The Lowdown

Alright, Rusty here. Let’s have a look at the coming days for Rockpiles.

The next 16 days start off with a bit of a tease. Good, solid swell on the way, but it’s paired with some strong cross-off winds that will keep things from being truly clean most of the time. The first real standout is a single session on Wednesday the 29th.

We’ve got a steady pulse of easterly swell building through the weekend. It’s mostly 3 to 5 feet, but the wind is a fresh breeze from the ENE, blowing cross-off. That’s clean enough, but the wave energy is a bit average, sitting around 1200 to 1300. It’s not going to be terrible, but it’s not the session to write home about. The water temp is about where you’d expect for this time of year, nothing wild.

The real moment comes on Wednesday morning, the 29th. The wind drops to a glassy 3 mph from the NE. That’s offshore for Rockpiles, and it’s going to be magic. The swell bumps up to 8 feet from the ENE, with a period of 11 seconds, and the combined energy hits 1948 – that’s a decent push. The setup is a reef, so that period will bring some nice, lined-up waves. This is for experienced surfers only at that size, but if you’re in the game, this is the session. The afternoon sees a drop in size to 2 feet from the S with a 14 second period, but it’s glassy again. A different, smaller, cleaner option.

After that, it’s a real mixed bag. Thursday the 30th offers clean 5-foot waves with a light wind, but the period drops to 8 seconds, so it’s a bit weaker and less organised. The energy is moderate, around 630 to 670. It’s surfable, but not the star.

Then we hit a rough patch. From Friday the 31st right through to early August, the wind cranks up to 25 to 28 mph from the ENE. The swell gets bigger, hitting 8 to 10 feet, but with that strong cross-off wind and a short period of 8 seconds, it’s messy and blown out. The energy is high, in the 1000 to 1400 range, but the quality is poor. This is more of a kite-surfing setup than a clean paddle session.

There’s a gap of several days where the conditions are poor for surfing. The wind eases a bit around the 9th of August, with a Sunday afternoon session showing a 7-foot ENE swell, 8 second period, and a gentle 9 mph cross-off. The energy is 938, and it’s rated as “very good surf conditions”, but the period is short, so it’s probably a bit fat and crumbly. Still, it’s the best of a bad bunch in the second week.

Overall, if you want the best wave, you’re looking at Wednesday morning, the 29th of July. That glassy 8-foot offshore session is the one. The rest of the window is either wind-affected or too small and weak. Keep your eyes on the forecast for that Wednesday, though. It’s a real treat.

Stay salty,
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.

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.
