Alright crew, Rusty here again, but in feet this time.

Looking at Rockpiles for the next couple of weeks, and I’ll be straight with you – it’s not looking pretty. There’s a rough start and a long, flat feeling through the whole run.

First up, the water temp is 79°F, just a hair above normal for this time of year, nothing to worry about.

Okay, from Thursday July 2nd through Saturday July 4th, there’s some small waves but the reports are all "marginal" or "poor". The wind is a fresh cross-off from the ENE at 18 to 22 mph, which isn't what we want. The swell is small, from the ENE, with a short period of 8 seconds – that’s just messy windswell. The combined energy is moderate (517-865), but conditions are junk. Honestly, this stretch might be better for kiteboarding than paddling out.

Then there’s the one real tease. On Saturday July 4th and into Sunday July 5th, a long-period groundswell from the S/SSW sneaks in with periods of 18 to 21 seconds. The height is tiny – only 2ft to 3ft – but the combined energy is huge for that size (781-946). That’s a proper slug of juice. Now, Rockpiles is a reef, and reefs love long-period groundswells, so the wave shape could be fun. The catch? Wind is still fresh from the ENE at 18 to 25 mph. It’s cross-off, not properly offshore. So you’ve got a powerful little pulse, but the surface is going to be chopped. If you can get out on the Saturday morning or Sunday morning of July 4th/5th, that’s your window. Crowds are “sometimes” a factor here, so you might have a few mates.

After that, from Monday July 6th onward, it’s a long, bleak stretch. We get back to ENE windswell with short periods of 7 seconds, fresh cross-off wind, and poor to marginal conditions. The surf is 5ft to 7ft from the ENE, but it’s just fat, weak, and blown out. There’s a whole week of this slop, right through to Friday July 17th, when the energy finally drops off. Nothing in the second week looks worth paddling out for.

Alright, so the call is simple. The only flicker of life is that S/SSW groundswell on the 4th and 5th of July, but even that gets messed up by the wind. Everything else is just short period junk in a fresh breeze. If you’re a glass-half-full surfer, take a look at that Saturday morning reef session, but don’t expect perfection. For the rest of the 16 days… it’s a write-off. A lot of the second week is pure poor conditions.

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.
