The Lowdown
Hey folks, Rusty here. Gotta be straight with you – the outlook for the next two and a bit weeks is pretty grim. There’s a long, long stretch of nothing much to get excited about, so let’s just take it day by day.
We’re starting off with a real flat spell. From Friday the 17th right through the following Tuesday the 22nd, it’s a write-off. Tiny, weak waves, and the wind is all over the place. The only slight glimmer is a bit of a bump on Wednesday the 22nd at Rehoboth Main. It’s not much – a 3ft SSE swell sneaking in, but it’s got a moderate offshore wind from the W keeping things clean. The combined energy is weak though, only 102. It’s a surfable wave, but it’s very ordinary. The water temperature is a touch warmer than normal at 76°, but that’s about the only positive.
From there, it’s back to the salt mines. The rest of the week into the weekend and the following week is just a whole lot of tiny, often choppy, poor surf. There are a few moments of glassy conditions on Thursday the 23rd afternoon and Saturday the 25th morning, but with waves only 2ft to 2ft, it’s more about messing about than a proper session. The best you can hope for is a “surfable but very ordinary” kind of day.
Looking further out, the first of August doesn’t offer any relief either. The swell stays tiny, under 2ft, and the wind is mostly onshore or cross-onshore. The combined energy is barely registering, stuck in the 40s and 50s. Honestly, for this stretch, if you’re desperate for a paddle, you might find a tiny, clean ripple on the 26th morning with a light offshore, but it’s a real struggle.
The standout? There isn’t one. This is a bare-minimum run. The only time you might want to get wet is Wednesday the 22nd morning for a few clean, small waves, and even then, keep your expectations low. For the rest of it, it’s a case of watching the tide come in and go out.
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.
