The Lowdown

Right, grab a coffee, this is a bit of a mixed bag.

Alright, let’s talk about Rockpiles. This is a fairly consistent reef break, but we’re looking at a long stretch of challenging conditions. The wind is going to be a major factor over the next 16 days, mostly blowing hard from the ENE, which is cross-off here. The swell is there, but it’s often messy or too raw.

We start off with a bit of a pulse on Tuesday, July 28th, with a solid 7ft to 8ft easterly swell, but the wind is a moderate breeze at 15 mph. It’s a cross-off, so the surface will be clean, but the energy is strong (1820 to 2120). That second afternoon session is a little too big for beginners at over 8ft. The water temp is about average for the time of year.

The following days are a write-off. Wednesday, July 29th, sees a tiny 2ft south swell with onshore wind – just flat and choppy. Thursday the 30th has a short-period 5ft easterly, but it’s not clean. Friday the 31st through to the end of the first week is a real grind. The wind howls from the ENE at 25 to 31 mph, and we’re looking at 6ft to 8ft of short-period, wind-affected swell. The energy is there (807 to 1314), but it’s just not surfable for a proper paddle session. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

The second week doesn’t bring much joy. From Monday, August 3rd, through to Sunday, August 9th, it’s a constant diet of cross-off winds from the ENE, mostly fresh to strong breeze. The swell hangs around 5ft to 8ft, but the period is short, and the scores are all low. The energy is moderate to strong, but the quality is just not there. It’s a long stretch of poor to marginal surf.

There is a tiny flicker of hope on the very tail end of the forecast. On Monday, August 10th, and Tuesday, August 11th, the swell drops right down to 3ft to 4ft, but it switches to a long-period groundswell from the SSW and S, with periods of 14 to 16 seconds. This is a very long-period swell, which is best for this reef, and the offshore wind is from the ENE. The energy is still moderate (476 to 785), but the combination of long period and clean cross-off wind could make for some surprisingly fun, glassy waves. It’s the only real standout in the whole run, but it’s a long way off, so keep an eye on it.

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.
