The Lowdown

Right then, let’s talk about Rehoboth Main. I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for any kind of decent surf. You’ll be looking at a long stretch of tiny, weak, and just plain poor conditions.

The first real chance of something, and I mean a slim chance, doesn't show up until Monday the 31st of August. There’s a little bump of energy coming through, with a combined swell energy of 50 (moderate). It’s small, at 0.7 ft, but it’s coming from the ESE, right on the money for this break, with a *very* long period of 19 seconds. The wind looks clean and offshore from the WSW in the morning. That’s the standout, but that wave height is pitiful. The water temp should be about what you’d expect for the time of year.

Before that, it’s all tiny windswell and onshore junk. The afternoons might occasionally clean up, but the wave heights are barely a ripple. From the start of September, we see a similar pattern: occasional periods of light winds or glassy conditions, but the swell just isn't there. The combined swell energy mostly stays well below 100 (weak), with some smaller readings in the teens and twenties.

Let’s be clear: there are no proper waves on offer for the vast majority of this 16-day window. The highlight, if you can call it that, is that Monday the 31st morning. It’s a long-period groundswell from a good direction, and the wind will be glassing it off. But at 0.7 ft, it’s not even surfable for a log. It’d be a long, flat paddle for nothing. After that, the energy ticks up a bit on the 31st afternoon, hitting a combined swell energy of 160 (moderate), but that’s still only 1 ft from the SE. The morning of the 2nd of September looks glassy again, but again, the swell is flat.

Basically, the board stays in the car, or on the rack. This is a blank run. For a spot that's usually fairly consistent, this is a proper dry spell. We’ll see if the forecasts change, but for now, don't hold your breath.

A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu. Our Rehoboth Main surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
