Alright, Rusty here. Let’s take a look at what’s on offer for this stretch of coast.
Honestly, I’m looking at a pretty grim 16-day outlook. There’s barely a decent wave in sight. The whole run is plagued by strong cross-off winds, mostly from the ENE at 18 to 25 mph, which just tears the surface apart. The swell is all over the place but never comes together for a proper surf. The first few days are the closest we get to anything, and even then it’s a struggle.
We kick off on Friday the 3rd of July with a 5 foot swell from the ENE, but the period is a short 8 seconds – that’s windswell, not groundswell. The combined energy is moderate (519 in the morning, 550 in the afternoon), but the 18-22 mph cross-off wind is strong enough to make it feel messy and hard to hold your line. Not really worth paddling out for.
Saturday the 4th of July starts similar in the morning, 6 foot from the ENE, but the afternoon throws a curveball – a 2 foot groundswell from the S with a 20-second period rolls in. That long period is packed with energy (898), but the direction is mismatched for the optimum swell direction, and the wind is still howling. The wave quality suffers; it’s not going to shape up cleanly. The combined energy is moderate, but the conditions just kill any real potential.
From Sunday the 5th of July onward, it’s a slow slide into nothing. The swell stays below 3 foot, mixed between SSW and SW, with longer periods but no size. The energy values drop quickly – we’re looking at 792 on Sunday, then 767 on Monday, and by the 10th of July it’s down to 320. The winds never let up. For the rest of the window, into the second week and right up to the 18th of July, every afternoon and morning is marked poor. The combined energy is weak to moderate at best, and really, this setup looks more interesting for kite surfing than paddle surfing – the wind is consistent, but the waves are not.
In a nutshell: there’s no standout day here. No moment where it all clicks. The whole 16-day stretch is one long, unfortunate gap for quality surf. It happens sometimes in this area, when the trade winds blow hard and the swell doesn’t line up. Forecasts can change, but as it stands, leave the board at home.

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.
