Round Rock Surf Forecast and Surf Report

Alright, Rusty here. Let’s get into it. The outlook for this region is a tough one. Over the next 16 days, the wind is stuck onshore and sideshore, and that nasty cross-on flow just isn’t letting up. Every single time slot shows “poor surf conditions,” so there’s no real window to get excited about. We’ve got a long stretch of messy, choppy, lumpy water ahead. If you’re a paddle surfer, it’s going to be frustrating. A lot of these days with moderate to fresh breeze and cross-onshore wind are going to be more interesting for kite surfers than anyone on a shortboard.

Alright, let’s start with the first recommendation on the list, which is Round Rock. It’s a consistent, exposed spot that works best with swell from the N. On the morning of September 15th, you’ve got some clouds, a 16 mph NE wind blowing onshore, and tiny 3 ft swell from the ENE with a short period of 8 seconds. The combined energy is weak at 136, and the water temperature is a warm 85°, which is about average for this time of year. Nothing is working here.

Moving through the period, there are no standouts. The swell stays under 7 ft through most of September, with all the energy being funneled in by onshore winds. There’s a pulse on Wednesday the 16th morning where the swell jumps to 7 ft from the ENE (period 8 seconds, combined energy 517 – moderate energy), but it’s still cross-on and choppy with a 16 mph ESE wind. That size is getting into the intermediate zone, but the conditions are terrible.

Things don’t improve. Every day is a repeat of the same story: cross-on wind, moderate to fresh breeze, and poor surf quality. There’s a period from September 19th through the 22nd where the swell drops way down – 1 ft to 4 ft – and the combined energy sits below 100 or just barely into three digits. That’s a real gap of flat, weak conditions.

Late in the run, around September 28th morning, a longer period 12-second pulse from the NNE hits with a combined energy of 307, but again, the wind is fresh and cross-on, so you’re looking at lumpy, messy lines. The swell size is only 2 ft anyway. Not worth the paddle.

The biggest swell shows up on September 30th morning with 10 ft from the E at 9 seconds and a very strong combined energy of 1391. But at that height, and with a 12 mph cross-on wind and “poor surf,” this is for expert surfers only. And even then, it’s going to be a washing machine. Too big, too messy.

Honestly, there are no good surf options in the entire 16-day window. Round Rock is consistent, but with this non-stop onshore pattern and zero clean windows, you’re best off sitting this one out. The forecasts can change, but right now, it’s a full blank run.

Rusty.
