The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s goin’ on at Rehoboth Main.
Right off the bat, the next week and a half is a tough stretch. Tiny, crummy waves with no quality to speak of, so you’re better off keepin’ the board in the car. There’s a long flat spell with nothin’ worth paddlin’ out for. Water temp is sittin’ around 77°, which is a touch warmer than usual for this time of year.
The light at the end of the tunnel comes around Friday, September 4th. That afternoon we’ve got a clean 3ft swell from the SE, and the wind goes glassy out of the NW. Combined energy is 364 (moderate), so there’s some proper juice behind it. It’s a beginner-friendly spot, so the size is just right for a fun, clean session.
Saturday, September 5th morning is another standout. Swell bumps up to 4ft from the ESE, glassy conditions, with energy at 377 (moderate). That’s the pick of the whole forecast: clean, fun waves, and a touch bigger. Just make sure you’re out early, ‘cause the wind goes onshore and messes it up by the afternoon.
Thursday, September 3rd afternoon sees a build-up with 3ft from the SE and clean cross-off breeze from the NW, but it’s still a bit small. Energy hits 248 (moderate), so you can feel the ocean gettin’ ready.
A couple of tiny, clean mornings pop up before that, but they’re barely worth mentionin’.
Bottom line: wait for Friday the 4th and Saturday the 5th. That’s where the goods are.

Information about the Rehoboth Main Surf forecast
The above surf forecast table for Rehoboth Main provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Rehoboth Main) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
