The Lowdown
Alright, crew, Rusty here. Let's talk about the next couple of weeks. It's a slow burner, but there's a bit of a payoff if you're willing to wait.
The first part of the window is a total dud. No real surf until the 19th of August. The wind is ripping from the east-northeast at 31 mph, and the water is a warm 80°, which is pretty normal for this time of year. The little energy that's there is just wasted.
We see a little flicker of life around Thursday the 20th. The swell is tiny, just 2 ft from the southwest, and the energy is moderate (327). The wind is still cross-off, so it's not clean, but it's a start. Not worth getting wet for.
The main event is shaping up for Friday the 21st of August. The swell is still small, 2 ft from the southwest, but the period is a solid 17 seconds, which is a proper groundswell. The energy is moderate (317), and the wind is a light 9 mph. This is a classic long-period south-west swell, meaning it'll have some punch, but it might be a bit straight at the beach breaks. Think reefs and points.
The standout, the one you want to be ready for, is Sunday the 30th of August. The swell is building to 4 ft from the southwest in the afternoon, and the wind is a light 9 mph. The combined energy is strong (548), and that's a real sign of power. The period is 11 seconds, a solid, workable swell. This is the best bet we've got. The water will be warm, and the light wind means it'll be glassy. The swell direction is spot on for the break. It's a way out, so the forecast is a bit of a promise, not a guarantee, but if it holds, it's going to be a really good day.
Before that, Saturday the 29th is a warm-up, with 4 ft from the south-southwest. It's still a bit marginal, but the energy is there.
So, a slow start, a few days of "maybe," and then a real chance at a good session on the 30th. Watch the wind, and be ready to go.
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.
