The Lowdown
Howdy, Rusty here again. Let’s get straight into it – for the next 16 days at Rehoboth Main, the surf is mostly on the tiny side. It’s a long stretch of knee-slappers and flat spells, so you’ll need to be patient.
The best chance for a wave comes on Wednesday 19th August morning. That morning shows a bump of 3ft out of the SE with an 11-second period, bringing the combined energy into the moderate range (236). That’s the strongest push we see across the whole outlook. With a gentle cross-shore breeze it’ll be ridable, but nothing to get excited about – small, clean enough for beginners. It’s a beach break, so don’t expect the drop-ins to last long.
From August 13th through the 18th, it’s flat to tiny. Swells barely reach 0.3ft to 2ft, period often under 10 seconds, and combined energy weak – well under 100 most of the time. Winds are messy, mostly cross or cross-on, with a few clean windows. Even the cleanest morning on the 17th only has a 2ft swell and combined energy of 41 – barely enough to stand up.
Then from 19th afternoon all the way to the 26th, the surf completely dries up. Heights stay between 0.7ft and 2ft, periods short to moderate, combined energy low – often below 50. A few mornings have glassy calm conditions but no swell to match. This is a real blank patch.
Late in the outlook, on Thursday 27th August morning, a short-period wind swell builds to 5ft out of the ENE with a 7-second period. Combined energy hits 171 (moderate). Wind is cross-onshore though, so expect lumpy, messy waves. By afternoon it’s 6ft with onshore wind, energy 263 – plenty of water moving but blown-out. Friday 28th holds around 5ft to 4ft but with onshore flow again. That late spike looks more suited for kite surfing than paddle surfing – too rough and crumbly for a clean ride.
So Wednesday 19th morning is your best bet, and even that’s just an average session for a beginner. Water temp is about 79°F, which is a touch warmer than normal for this time of year – nice for a long float. Crowds at Rehoboth Main are always around, even when it’s flat, so don’t expect solitude.
It’s a slow run, but the ocean has a way of changing its mind. Stay hopeful.
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.
