Alright, Rusty here. Let’s talk about what Rockpiles has on offer. We’ve got a bit of a wait on our hands, I won’t lie. For the first few days, from Sunday the 5th right through to Saturday the 11th of July, the surf is there in size but the quality is just not happening. The wind is a persistent cross-off from the ENE, blowing at 19 to 25 mph, and while the waves are clean in appearance, the conditions are rated as poor. The swell is coming from the wrong direction too – ENE instead of the optimum SSE – and the period is short, around 7 to 8 seconds, so it’s not offering much shape or power at this reef. The combined energy is moderate to strong though, hitting between 378 and 976 on various days, which says there’s plenty of water moving.
Then there’s a shift from Sunday the 12th of July. We get a string of days through to Tuesday the 14th where the surf is still only marginal – the tide or something else is making it tricky. The swell hangs around 5 ft to 6 ft from the ENE, still a short 7 to 8 second period, and the wind stays cross-off at 16 to 19 mph. It’s not terrible, but it’s not firing. The energy dips a bit here, from 814 down to 532.
Come Wednesday the 15th, the swell drops right off. We’re looking at 3 ft on Wednesday morning with only 90 wave energy – weak stuff. The afternoon picks up a little to 5 ft but it’s still poor. Thursday the 16th through to Monday the 20th sees a bit more size, 5 ft to 7 ft, but it’s the same story: wrong swell direction, short period, stiff cross-off wind. A couple of spots are rated marginal, but nothing that gets the heart racing.
So honestly, there’s no standout in this 16-day window for Rockpiles. The best you could hope for is those marginal days from the 12th to the 14th when the swell is at least around 6 ft to 6 ft, and the wind is a touch lighter at 16 to 19 mph. But even then, with the swell coming from the ENE instead of the preferred SSE, and a short period of 7 to 8 seconds, it’s not going to be the kind of reef session you’d write home about. It’s a fairly consistent spot, so a blank run like this is a bit unusual, but forecasts can change. Keep an eye on it.
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.
