The Lowdown
Alright, lemme break it down for ya in the old numbers. This is all about Pipeline.
First off, we gotta sit through a dry spell. From Friday the 14th through to about Tuesday the 19th, it’s almost nothing – wave heights barely a foot or two, and the energy readings are weak (as low as 4). Wind’s blowin' cross-off, but on waves that small, you're just bobbin' around. Don't bother paddling out.
Things start to turn on Thursday the 20th. We see some small pulses of SW groundswell around 2ft, but the energy is still moderate (258 max) and the call is marginal. The first real bright spot hits on Friday the 21st. That morning and afternoon, we get a clean 2ft swell from the SW with a super long 17-second period, and a light breeze from the east at 6 mph. The energy climbs to 355. That’s the first good chance for some clean, lined-up waves at Pipe. The long period will help the shape, but at that size, it’s still soft.
Saturday the 22nd afternoon is another standout. The wind turns light offshore from the ESE at 9 mph, giving us glassy conditions. Swell holds around 3ft from the SSW with a 16-second period and moderate energy (318). That's clean and groomed on the reef – a proper little window. Just know, the crowd factor is high here. There’s always a few guys out.
Then we hit a bit of a lull, but Tuesday the 25th and Wednesday the 26th push the energy up a notch (higher readings around 499) with a 3ft swell from the SSW, period down to 14 seconds. Wind is cross-off, and the surf is called marginal. Not the best, but the energy is there.
The rest of the run fades out after the 27th with tiny, weak surf. The clear winners are Friday the 21st and Saturday the 22nd – small but clean, with that long-period groundswell and light winds. Water temp is about 80°, which is pretty normal for this time of year.

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.
