Alright, Rusty here. Let's break down what’s coming.
So, we’re looking at Rockpiles. This is a reef break for the advanced crew only. Don’t even think about it if you’re not ready for a heavy wave.
It starts up on Tuesday, July 7th, but it’s a rough kick-off. We’ve got a strong cross-offshore wind blasting all day, and the swell is a messy 7 ft from the ENE with a weak, short period of 7-8 seconds. The combined energy is moderate (963), but the quality is totally out the window. This looks more like a kite surfing setup than a paddle one. No real recommendation for the first several days.
This rough stretch holds through the whole first week. From Wednesday the 8th all the way to Monday the 13th, the wind stays a stiff cross-off, the swell hangs in the 6 ft to 7 ft range with that same short period. The wave energy is moderate (between 487 and 885), and the forecast keeps saying “poor surf conditions.” Nothing to get worked up about.
Now, the real highlight comes in the second week. Lock in Sunday the 19th and Monday the 20th of July. On Sunday, the combined energy jumps into strong territory (1063), with the swell holding at a solid 8 ft from the ENE. The period is still a bit short at 8 seconds, but we’re seeing a score of 2 in the forecast, which is the best on offer. Monday edges it up to 8 ft with the energy peaking at 1113. That’s getting into the expert-only zone. The wind is still a cross-off, so it won't be glassy, but it's the best looking window.
The water temp is around 80° with an average anomaly, so it's normal for the time of year.
Crowds can pop up here, so expect some company if the swell gets good.
So, the standout is Sunday the 19th and Monday the 20th of July. Solid swell from the ENE, and the energy is finally pumping. It’s a long way out, but that’s the one to watch.
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.
