The Lowdown
Howdy, it's Rusty. Let's talk about Rockpiles and what's brewing over the next couple of weeks. It's a real mixed forecast with a lot of windy days and less-than-ideal swell direction for this reef. Water temp is a balmy 80°F, which is pretty standard for the season.
We start off this Friday, July 24th, and honestly, it's not looking great. There's a 7ft swell from the ENE, but the period is a short 7 seconds, and we've got a stiff 25 mph cross-off wind. The wave energy’s moderate, but that wind is just going to trash it. The same windy theme carries through Saturday and Sunday. Swell drops a bit in height, but the wind doesn't let up. Saturday afternoon does bring in some long-period 18-second energy from the SSW, but it's only 3ft of it. That long period could make it line up well on the reef, but it's hard to get excited with the cross-off wind still howling.
Now, the one standout that has me waking up early is the morning of Wednesday, July 29th. We're looking at pure glass. The wind drops to a whisper at 3 mph from the west. We've got a clean 2ft swell from the south with a long 14-second period. The combined energy is weak, so it won't be pumping, but glassy, clean conditions on a reef with some period to it? That's the stuff. This is your morning to get a few good ones with nobody around.
After that window, it's back to business as usual. The ENE trades come roaring back on Thursday the 30th, and the swell builds, but the conditions get messy again. From August 1st through the 5th, we see a persistent 7ft to 8ft ENE swell with cross-off winds in the 18-25 mph range. That's some serious size on a reef, and with that wind, it's a heavy, challenging wave for the experts only. The energy is moderate to strong, but the quality is poor. There's a little pulse on the 2nd with a 4ft, 16-second swell, but, you guessed it, the wind is still cross-off. The outlook finishes the week with a risk of thunderstorms, a messy SE wind, and poor conditions rolling into August 8th. The long-range stuff on the 7th and 8th shows some long-period SW energy, but the stormy weather and wind keep the hope low.
Plain and simple: we've got one good, clean day on Wednesday the 29th for a small, glassy session. The rest of the period is mostly a wind-battle with short-period, choppy waves. When it's that onshore and blown out, this spot might be more fun for the kite guys than for a paddle surfer.
Keep your eyes on the forecast, and I'll see you out there.

Information about the Rockpiles Surf forecast
The above surf forecast table for Rockpiles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rockpiles can be found by selecting the local surf guide option on the grey menu. Our Rockpiles 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 (Rockpiles) 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 Rockpiles 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.
