The Lowdown
Right, folks, Rusty here. Let's have a look at what's on the table for Rehoboth Main. I gotta be straight with you – the first couple of weeks are a bit of a struggle. The waves are just tiny, and we've got a long wait on our hands.
We kick off on Saturday, August 8th with a small 1ft south-east swell, but the cross-off wind isn't helping, and it's just poor conditions. This theme runs right through the next week. The swell stays under 2ft, with periods so short they’re barely a ripple. We get a few glassy moments on Monday afternoon and Wednesday afternoon, but even then, it's just too small to bother with. You’d be floating out there. The combined wave energy is in the weak zone the whole time – we're looking at numbers like 14 to 41. There's a real dry spell here, with no decent surf on offer for over a week.
Now, things start to look a little more interesting heading into the back half of the month. Wednesday, August 19th, we finally see some real energy creep in. The afternoon brings a 2ft SE swell with a period of 8 seconds, and the combined energy jumps to 110 (moderate). It's still surfable but ordinary.
The standout moment, and the only one worth getting your wettie on for, arrives on Thursday, August 20th. We get a 2ft swell from the SE with a period stretching to 11 seconds – that's proper groundswell. The combined energy hits 157, and with a light N cross-shore, the conditions will be alright. It's not huge, but it's the best shape and power we'll see. Then Friday, August 21st, the swell builds to 3ft from the SE, with a period of 11 seconds, and the energy rockets to 251 (strong). The problem is the rain showers and moderate cross-off wind will mess with the surface. Still, for the more experienced among you, that afternoon might offer a few fun ones if you can dodge the showers.
Look, for Rehoboth Main, a beginner-friendly spot that's always crowded, this isn't the time to get excited. The swell never gets over 3ft, so it’s fine for learners if you just want a splash. But for a proper surf, that Thursday, August 20th, is your best bet. After that, the swell drops back down. It’s a long wait for just a little bump.
Rusty.
