The Lowdown
Oi, Rusty here. Let’s be straight with you—this stretch at Roc San Cayetano is a tough one. The whole 16-day window is a flat, frustrating run. There’s nothing to get excited about, and I’ll walk you through it.
Right now, Tuesday morning has absolutely no swell at all—zero energy, just a glassy, clean surface with water sitting at 84°, which is a solid 5° warmer than usual for this time of year. That’s much warmer than normal, but it doesn’t help the surf. The afternoon won’t change things, just a tiny 0.3 ft SE windswell, weak and onshore.
Wednesday morning sees a brief pulse of 1 ft SSW swell, but with a period of only 3 seconds, it’s junk. The afternoon stays marginal at 2 ft. Thursday picks up a bit to 4 ft SSW, but that’s still poor quality, and the wind swings cross-shore, messy. By Friday, we’re back to zero.
From Saturday the 22nd through to the end of the run, it’s a desert. The swell never gets above 3 ft, and it’s always short-period, choppy, or just flat. The combined energy is pathetic—mostly single-digit or low double-digit numbers (like 13, 17, 40, 71). The best you’ll see is 3 ft to 3 ft on the 23rd, 24th, and 30th, but with winds from the ENE or ESE, it’s either cross-off or cross-on, never truly clean. The wave comment is always “poor surf conditions.”
Roc San Cayetano is a point break that rarely breaks, and this forecast proves it. There’s no standout, no reason to paddle out. If you’re serious about a wave, you’re better off waiting for a change in the forecast. For now, it’s a flat spell that’s more normal for this area than a surprise.
Rusty.
