The Lowdown
Alright, Rusty here. Let's have a look at what Rimini's got cookin' for us.
Honestly, I gotta level with you. We're looking at a pretty flat run over the next 16 days. The numbers are just not there for any real surf. The water is a stinking 85°F which is way warmer than usual for this time of year, like a bathtub, but that's about the only interesting thing.
We start off on Tuesday the 18th with nothing. The first tiny bump shows up on Thursday the 20th, but it's a joke. We're talking about a 0.7ft to 1ft wave from the east-southeast with a period of 3 to 4 seconds. The combined energy is a measly 2. It's pretty much a lake. The wind on Thursday morning is light offshore from the southwest, so it'd be clean, but there's just no power behind it.
Friday the 21st is a bit of a tease. The afternoon has a 2ft wave from the same east-southeast direction, and the period bumps up to 5 seconds, with the energy hitting 12. It's still tiny, but the wind goes glassy from the west-northwest, so it'd be a slick, clean surface. You'd be scratching for anything, but you might find a little knee-high closeout.
Saturday the 22nd morning is glassy calm, but the wave is only 1.0ft. Then Tuesday the 25th afternoon, the wind swings hard from the west at 19 mph, creating a messy cross-offshore wind. There's a 2ft wave from the northeast with a 5-second period and energy of 12, but that wind is going to be a battle.
The rest of the outlook is a total write-off. There are long gaps of days with absolutely no surf on offer at all. From the 27th of August right through to the 2nd of September, it's basically a flat spell. You'll see a few days with a 0.7ft bump, but it's not worth paddling out for.
The bottom line: Rock Island (Rimini) is a beginner-friendly spot, and it's fairly consistent, but even for a beginner, there's nothing to work with here. The swell is too weak, the energy is too low, and the periods are too short. The only standout is the Friday afternoon glass-off, but even that's a stretch. Don't bother getting the wetsuit wet. This is a kite surfer's dream for a few of those afternoons with the strong cross-offshore wind, but for a paddle surfer? Forget it.
Rusty.
