Round Rock Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window on the cards for Round Rock, and I’ll be honest, it’s a tough one. The whole stretch is plagued by a persistent cross-onshore wind that never lets up, keeping the ocean messy and lumpy. There are no standout sessions, no hidden gems—just a long run of poor surf conditions. The first real chance of anything remotely rideable doesn’t show up until the fourth of August, but even then, it’s a struggle.

Tuesday, August 4th kicks things off with a measly 3ft swell from the east, short period of 7 seconds, and a cross-on easterly breeze at 12 mph. The combined energy is weak (163), and the water is a warm 83°, which is about average for the time of year. But that’s where the good news ends—it’s just choppy and poor. Tuesday afternoon drops to 3ft, and the pattern holds through the week.

Wednesday, August 5th we’re down to 2ft in the morning, barely a ripple, with a risk of thunderstorms in the afternoon. The energy is gutless (55). Thursday, August 6th the swell bumps to 5ft, but the wind picks up to 19 mph, making it a lumpy, fresh cross-onshore mess. The combined energy climbs to 170, but it’s all noise.

Friday, August 7th through Sunday, August 9th is more of the same: waist-high slop, cross-on wind, and scores of zero across the board. The energy sits between 105 and 142—nothing to write home about.

Monday, August 10th and Tuesday, August 11th are similarly flat and weak, with swell around 2ft to 4ft and energy dropping as low as 76. The wind stays stubbornly cross-on.

Wednesday, August 12th we see a bit of a pulse, with the swell hitting 5ft again, but the wind is now 19 mph, making it fresh and lumpy. Energy is 121 in the morning, 253 in the afternoon. Still poor.

Thursday, August 13th the swell builds to 6ft in the morning, 6ft in the afternoon, with energy climbing to 414. But the wind is 19–22 mph cross-on, so it’s just a windy, choppy mess. This setup is more interesting for kite surfing than paddle surfing.

Friday, August 14th the swell gets to 8ft, with a period of 8 seconds, and energy hits 669. The wind is still 19–22 mph cross-on. This is solid swell, but the quality is zero—it’s a washing machine for experts only, and even then, the wind kills it.

Saturday, August 15th is the peak of the swell: 8ft in the morning, 8ft in the afternoon, with energy roaring to 890. The period is 8 seconds, wind is 19–22 mph cross-on. It’s a powerful, messy groundswell that’s only for the brave, and the long period (over 8 seconds) means it’s breaking straight at this beach setup. Not a good look.

Sunday, August 16th the swell drops to 7ft, energy 635, still cross-on at 19 mph. Monday, August 17th we’re back to 6ft, with risk of thunderstorms and energy of 361.

Tuesday, August 18th and Wednesday, August 19th see the swell fade to 5ft and then 4ft, with energy falling to 160–200. The wind finally eases slightly to 16 mph, but it’s still cross-on.

So, the bottom line: there’s not a single recommended session in the whole 16 days. The wind is relentless, the quality is always poor, and the swell direction never matches the optimum north direction for Round Rock. If you’re desperate, the 14th to 16th of August have the biggest swell, but it’s only for experts and the conditions are horrible. For the rest of us, it’s a blank run. This area can be like this—sometimes it just doesn’t line up. Forecasts can change, but right now, it’s a hard pass.

Rusty.
