The Lowdown

G'day, I'm Rusty, and I've got a look at the surf ahead for Rockpiles. It's a reef setup, pretty exposed, and it likes a swell from the SSE direction. The water temp is sitting at 81°, which is about normal for this time of year, nothing crazy.

The first week is a bit of a write-off, to be honest. We've got a big gap from now until later in the period before anything really stands out. The early part of August is plagued by a stiff cross-off wind from the ENE, mostly 19 to 25 mph, which just kills the quality. The first few days offer tiny 1 ft SW swells, but the conditions are poor. From Saturday the 8th through to Tuesday the 12th, we get some size, say 5 ft to 6 ft, but it's short-period ENE wind swell (6-8 seconds) and the wind is just too strong to make it any good. It's mostly "poor" or "marginal" with energy levels moderate, like 500-600 (combined energy). Honestly, with that wind and the beach setup, it looks more interesting for kite surfing than paddle surfing for a lot of this stretch.

Now, the real standout is shaping up for Wednesday the 19th of August. That morning the wind drops right back to a gentle 9 mph breeze from the E, still cross-off, but much cleaner. The swell is a solid 6 ft from the ENE with a period of 9 seconds, not huge but decent shape. The combined energy is moderate at 510. This is your best bet for a clean, fun session. The forecast suggests very good surf conditions, and while there's a little crowd potential, the quality should be worth the company.

Looking further to Saturday the 22nd of August, we get a switch. The wind stays light, around 9 mph, and the swell direction goes to the SSW with a longer period of 16 seconds. It's a smaller swell, 2 ft to 2 ft, but that long period groundswell carries some punch. The combined energy is moderate at 491. This is a promising option for the second week, but keep in mind forecasts that far out are less certain. For a reef break like Rockpiles, that longer period could line up nicely.

So, to sum it up: the first week is a washout due to wind. The absolute best on offer is Wednesday the 19th of August for clean, fun waves, with the Saturday the 22nd of August as a promising, smaller, long-period option to keep an eye on.

Rusty.

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.
