The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Rockpiles over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start. The immediate outlook is pretty average, but don't write it off just yet. The water is sitting at a warm 81°, which is pretty much what you'd expect for this time of year, so no surprises there.

The first real glimmer of hope comes on Tuesday, the 4th of August. We’ve got some clouds overhead, a gentle cross-off breeze from the ENE at 9 mph, and a clean 5 ft swell rolling in from the ENE. The period is a solid 11 seconds, which is a proper groundswell, giving the waves some shape and punch. The combined energy is moderate at 498, so it’s not a monster, but it’s a fun, clean wave. This is the pick of the early period. Get on it.

Wednesday the 5th is a bit of a hangover from that, with a smaller 4 ft ENE swell (10-second period, 361 energy) in the morning, but it’s still clean with a gentle breeze. Afternoon drops off a bit.

After that, we hit a dry patch. From Thursday the 6th all the way through to Monday the 17th of August, the conditions are messy. The wind picks up to a fresh breeze, and while the swell sticks around, the quality is just not there. The cross-off wind is relentless, and the forecasts are all "poor" or "marginal." There’s a big, long-period SSW groundswell that shows up on the 11th and 12th, with periods over 17 seconds and energy climbing into the 800-900 range, but the wind is too strong to keep it clean. It's one to watch, but not one to paddle out for.

Now, here’s where it gets interesting. The standout, the one you’ve been waiting for, is Monday the 17th of August. The morning starts with light rain, a gentle breeze from the NE at 9 mph, and a solid 10 ft swell from the ENE. That’s a big one, with a combined energy of 1432 – that’s serious power. This is for experienced surfers only. The afternoon cleans up even more: the wind drops to a light breeze at 6 mph, the swell sits at a still-heavy 8 ft, and the energy is 1083. The conditions are excellent for those who know what they’re doing. This is the heavyweight champion of the forecast. Mark it in your calendar.

So, to sum it up: Tuesday the 4th is your best bet for a clean, fun session right now. But if you’re an experienced charger, the real gold is on Monday the 17th. Until then, the lineup’s going to be a battle with the wind. Keep your eyes on that long-range forecast – it’s a promise of something good.

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.
