The Lowdown
Alright, Rusty here. Let's break down what’s in store for Rockpiles.
Honestly, the start of this stretch is a letdown. The wind's hanging tough from the ENE, keeping the surface clean with a cross-off blow, but the swell is weak and short-period. For the first few days, we're looking at small, gutless waves with the energy readings barely scraping 500. It's a classic case of "don't bother" unless you need the exercise paddling. There's a real gap here for quality surf.
The first time it gets interesting is on Tuesday, August 4th. The swell picks up a bit of length, hitting 11 seconds from the ENE, and the wind finally backs off to a gentle breeze. The wave heights are around 4 to 5 feet, and that combined energy sits at a moderate 596. That lighter wind and longer period are going to make a huge difference – cleaner, better-shaped waves. That's our standout.
After the 4th, the window closes again. The swell period drops back to the 7-8 second range and the wind cranks back up to a fresh to strong breeze. It gets messy. We see a little spike from the SSW around the 10th, but at just over 2 feet with a fresh breeze, it's not going to do much here.
Looking further out to the 12th and 13th of August, we've got some S swell showing up with really long periods – 16 to 18 seconds – and the energy climbs into the 700s and even 900s. The wave heights stay small, around 3 to 4 feet, but that long-period south energy could push in nicely. The problem is the wind stays on it from the ENE at 20-25 mph, which will keep the surface lumpy. It's a long-range hope, not a guarantee.
So, the pick of the entire 16-day run is the 4th. The rest is mostly a waiting game. Don't write it off completely, but don't hold your breath either.
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.
Rockpiles is 4 km (2 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
