The Lowdown
Alright folks, Rusty here. Let’s get stuck into this one.
Honestly, looking at the next 16 days for Rehoboth Main, it’s a tough stretch. The pattern is pretty flat for the majority of the period. The surf is basically non-existent right through until mid-September, with hardly anything worth paddling out for. The first few days are all tiny, weak waves with minimal energy, and the wind is a bit of a mixed bag. There’s a real gap here – from the start all the way through to the 16th of September, there’s nothing that’s going to get your heart racing.
The first real sign of something happening comes on the 16th of September. The swell bumps up a little with a combined energy of 107, but it’s all from the ENE at 4ft and a short period of 5 seconds. The wind is a fresh cross-onshore, making it lumpy and messy. It’s still poor surf conditions, not really worth a look.
The swell continues to build a bit through the 17th and into the 21st, but it’s all short-period, wind-affected stuff. The 21st of September shows a bit more size, with swell hitting 5ft and combined energy up to 204, but it’s still on the cross-shore wind and the period is short. It’s not clean.
The stand-out of the whole outlook, if you can call it that, is the 22nd of September. The swell is the biggest of the period at 7ft from the ENE, with a combined energy of 426. That’s a moderate energy level, but the period is only 8 seconds, so it’s not a proper groundswell. The wind is a gentle cross-onshore, so it’s going to be a bit choppy. For a beginner, 7ft is on the big side, and with the short period and onshore wind, it’s not going to be a classic day. It’s the most energy we see, but the quality is just not there. The water temp is about average for this time of year, nothing wild.
Overall, it’s a quiet period for Rehoboth Main. There’s no real hidden gem here. The setup is a beach break, and with the wind and swell angles we’re seeing, it’s more likely to be a bit of a mess than a clean, rippable wave. You’d be better off with a kiteboard on those bigger, windier days.
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.
