The Lowdown
Alright, Rusty here again, talking Rehoboth Main in feet and miles per hour. This 16-day run is a tough one – there’s nothing good on offer right now, and it’s a long, frustrating gap before we even get a sniff of something rideable.
The wind is the killer. Day after day, it’s onshore or cross-onshore from the NE or E, blowing anywhere from 12 mph up to a howling 37 mph. That’s trashing the waves. Swell stays tiny – 1 to 3 feet for the first week – and the wave energy is weak, barely hitting 77. Periods are short, 4 to 8 seconds, so no power behind it.
We finally get some push starting Monday, September 21, with swell around 4 to 5 feet and periods of 7–8 seconds. Energy jumps to moderate levels (142 and 247), but the wind is still a strong cross-onshore at 25 mph, so it’s messy. Tuesday, September 22, swell hits 5 feet and energy is strong at 386–417, but again, the wind ruins it. That pattern of building swell and onshore wind holds through Wednesday, September 23 and into Thursday, September 24.
Thursday afternoon, September 24, is the only window that might be worth a look. Swell drops to about 4 feet from the E, period stretches to 11 seconds, and energy stays solid at 285. The wind eases to a light breeze from the NE (6 mph), so it’s only cross-onshore with small ripples. It’s still not clean, but it’s the best of a bad lot. This is the only day in the whole outlook that’s not labelled “poor,” and it’s still marginal.
After that, Friday, September 25, the wind cranks back up to 22 mph, swell drops, and we’re back to poor. Saturday and Sunday, September 26–27, are a write-off with near-gale winds. By Monday, September 28, the swell is tiny again.
This is a beach break exposed to the east, and when the wind won’t cooperate, it’s just not happening. For beginners, the swell never really gets too big (over 5 feet only for a couple of days), but the conditions are so bad it’s not worth it. Honestly, the setup looks more interesting for kite surfing than paddle surfing when that strong cross-onshore wind kicks in.
Keep an eye on the forecasts – things can turn around. But for now, leave the board at home.
Rusty.

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.
