The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Rehoboth Main is a tough one. The numbers don’t lie, and we’re looking at a long, quiet stretch with very little to get excited about. There’s a gap of several days right from the start with no real surf on offer, so don’t rush to grab your board just yet.
The water is sitting at 77°F with a temperature anomaly of 5°F, which is much warmer than normal for this time of year – feels like bathwater out there.
For Monday the 7th and Tuesday the 8th, it’s basically flat. We’re talking tiny 1.0ft to 1ft swells with weak combined energy (38 and 18), and the wind is cross-on or just messy. Not worth paddling out. Wednesday the 9th sees a spike in wind speed up to 19 mph from the SSW, but the swell is still pitiful at 3ft and a period of only 4 seconds – that’s wind chop, not surf. The setup is more interesting for kite surfing than paddle surfing.
The rest of the first week and into the second week stays stubbornly small. From Thursday the 10th through to Tuesday the 22nd of September, the swell heights rarely push past 2ft, periods are mostly short (4 to 8 seconds), and the combined energy is weak, sitting between 15 and 62. The winds are a mixed bag of offshore, cross-off, and cross-on, but the lack of size and power means you’ll be scratching for anything rideable.
There’s one tiny glimmer on Sunday the 13th of September. The early morning session shows a 1ft swell from the SE with a 10-second period, combined energy of 43, and glassy conditions. The forecast says “surfable waves but very ordinary conditions” – that’s the best we’ve got, and it’s not saying much. The wind is glassy, which is a positive, but the swell is just too small to get excited about.
For the rest of the run, especially from the 16th to the 22nd, it’s more of the same: small weak swells, poor surf conditions, and nothing that breaks the pattern. The 22nd of September has a 3ft swell from the NE with a 6-second period and combined energy of 61, but the wind is cross-off and the quality is still listed as “poor surf conditions.”
Honestly, this is a blank run. Rehoboth Main is a beginner-friendly spot, but even beginners need something to ride. There’s no standout session here. If you’re desperate, the glassy morning on the 13th is your best bet, but keep your expectations low. It tends not to stay this poor for long, but right now, the ocean is giving us nothing.
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.
