The Lowdown
Alright folks, it’s Rusty here, and I gotta be straight with you—this outlook for the next two weeks is a tough one.
Right off the bat, we’ve got a dry spell. There’s nothing worth paddling out for until a glimmer shows up late on Wednesday the 22nd of July, and even that’s a stretch. The first real chance to get wet without feeling like you’re wasting your time doesn’t appear until the tail end of the run.
The water at Rehoboth Main is sitting at a warm 76°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing if you decide to go for a float.
Let’s break it down. From now through the 21st of July, it’s a total write-off. Tiny, weak swell, poor conditions, and a whole lot of frustration. The wind is mostly cross or cross-off, but there’s just no energy. The combined swell energy doesn’t crack triple digits, staying under 60 (59 max) most days. Nothing to see here.
On Wednesday the 22nd of July, the morning actually kicks up a bit, with a 4ft swell from the SSE, and a period of 9 seconds. The combined energy jumps to 219—that’s moderate wave energy and a step up from the rest. The problem is the wind is howling from the WSW at 19 mph, so it’s messy. The afternoon calms down with a light NW breeze at 6 mph, and the swell drops to 3ft with energy at 97. The comment says “surfable waves but very ordinary conditions,” and that’s about the best we get. It’s a small, clean window, but it’s not a standout.
Thursday the 23rd of July through the rest of the month, it’s back to small, weak, and mostly poor. The wind is often clean, but the swell just isn’t there. Heights sit between 1ft and 2ft, periods are short (4-9 seconds), and energy levels mostly stay under 60. This is a long stretch of flat to gutless conditions.
The only real highlight comes right at the very end of the outlook. On Tuesday the 28th of July, we get a little afternoon window that’s worth noting. The swell is small at 2ft from the S, with a period of 6 seconds, but the wind dies to glassy conditions out of the E at 3 mph. The combined energy is low at 37, but glassy wind on a summer afternoon is a rare treat. It’s clean, it’s small, and it’s about as good as it gets for the whole two weeks. For a beginner spot like Rehoboth Main, that’s actually a decent chance to get some soft, clean waves without the crowd stress too much—though crowds are listed as “always,” so expect company.
After that, the rest of the run into early August is more of the same: small, weak, and mostly cross-off or cross winds. The swell is tiny, and the energy is negligible.
So, to sum it up: the best on offer is Tuesday the 28th of July afternoon with glassy conditions and clean 2ft waves. The rest of the 16-day window is a long, flat grind. It’s not a terrible time for the area—it’s just a normal quiet spell.
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.
