 to 8 seconds, meaning no real push or shape.
Wind is a real mixed bag. There are a few moments of flat calm, like the morning of Saturday August 1st with glassy conditions and the morning of Saturday August 8th, also glassy. But with swell at 1 ft, there’s just nothing to ride. Most other sessions are ruined by onshore or cross-shore breezes, turning any ripple into chop.
Monday August 5th morning shows a slight pulse – 4 ft from the S with a period of 7 seconds and light cross-onshore wind. Combined energy hits 198, which is moderate, but the wave comment still reads “poor surf conditions” and the rating is a flat zero. Similarly, Monday August 10th morning shows 4 ft from the ESE with a 7-second period, and energy at 204. But again, onshore wind and a zero score.
So, I can’t even recommend a standout session here. For a beach break like Rehoboth Main, this setup is more interesting for kite surfing than paddle surfing. There’s just no quality swell on the cards.
The water temperature anomaly is not mentioned in the data for the first break so I can’t comment on that. Crowds at Rehoboth Main are listed as “always”, but frankly, there won’t be a soul in the water for this.
Hang in there. It tends not to stay this poor forever. Forecasts can change. 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.
