The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for this stretch.
Honestly, we’re looking at a pretty long, flat spell to kick things off. The first real surf that’s worth paddling out for doesn’t show up until the morning of Tuesday the 18th of August. Before that, we’ve got days of tiny, weak, and messy waves with scores that are just not worth the paddle. That’s a solid week of nothing doing.
Tuesday, August 11 through Monday, August 17 is a write-off. Swell heights are almost all below 3 ft, with periods that are all over the place, and mostly cross-off winds that aren't helping the shape. There’s some very clean offshore wind on Monday the 17th, but the waves are just too small at 1.0 ft to do anything with.
The real glimmer of hope starts on Tuesday, August 18th. The morning shows a little pulse of 1 ft SSW swell with a period of 17 seconds. That's some long-period groundswell energy and the combined swell energy is 113 (moderate). The wind is a gentle offshore breeze from the ESE. That means clean conditions. You'll want a point break or reef for this one, as long-period swells can straighten out on a beach. The water temp is sitting about average for this time of year, around 59° to 59°F, nothing unusual.
The morning on Tuesday, August 18th at Pipeline is the standout of the whole outlook. It’s the only time where the score and conditions come close to lining up. But keep an eye on the crowds – Pipeline is *often* packed, so you’ll have company.
The rest of that week into the weekend sees slightly more size, but the winds stay cross-off. Things get a bit more interesting on the morning of Sunday, August 23rd. Swell bumps to 4 ft from the SSW, period holds at 15 seconds, with a strong combined energy of 575 (strong). Winds are still cross-off from the east though. It’s cleaner than most, but it’s not glassy.
After that, we tail off again into flatness by Tuesday the 25th. So overall, if you’re itching for a wave, mark your calendar for the morning of the 18th. It’s not huge, but with that long period and clean glass, it’ll be your best shot.
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.
