The Lowdown
Alright, Rusty here, right from the beach. Lookin' at the long-range for Rehoboth Main, and it's a tough one to call. We've got a whole lot of nothin' on the docket at the start, so you're gonna have to be patient.
For the next week or more, it's pretty much a dead zone. Tiny, choppy, and mostly blown out. The water temp is a crazy warm 76°, which is way warmer than normal for fall. Feels like a bathtub out there, but with no waves to enjoy it in.
The first real chance of somethin' decent doesn't arrive until Sunday, September 27th, in the afternoon. We're lookin' at some waist-high swell, about 4ft, coming from the ESE. The wind will be light from the NNW, so it should clean up nice. Combined energy is in the moderate range (206), so there's a little push behind it. It's not a massive swell, so if you're a beginner, the size is under 5ft, so you could have a crack, but it's the cleanest option on offer. Monday the 28th in the morning looks like a repeat, with the same clean cross-off breeze and ESE swell around 4ft (188 energy), so you could get a couple of decent sessions in.
Earlier in the run, on Thursday morning, September 24th, you might get a glassy, knee-high wave (around 3ft) with 130 energy, but it's just ordinary. The bigger news is the windswell that comes through on the 21st and 22nd of September. We get some chest-to-head-high waves (5ft to 7ft) and the energy jumps up (190 to 569), but it's blown to bits by strong east winds. For clean surfing, it's a no-go. That kind of wind and chop setup would be way more fun for a kite surfer than a paddle surfer.
So there's your lot. A long, slow start with a little glimmer of hope on the last Sunday and Monday of the month.

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. 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. 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.
