The Lowdown
Alright, Rusty here. Let's look at what's on offer at Rockpiles.
Right off the bat, I gotta be straight with you – this outlook is a bit of a grind. We're looking at a long stretch of marginal conditions. The wave energy is mostly moderate, with readings in the 400 to 900 range, but the wind is the real problem. For the first two weeks, we've got a persistent cross-off breeze from the ENE that's just gonna keep things messy. It's clean, but it's not the kind of clean that makes for good waves.
Monday the 3rd kicks off with a 5 ft swell from the ENE, but with a short period of 8 seconds and that 15 mph cross-off wind, it's a struggle. The energy is a moderate 492, but the quality just isn't there. That same pattern holds through Tuesday, Wednesday, and Thursday – the swell drops off, the period gets weird, and it's all just average. For a spot that's exposed to a SSE optimum, this constant ENE swell is fighting it.
The whole first week is a write-off. We get a bit of a pulse on Saturday the 8th with 5 ft swell, but the period is a shocking 7 seconds. It's all wind-swell. That carries through to Sunday the 9th, with 6 ft swell and an 8-second period, but again, the wind is a strong 22 mph breeze. This is getting into the territory of being more interesting for kite surfing than a paddle session.
The second week doesn't look much better. The swell gets bigger, pushing 8 ft by Monday the 17th, but it's still that short-period ENE wind-swell. The energy is getting strong, hitting 915, but the quality is poor. This size is too big for beginners, and with the wind, it's only for the very experienced.
Now, here's the one glimmer of hope. It's a long way off, so take it with a pinch of salt, but Tuesday the 18th of August is the standout. The morning shows a glassy 7 ft ENE swell with an 8-second period, and the wind is dead calm. The energy is a strong 872. For Rockpiles, a reef break, that glassy morning is the only time in the whole 16 days where the conditions line up. It's a promise of clean, powerful surf, but it's a long way out. For a spot that's fairly consistent, this is a long dry spell, and the forecasts can change, but for now, that Tuesday morning is the only one worth circling on the calendar.
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.
