The Lowdown
Alright, Rusty here again. Let’s talk about what’s going on in feet and knots.
This stretch starts off real quiet. There’s a long dry spell with nothing worth paddling for until late August. The first little pulse shows up on the 27th of August, but it’s only 2-3ft from the SE with a cross-onshore breeze and moderate energy (105). Not a standout.
The best window comes on the morning of Friday the 28th of August at Rehoboth Main. We’ve got a 2ft swell out of the S, with an offshore wind from the W making it clean. The period is short at 6 seconds, so the waves are weak (46) but for a beginner, it’s about as good as it gets. The afternoon goes glassy with the same 2ft, which is a nice little session. Water temp is running a touch warmer than usual at 77°, a bit above average for the time of year.
After that, the 1st of September brings a 4-5ft swell from the ESE, but the period is still short (6 seconds). The wind is cross-offshore, and the energy hits 270 (moderate). It’s only marginal, not a standout. Then on the 2nd of September, it drops to 1-2ft with a long 12-second period from the SE, clean winds, and moderate energy (122). Surfable, but small.
The rest of the run fades into tiny 0.5-1ft dribble. If you’re a beginner, the 28th of August is your day. For everyone else, it’s a waiting game.
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.
