The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Rock Island (Rimini). I’ll tell you straight up, this is a tough one. The entire 16-day window is looking pretty grim for any proper surf. We’ve got a long, dry spell with nothing to get excited about.
For the first week and a half, from the 9th right through to the 21st of September, the swell is basically non-existent. We’re looking at flat, poor conditions day after day. There’s a brief moment on the 12th where the swell bumps up to 4 ft from the ENE, but with a strong onshore wind and a combined wave energy of just 131 (moderate), it’s messy and not worth paddling out for. The setup is a beach-and-reef, and with that onshore breeze, it’s more of a kite-surfing proposition than a paddle-surfing one.
The water temperature is sitting about average for the time of year, nothing weird there.
After that, we get a tiny bit of life on the 22nd of September. The Tuesday morning shows a 4 ft swell from the NE, with a period of 6 seconds and a combined energy of 77 (weak). The wind is a light cross-onshore, which is just about okay. It’s a marginal surf forecast, maybe just about rideable for a beginner on a foamie, but it’s not what I’d call a session. The swell direction is from the NE, which is the opposite of the optimum (NNE) for this spot, so the waves won’t be well-formed.
Honestly, the best of a bad bunch is that Thursday morning, the 22nd. It’s small, weak, and the wind is only just passable. Don’t expect any quality. The rest of the window is a total write-off.
Hang in there. It won’t be flat forever.
Rusty.
