The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this look at Rehoboth Main is a bit of a bummer for the next couple of weeks. We’ve got a long, quiet stretch ahead with very little on offer, and when the swell finally does show up, the wind is going to trash it.
The water temperature is a standout though, sitting at a very unusual 77°F, which is much warmer than normal for this time of year. That’s about the only thing to get excited about.
The forecast is basically a blank run for the first week and a half. From Wednesday the 9th right through to the morning of Saturday the 19th, the surf is small and mostly junky. We’re looking at tiny waves, mostly under 3 ft, with short, weak periods. The wind is a mess – cross-shore, onshore, and choppy – so you’ll be battling a lumpy, bumpy ocean. The combined energy is weak, reading mostly under 100, which is a dead giveaway. There’s a brief window on Sunday morning the 13th with a clean cross-offshore breeze, but the swell is still only 2 ft with a pathetic 5-second period, so it’s barely surfable. Not worth paddling out for.
The only real change comes on Saturday afternoon the 19th when the swell starts to build. We get a bump up to 5 ft from the ENE, with combined energy jumping to 167. But the wind is still a moderate cross-onshore, making it choppy and messy. The comment says it’s “poor surf conditions,” so don’t get your hopes up.
The best of a bad lot looks to be Sunday the 20th. The swell holds at around 4 ft to 4 ft from the E, with a better 8-second period, and the combined energy is solidly moderate at 182 on the morning and 217 on the afternoon. The morning has a clean cross-shore breeze, but it’s a bit choppy. The afternoon has a light cross-onshore with small ripples. It’s a marginal day, but it’s the only time in the 16 days where the swell size and energy are half-decent. Still, for a beginner spot like Rehoboth Main, this is going to be a messy, closed-out shorebreak.
After that, the wind goes onshore and fresh, and by the 24th the swell is up to 6 ft from the ENE, but with a fresh cross-onshore and lumpy conditions. That’s a lot of power (combined energy of 780!) but terrible quality. At that size and with that wind, it’s a full-on mess – definitely just for experts, if anyone at all.
All in all, this is a tough stretch. The water is warm, but the waves aren’t playing ball. You’d be better off finding a sheltered spot or taking a break.
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.
