Table - best surf conditions forecast for Rockpiles over the next 16 days.
Alright, let’s get into it, but I’ll keep it in feet and miles per hour.
First up, this is a rocky road for us. Rockpiles is a reef setup, fairly consistent, and the optimum swell direction is SSE. But what we’re seeing for the next week and a half is mainly a strong, blustery ENE cross-off wind, which is going to mess with things. The water temp is sitting at about 79°, which is bang on average for this time of year, so no surprises there.
From Thursday the 9th through the weekend, we’ve got some sizeable swell, 6 to 8 feet, but with short-period, wind-affected ENE swell – around 7 to 8 seconds – and those strong cross-off breezes from 22 to 25 mph. The combined energy is moderate to strong (469 to 978), but the wind will be putting a nasty chop on it. The reports all call it poor surf conditions, so it's a hard pass for a paddle. Honestly, with that wind and the way the waves will be breaking, this setup looks more interesting for kite surfing than paddle surfing.
We get a glimmer of hope on Monday the 13th and Tuesday the 14th, with marginal conditions and some score 1 out of 10. The wind eases a bit from Tuesday on, but it's still cross-off, and the swell stays short-period and bumpy. Not worth getting too excited about, the break quality just won't be there.
Then, the real standout appears. Look at Tuesday the 21st and Wednesday the 22nd of July. This is the one to circle on the calendar. A proper long-period groundswell starts to show, coming from the east with a period of 16 to 19 seconds. The combined energy here is strong to very strong (1206 to 1728). That's a powerful, long-period E swell. Now, Rockpiles likes SSE direction, and this is E, so it's not going to be perfect on the angle, but the quality of the energy is a game-changer. The wave heights will be 4 to 4 feet, which is a super fun size for experienced surfers. The wind stays cross-off from the ENE at 19 mph, which isn’t clean offshore, but it should keep the faces reasonably groomed compared to the gale we had earlier. This long-period swell will work best on the reef, but be aware it can break a bit flat and straight on a beach, but here at Rockpiles it should offer some real power. The forecast is still a week and a half out, so things could shift, but right now this is your best bet. It's still only scoring a 2 out of 10 for "marginal" conditions, but that's positive for this spot in this forecast. The crowds are "sometimes" a factor here, so you might get it with a few friends.
After that, from Thursday the 23rd, it all fades back into small, weak windswell. Nothing to write home about.
The pick of the bunch is definitely Tuesday the 21st and Wednesday the 22nd of July at Rockpiles. It won't be perfect, but it’s the only one with real grunt and a hint of quality.

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.
