Alright, Rusty here. Let’s have a look at what’s cookin’ at Rockpiles.

Honestly, it’s a tough stretch ahead. For the entire 16-day window, we’re looking at persistent cross-offshore winds from the ENE and a swell that’s coming from the same direction, which is almost exactly the opposite of what this reef setup wants. The swell is mostly short-period stuff around 7-8 seconds, and while there’s moderate wave energy in the mix – with combined energy readings mostly sitting between 357 and 918 – the quality just isn’t there. The water temp feels about average for this time of year, so no surprises there.

From Monday the 6th right through to Sunday the 12th, it’s a write-off – scores are poor, and the conditions are just ugly for a proper surf. We’re talking 5ft to 7ft of short, crumbly ENE swell getting battered by 22 to 25 mph cross-off winds. That’s messy, blowy, and hard to enjoy. For a break that’s fairly consistent and exposed, this is a frustrating stretch.

There’s a glimmer on Monday the 13th and Tuesday the 14th, but it’s marginal at best. The swell drops right down on Tuesday morning to 3ft from the SSW with a much longer 14-second period, and combined energy hits 602. That’s a groundswell pulse with better shape, but the wind is still a fresh cross-off from the ENE, so it’s not clean. On Wednesday the 15th, we get a tiny 2ft SSW pulse with an 18-second period – very long period for this spot – combined energy around 530. That’s a promising wave for the reef structure, but there’s almost no size to work with.

The last few days from the 16th to the 21st are more of the same – building ENE windswell back up to 6ft, but with those same cross-off winds and short periods. There’s a slight improvement on Tuesday the 21st morning when the wind drops to 16 mph and the score ticks up to a 2, but it’s still marginal.

So, what’s the standout? Honestly, the only window worth keeping an eye on is Wednesday the 15th. If you grab that 2ft SSW groundswell at dawn, before the wind gets too much on it, you might find a clean, lined-up reef wave with serious glide from that 18-second period. It’s tiny, but it could be glassy and fun for a log or a single-fin. The rest of the period? I’d maybe take the kite out instead.

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.
