Alright, Rusty here again, giving you the same rundown in feet and miles per hour.
Look, I’m gonna level with ya – it’s a rough stretch ahead. The next couple weeks are a real mixed bag, and honestly, the surf quality is struggling. The predominant wind is a fresh cross-offshore from the ENE, which sounds good in theory, but the swell is just not cooperating. The water temps are running about average for this time of year, so no surprises there, but you’ll want a spring suit.
The first few days, starting Saturday the 4th, offer a small window but it’s marginal. Saturday morning shows a 6 ft swell from the ENE, but it’s short-period stuff at 8 seconds, not much grunt. The energy is moderate (899). By Sunday the 5th, it drops right off to 3 ft, and the models are calling it poor – I’d say give it a miss.
Monday the 6th sees a bump in size, up to 7 ft to 7 ft from the ENE, but the period is still a weak 7 seconds. That’s a lot of lumpy, close-out shorebreak with 22 mph winds. The combined energy is moderate (818-961), but the wave comment is “poor surf.” This is getting into kite-surf territory more than paddle surfing, if you ask me.
From Tuesday the 7th right through to the end of the 16-day window on Sunday the 19th, it’s a long, grim run. Swell heights bounce between 2 ft and 8 ft, but the period stays under 8 seconds for most of it, and the wind never lets up. The energy drops from moderate down to weak, and almost every single session is rated as “poor surf conditions.”
There are a few brief flickers of hope around the 12th and 13th of July, where we get a groundswell from the SW at 15-16 seconds, but it’s only a 3 ft. The energy is still moderate (520-648), but those long-period swells at a reef like Rockpiles can sometimes line up nicely. The wind is still a cross-off 16 mph, so it’s not glassy, but it’s the cleanest looking surf in the whole outlook. That’s your best bet, but keep expectations low.
Honestly, if you’re not desperate for a paddle, the setup looks more interesting for kite surfing than paddle surfing for most of this period. The consistent wind and bumpy swell are not our friends. Crowds are possible here, but with this forecast, you’ll likely have the place to yourself.
This is Rusty, signing off.

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.
