The Lowdown
Alright, let's dig into this. Truth be told, the next couple of weeks are looking pretty grim for any decent waves. I'm really scratching my head to find a bright spot. That steady onshore wind is just killing everything.
We roll into Saturday the 12th with some clouds and a cross-onshore breeze out of the east at 16 mph. There's a 5 ft swell, but it's short-period windswell at 7 seconds with weak to moderate energy (301), and it's just gonna be choppy and unappealing. Poor conditions all around.
Sunday the 13th and Monday the 14th aren't any better. We've got a risk of thunderstorms and lumpy conditions. The swell sits around 5 ft to 4 ft from the east-northeast with 7-second periods, but that wind stays cross-onshore from the east at 13 to 16 mph. Expect moderate cross-onshore chop.
Tuesday the 15th through Saturday the 19th is more of the same story. You'll see clear skies in the morning or some clouds, but that east wind doesn't take a break. Swell slips from 4 ft down to 3 ft, with periods at 6 to 7 seconds. The energy is weak to barely moderate (141 down to 121). A frustrating, surf-less stretch.
We hit rock bottom on Sunday the 20th, with the swell dropping to just 2 ft in the morning and a weaker 2 ft in the afternoon. Periods of 7 to 8 seconds with energy levels down to 62. That's just a ripple.
Monday the 21st shows a slight bump in energy (227) with swell around 3 ft, but the period jumps to 10 seconds from the east-northeast. But with the wind still cross-onshore, it'll be messy.
Then from Tuesday the 22nd into the start of next week, we're looking at another dip back down to 2 ft. The energy drops off again (80 and 67). The only thing that catches my eye is around Wednesday the 23rd and Thursday the 24th when the swell starts to push back up to 5 ft to 5 ft from the east. The energy climbs into the moderate range (up to 275), but unfortunately the wind picks up too, hitting a fresh 19 mph. Get ready for lumpy, blown-out surf.
This forecast runs all the way to Sunday the 27th of September, and it's just cross-onshore conditions from start to finish. The very best we might see is 4 ft of windswell with 7-second periods, but there's no clean, glassy window anywhere.
For Round Rock, there's absolutely nothing to get excited about. The ideal swell direction is from the north, and we're getting hammered from the east. Combine that with the constant east wind, and it's a total non-starter. The water temp is sitting at 85°, which is about usual for this part of the year.
Honestly, this is looking more like a week for kite surfing than paddle surfing. Leave your board on the racks.

Information about the Round Rock Surf forecast
The above surf forecast table for Round Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Round Rock can be found by selecting the local surf guide option on the grey menu. Our Round Rock surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Round Rock) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Round Rock may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
