The Lowdown

Alright, grab your board and let’s get into it. It’s Rusty here, and I’ve got the full picture for the next couple of weeks for our stretch of coast.

Right now, we’re looking at a pretty flat and quiet run of surf. The swell is tiny, and the energy is pretty much non-existent. We’ve got a few days of clean but tiny conditions, but honestly, it’s not going to be worth paddling out for much. We’re talking about a real lull from now until the weekend. There’s a couple of small, clean windows with light offshore winds, but the waves are only around 0.6ft to 1ft, so it’s boards and beach time, not surfing.

The first real, but weak, pulse of energy shows up late in the first week. By Friday the 21st, we see a slight bump to 3ft, but it’s coming from the NE with a short, weak period. The winds are going to be messy and there’s a risk of t-storms, so the quality won’t be there. It’s not what we’re after.

We then have to sit through a few more days of small, onshore slop. The surf remains pretty poor and uninviting. It’s a frustrating stretch, but that’s the coast for you sometimes.

Finally, towards the end of the window, things start to wake up a little. On Sunday the 30th, we see the best of the lot, but it’s still not huge. The swell builds to 4ft to 5ft with a moderate energy (155 to 199). The direction is from the ESE, which is okay, and we get a proper offshore wind out of the WSW and W. This will clean things up nicely. This looks like the standout, but it’s a week and a half away, so don’t get too excited yet. It’s promising but less certain. It should be surfable, but it’s not the kind of swell that will get your heart pounding. It’s more of a “get wet, ride a few” kind of day.

For the featured spot, Rehoboth Main, we’re looking at a bit of a washed-out period. The water is running a touch warmer than normal at 78°, which is nice for those long waits between sets. It’s an exposed beach break, so it can get onshore quickly and the crowd is always a factor there. When it does clean up with that offshore wind on the 30th, that would be the time to go, but you’ll be sharing it with everyone else who’s been waiting.

Before that, there’s one small window on Monday morning the 17th with light offshore wind and a 3ft swell, but the energy is weak (37) and it’s inconsistent. It’s not really a standout, more just a chance to get a few clean little waves if you’re desperate.

For the last few days of August, the swell picks up a bit in size but comes with more cross-shore and onshore winds, so conditions will be choppier. The 30th remains the best bet.

Overall, it’s a flat spell with a slight lift at the very end. Manage your expectations and keep the board waxed for the 30th.

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.
