The Lowdown
Alright folks, it’s Rusty here, and I gotta be straight with you – the next 16 days at Rehoboth Main are looking pretty grim. We’ve got a long stretch of nothing much on the cards, so don’t be in a rush to grab your board.
The first wave of any real note isn’t showing up until Wednesday, July 22, but even then, it’s a marginal call. The morning will see a 4ft swell from the south, with a period of 8 seconds, and the wind is coming from the southwest at 16 mph, which is a clean cross-offshore breeze. The energy is moderate at best (219). It’s surfable, but only just. By the afternoon, the swell pushes up to 6ft from the south, still 8 seconds, and the wind stays clean and cross-offshore. The energy jumps to a strong 628, but the risk of thunderstorms is there. For a beginner spot, 6ft is pushing it, and given the conditions, this is really only for the more experienced crew.
Looking at the water, it’s a touch warmer than normal for this time of year – about 77°, with a positive anomaly of 3°, so it’s notably warmer than usual.
The rest of the run is a write-off. After the 22nd, we drop back into tiny, weak, and choppy conditions. There’s a brief moment on Tuesday, July 28, with a clean 2ft swell from the SSE, but with a short 6-second period and weak energy (43), it’s "surfable but very ordinary." Not worth the drive.
The whole period is a bust. From July 20 right through to August 4, you’re looking at one day that’s barely worth a paddle, and the rest is flat, windy, or messy. The combined energy values are mostly in the teens to low nineties – weak stuff. The best day on offer is Wednesday, July 22, with the afternoon seeing the most size and energy, but even then, it’s marginal. If you’re a beginner, stay home. If you’re an expert, you might find a couple of corners on that Wednesday afternoon, but don’t expect much.
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.
