The Lowdown
Hey, it’s Rusty. Let’s talk Rockpiles in feet and miles per hour.
The next couple of weeks start off rough – real rough. From Monday July 13th all the way through the rest of the month, we’ve got a dry spell. Swell’s 2 to 3 feet most days, with a steady cross-off wind from the ENE or NE at 10–20 mph. It’s clean, but the energy is weak – combined swell energy numbers sit between 280 and 581, which is low. Water temp on the 13th is 79°F, pretty average for this time of year.
There’s a little bump midweek, but don’t get your hopes up. Saturday the 18th and Sunday the 19th see the swell jump to 6–6 ft – that’s big enough for intermediates – but it’s a short-period windswell from the ENE, only 7–8 seconds between waves. Combined energy hits 525–609, but the wind’s still 20–22 mph cross-off, and the report calls it marginal. Not worth the effort.
From the 20th to the 27th, same story: small swell, moderate energy, persistent cross-off winds. The 25th and 26th mornings have a little more size – 6 to 6 ft – and combined energy in the 800–900 range, but again short period and poor conditions keep scores low. A few rain showers may appear, but they won’t save the surf.
Now for the one bright spot: Tuesday morning, July 28th. That’s the real deal. Rockpiles gets a 6 ft groundswell from the ENE with a 13-second period – long-period, powerful. Combined swell energy is 1253, strong. Wind is light, just 9 mph from the ENE, cross-off, so expect clean, glassy conditions. The direction isn’t the ideal SSE this reef prefers, but the size, period, and light wind make it an excellent session for experienced surfers. Crowds can show up sometimes, but a Tuesday morning might be your chance. This is two weeks out, so it’s promising but not locked in. Still, it’s the only standout in a long, flat stretch.
Don’t bother before the 28th. That morning is where it’s at.
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.
