The Lowdown
Alright, Rusty here. Let's have a look at what we’ve got on the cards for Rehoboth Main. I gotta be straight with you, it’s a pretty quiet run for the next couple of weeks. The water is sitting at 25°, which is a touch warmer than usual for this time of year, so that’s a little bonus at least.
Right from the start on Saturday August 29th, it’s not happening. We’re looking at tiny 1ft mush from the SE, with a short 8-second period and a cross-on breeze chopping it all up. The combined energy is a weak 33, and the call is “poor surf conditions.” That theme carries through the whole first week. Sunday is more of the same, Monday, Tuesday... you get the picture. There’s a tiny window on Tuesday morning with a light cross-off breeze cleaning things up, but the swell is still just 1ft with next to no energy (14). It’s not worth paddling out for.
We get a bit of a breather around Wednesday September 2nd with a slightly longer period of 11 seconds for a short while, but the wind is a fresh 19 mph onshore, making it lumpy and ugly. The energy bumps into the 80s but it's just not going to be any fun. The whole first week is a write-off.
There’s a gap of several days with nothing to recommend. Honestly, Rehoboth Main is a consistent break, so this flat spell feels a bit cruel. The only hint of something happening comes way down the track on Saturday September 12th. The morning looks interesting – a 4ft swell from the ENE, but the period is a short 5 seconds, which is a real buzzkill. The wind is glassy, though, calm air, so it’ll be clean as a whistle. The combined energy is 91, getting into that moderate range, but that period means it'll be weak and crumbly. That afternoon, the wind picks up and it gets messy again.
Looking into the second week, things don't improve. There’s a morning on September 9th where the wind goes clean cross-off from the SSW, and the energy hits 116 (moderate) with a decent 11-second period on a 2ft SE swell. That’s the best the whole forecast gets, which isn't saying much. It’s surfable, but ordinary. If you’re desperate for a paddle, that Wednesday morning is your only real shot, but it’s not something to get excited about.
Honestly, this whole 16-day window is a dud. The best on offer is that September 12th morning with glassy conditions and a little bump, but with no period it’s going to be fat and slow. Don’t hold your breath. Forecasts change, but right now, I’d find something else to do.
Rusty.
