The Lowdown

Alright, this is Rusty. Let’s break down what’s happening at Pipeline.

I’m not gonna sugarcoat it – this 16-day forecast is a grind. There’s one sweet, clean window right at the start, and then the trades come in and don't let up. From the 22nd of August all the way through the 3rd of September, it’s mostly a bust. That’s nearly two weeks of windy, poor surf. You gotta be patient and pick your moments. The one true standout is that first morning.

Friday morning, the 21st of August, is your golden ticket. We’ve got a clean 2ft swell out of the SW with a deep 17-second period – that’s real long-period groundswell. At a reef like Pipe, that long period makes it stand up tall and throw hard. The wind is light and easterly at 6 mph, keeping the surface glassy. The combined energy is solid at 354 (moderate wave energy), and it’s consistent. It’s an exposed spot, so it’s catching all the energy. Just know that crowds are often here, so expect some company.

The afternoon stays clean but the swell drops off a little. Then from Saturday the 22nd, the wind jumps to 19 mph from the ENE, and it just stays howling for days. It’s cross-off, so it’s not totally dead, but with wind that fresh (forecast scores of 0 out of 10), it’s going to be messy and hard to surf.

We finally get a change on Thursday afternoon, the 3rd of September. The swell jumps to 6ft from the NNE with a 10-second period. That’s a lot of power, with combined energy of 576 (strong wave energy), but the report says it’s marginal due to tides. That size is for experts only. It’s not a standout, but it’s the only thing worth looking at in the second week.

After that, it fades back to small and weak. The morning of the 5th of September has a 2ft SSW groundswell with a 19-second period – super long period. That will barrel at Pipe, but the sets will be few and far between with low energy (246, moderate wave energy). With a moderate breeze, it’s a "maybe" session at best.

So here’s the plan: surf the hell out of Friday morning the 21st. Then you’ve got a long wait until the 3rd of September, which offers a powerful, tricky session for the experts. Keep checking the forecast, things can change.

Rusty.

Information about the Pipeline Surf forecast

The above surf forecast table for Pipeline provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Pipeline can be found by selecting the local surf guide option on the grey menu. Our Pipeline 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 (Pipeline) 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 Pipeline 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.

Pipeline is 19 km (12 miles) from Wahiawa. If you plan a vacation in Oahu, look for hotels and other accommodation in Wahiawa. Wahiawa has rooms for a wide range of budgets as well as car hire and transport links.
