The Lowdown
Alright folks, Rusty here. Let’s talk about Rehoboth Main. This one’s gonna be a bit of a waiting game, to be honest.
The overall pattern over the next couple of weeks is pretty subdued. There’s no real fire in the ocean for a long stretch. Most of the time we’re looking at tiny, weak waves, often with onshore or cross-shore winds messing up the lines. You’re gonna have to scratch around for anything decent.
Let’s break it down. Starting off on Sunday, September 13th, we’ve got tiny 2 to 2 ft swell (5 to 10 second period) coming from the southeast. The real killer is the weather – there’s a risk of thunderstorms. Sunday morning is cross-offshore but the energy is super weak, and Sunday afternoon is glassy but the swell is just too small at 1 ft to get excited about. Water temp is sitting at 76°, which is much warmer than normal for this time of year – a solid 5° above average. That’s a nice bonus if you’re just paddling around, but the surf itself is a letdown.
Moving into Monday the 14th and Tuesday the 15th, the swell drops even more, barely hitting 2 ft, with a period of just 6 to 9 seconds. The wind is a problem too – strong northerlies and then onshore easterlies keep things choppy and messy. No good.
There’s a bit of a teaser on Thursday morning, September 17th. We get a clean 2 ft wave from the east (8 sec period) with a light cross-offshore wind from the SSW. It’s surfable, but it's tiny. The energy is still weak. It’s really just something to get wet on, not a session to write home about.
After that, it’s pretty much a flat spell or poor quality into the third week of September. The swell stays pathetic, under 2 ft, and the wind keeps shifting around but never really settles into a clean offshore for any length of time. The 21st and 22nd see a bump in swell height (around 3 ft to 5 ft) but the period is short (6-7 seconds) and the wind is a strong, messy onshore gale. Fresh cross-onshore and lumpy all the way. Not fun.
Now, late in the window, around September 25th and 26th, the swell picks up, but don’t get your hopes up. We’re looking at 6 ft to 6 ft swell from the east-northeast, with a period around 10 seconds. That’s got some decent push behind it, but the wind is a real buzzkill – strong cross-onshore from the Northeast at 22 to 25 mph. If you’re on a surfboard, it’s going to be wind-affected and choppy. Honestly, with those conditions and the beach-break setup, this looks more interesting for a kite surfer than a paddle surfer. The waves are there, but the quality is gone.
If you have to choose, the Thursday morning of the 17th is probably your best bet for clean, rideable waves, but it’s not a standout. It’s just the least bad option. The rest of the forecast? A lot of waiting around.
Keep the rubber on, check the charts. Sometimes it turns quick. For now, it's a quiet spell in Rehoboth.
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. 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.
