The Lowdown
Alright folks, Rusty here. Let's have a look at what’s on the menu for Rehoboth Main.
Honestly, for a good long stretch here, it’s pretty grim. We’re looking at a flat spell that runs from now, the 30th of July, all the way through to the 8th of August. That’s over a week of tiny, weak surf with hardly any energy to speak of. You’ll see a lot of poor surf conditions and scores of zero across those days, with the combined energy of all swells struggling to hit even 60 (34). The wind is mostly cross or onshore, and the swell is tiny—generally around 1 ft to 2 ft—so the boards are staying in the car.
Now, things start to get interesting around the 8th of August. On Saturday the 8th, we get a pulse of long-period groundswell sneaking in from the southeast. The morning is still a bit ordinary with winds from the WSW at 9 mph, but the swell is already pushing 3 ft and the combined energy jumps to 187. That’s ‘surfable but ordinary’ territory. But the real standout is the afternoon of Saturday the 8th. The swell holds at a clean 3 ft from the southeast, with a period of 11 seconds. That longer period gives the waves some proper shape and push. The wind drops to a glassy 3 mph from the southwest, which is a clean cross-off. That will make for some beautifully smooth, peeling waves. The combined energy hits 222, which is moderate but solid for this size. This is the best session on offer, no question.
Sunday the 9th keeps the momentum. The morning looks excellent with a 4 ft southeast swell at a long 12-second period, and a light cross-off from the northwest at 6 mph. The combined energy is up at 345, which is solid moderate energy. That’s going to be clean and punchy. The afternoon, however, gets a bit more mixed, with the wind swinging south and going cross, and the energy dropping to 294. It’s still surfable, but the morning session is where it’s at.
After Sunday the 9th, the wind turns onshore from the east and the swell gets messy. From Monday the 10th through Wednesday the 12th, we get consistent 3 ft to 4 ft southeast swell with that lovely 12-second period, but the wind is howling straight onshore at 12 to 16 mph, spoiling the surface completely. The wave energy is high (up to 409), but it’s all blown out. For a beach break like this, that’s going to be a washing machine. This setup looks more interesting for kite surfing than paddle surfing, to be honest.
So, to wrap it up: if you’ve got patience, the afternoon of Saturday, the 8th of August, and the morning of Sunday, the 9th of August, are your windows. Get out there for those clean, lined-up waves before it all goes to crap with the onshore breeze. Keep in mind, Rehoboth Main is a beginner-friendly spot, but when that swell gets a bit of period, it can offer some fun lines for everyone.
Take care,
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.
