Alright, Rusty here again. Let’s break it down in feet and miles per hour for the Rockpiles.
Honestly, this is a tough outlook. We’ve got a full 16 days, and there’s just no real window for a good paddle-out. The whole stretch is dominated by a cranky cross-off wind and messy, short-period swell.
From Sunday the 5th through Saturday the 11th, it’s a washout. The swell is small windswell from the east-northeast, running about 2 to 3 feet, but it’s wrapped in a relentless 25 mph cross-off breeze. The water looks clean from the sky, but the surface is a mess. The combined wave energy is moderate, sitting between 443 and 878, but it’s all poor-quality, lumpy junk.
The only hint of something decent pops up on Sunday the 12th and Monday the 13th. We get a long-period groundswell from the southwest, with a 16-second interval and a clean 3-foot face. This is the kind of swell a reef like Rockpiles loves, and the direction (SSW) is a decent fit for the optimum SSE. But the wind remains stubborn – a 20 mph cross-off keeps it from being clean. It’s rated as marginal. That’s the best the whole period offers, and it’s not saying much.
From Tuesday the 14th onward, it’s back to the same story: ENE winds at 15 to 20 mph, short-period 2 to 3-foot waves, and poor-to-marginal scores. The wind does ease a touch toward the end, but the swell gets even weaker. Anything over 5 feet is short-period windswell, which is really only good for the kite crowd.
So, I’m calling it: this is a flat spell. Don’t hold your breath. The reef’s not going to deliver anything worth the paddle for a while.

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.
