Alright folks, Rusty here. Let's have a look at what Rockpiles has got cooking for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week is a real mixed bag. The forecast shows a consistent cross-off wind from the ENE, which is usually a good thing for this spot, but the real problem is the swell. It’s coming from the ENE too, with short periods (7-8 seconds) and poor surf conditions are the story. The energy is moderate but messy, with values around 574-888 (moderate energy). We're looking at waist to head-high stuff, around 6ft to 8ft, but it's just not letting it set up. That's a lot of grunt but no form. Water temp is sitting at a pretty warm 80°, which is about average for this time of year.

Things don’t really get interesting until the 12th of July, Sunday morning. The swell flips to a long-period SW groundswell of 16 seconds, but it’s only 3ft. Still, that period is a real tease. Later Sunday afternoon, we go back to the short-period ENE stuff, and it’s still only *marginal*.

There’s a glimmer of hope around the 17th of July, Friday afternoon. The wind drops to a gentle breeze, and we get a tiny 2ft SSW groundswell with a 16-second period. The report actually says "expect good surf conditions," which is a standout in this otherwise bleak run. It'll be small and clean, but for this spot, that’s the best offer.

Then, look at the 20th and 21st of July. We’ve got a proper groundswell rolling in from the east (16 to 19 seconds) with moderate energy (values around 583-758). The swell is small though, 2ft to 3ft. The long period means it's a groundswell, but for a reef setup like Rockpiles, that long period could actually make it break a bit too straight across the reef bar. It’s definitely not for beginners, and the reports are still calling it marginal. The wind is a moderate cross-off, so the surface should be clean.

The best bet in the whole window is that Friday afternoon on the 17th. It’s the only time the forecast says conditions will be "good." It’ll be tiny and clean, with gentle winds. For the rest of it? You’re mostly waiting. Don't get your hopes up for anything over chest-high that actually has a proper shape until that last weekend.

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.
