The Lowdown
G’day, Rusty here. Look, I’ll level with you—this 16-day run for Rehoboth Main is a flat spell. There’s no surf worth paddling out for. The whole window is a write-off, with every single session marked as poor surf conditions. The swell is tiny, rarely cracking 2 feet, and the energy in the water is weak—most days the combined energy sits below 100 (42, 34, 45, 32, 23, 19, 23, 19, 13, 48, 90, 85, 39, 33, 22, 20, 10, 7, 55, 39, 96, 78, 35, 17, 22, 30, 48, 60, 62, 47, 15, 16). That’s not enough to push a ripple, let alone a wave.
The water temp is sitting at 76°F for Friday morning, which is a touch warmer than normal for this time of year—about 3°F above average, so it’s noticeably warm but not extreme.
The first few days are a mess of cross-shore and onshore winds, with a risk of thunderstorms on Friday, and the swell direction is all over the place—ESE, ENE, SE—never lining up well with the optimum easterly swell direction. There’s a brief window on Thursday morning, September 3rd, where the wind goes offshore from the WSW at 9 mph, and the sea cleans up, but the swell is still only 1 ft with a period of 9 seconds. That’s ankle-deep at best, and the energy is just 39. You’d be standing on the beach squinting.
Things don’t improve. The second week is more of the same: tiny swell, mostly cross-shore or onshore winds, and a few glassy moments on Wednesday afternoon, September 9th, but again, only 1 ft of swell with 30 energy. It’s a lake. The crowds are always there at Rehoboth Main, but with no waves, they’ll be sunbaking.
The outlook is bleak. Rehoboth Main is a beginner-friendly beach break, exposed to the east, but it needs a pulse of swell to work. There’s nothing on the horizon. These blank runs happen, but forecasts can change—so keep an eye out, but don’t hold your breath.
Rusty.

A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu.

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.
