The Lowdown
Alright folks, Rusty here. Let’s chew over what’s on the table for Rehoboth Main over the next 16 days—and I gotta be straight with you, it’s not pretty.
We’re looking at a long, dry spell. From Wednesday 15 July right through to Thursday 30 July, the models are showing nothing but tiny, weak surf and almost no quality. The combined swell energy barely touches double digits for most of the week, creeping up to 73 (moderate) at best on Sunday 26 July morning, but that’s still only 3ft of messy SSE swell with a short period. Water’s sitting at about 75°, which is pretty average for this time of year (anomaly 2°F), but honestly, the lack of swell is the real story.
The first few days are hopeless—0.7ft ESE slop with gentle offshore winds on Wednesday morning, but the waves are just too small to bother. Thursday 16 July goes glassy but still 0.7ft. Friday 17 July gets a tiny 1ft bump from the SSE but cross-shore winds mess it up. Saturday 18 July afternoon sees the biggest swell of the whole run: 3ft from the SSE—sounds promising until you see the period is a pathetic 4 seconds. That’s windswell, no push, and the combined energy is just 38. With glassy conditions it might look clean, but it’ll be weak and wobbly.
Even the so-called “surfable but very ordinary” moments—like the morning of Saturday 25 July with 2ft SE and offshore WNW wind—are barely worth a mention. The best we get is maybe 3ft on the afternoon of 25 July, but the period drops to 4s again. Sunday 26 July morning hits 3ft with 7s period and cross-off NNW wind, energy 73—that’s the best combo of the whole window, but it’s still only waist-high slop. And by then, we’re ten days out, so treat it as a long-range whisper.
Crowds? Rehoboth Main is always packed, and with almost nothing to ride, the line-up will be full of beginners on foamies. The break is exposed to everything and fairly consistent, but when the swell is this weak, consistency means nothing. Honestly, this stretch looks more suited to a lunchtime paddle than a proper surf.
If you’re desperate, keep an eye on that 26 July window, but I wouldn’t hold my breath. Forecasts can change, sure, but right now it’s a total dud.
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.
