The Lowdown
Alright, this is Rusty. Let's talk about what's on the table for the Rehoboth Main stretch.
Look, I'm not gonna sugarcoat it. The next week and a half is a proper flat spell. We've got a solid 13-day gap here where the surf just isn't happening. The swell is tiny, the energy is weak, and the conditions are messy. The first real chance to even *think* about paddling out doesn't show up until Wednesday, September 2nd, on the afternoon. That's a long wait.
For that Wednesday afternoon, we finally see a pulse of life. The swell is a meek 1 ft coming out of the SE with a period of 10 seconds, giving us a combined energy of (42). It's not much, but it's surfable. The wind will be a light offshore flow from the NW, which will clean things up. The water here is sitting at 77° with what's described as a "touch warmer than normal" for this time of year. It's a small window of ordinary waves, but after all that nothing, it's the only thing on the menu.
The following days are more of the same flatness, with a few glassy moments on the 5th of September, but the swell is still just a tiny 2 ft with a short period of 4 seconds. That's barely a ripple. Honestly, for the entire 16-day window, there isn't a single standout. The best you can hope for is a small, clean session on that Wednesday afternoon, but keep your expectations in check. The surf just isn't cooperating right now.
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.
