The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
Right off the bat, the forecast for Pipeline (Oahu) is a bit of a tease. We’ve got a solid pulse of energy arriving on Tuesday, but the wind and conditions are going to keep things from being anything close to perfect. The combo of an 12ft southwest swell and a 30 km/h cross-off wind is going to create some serious juice, but that cross-off breeze will have things lumpy and hard to manage. The energy is strong – you’re looking at a combined swell energy of 2453 – but the quality just isn’t there. This is advanced territory only, and even then, it’s going to be a battle. The water is a warm 80°, which is pretty average for this time of year.
The next couple of days, Wednesday and Thursday, see that big swell back off in a hurry. We’re dropping to under 3ft, but the period jumps up nicely. Wednesday morning has some really clean lines with a 3ft SSW groundswell at a solid 14 seconds. The wind is light and offshore, so it’s going to be glassy and smooth. This might be the most user-friendly window of the whole forecast if you can find the right bank. After that, Thursday is smaller, but that 18-second period on Thursday afternoon is something else. That’s some seriously long-period energy, the kind that wraps and holds its shape, but it might be breaking a bit straight on a beach break like this. You’ll need to be on your toes and pick your waves carefully.
From Friday through the following Thursday, it’s a slow grind. The swell stays small, bumping between 2ft and 3ft, with long periods but not much push. The winds are consistently cross-off from the east-northeast, which keeps the surface clean, but the energy is weak, with combined values dropping into the low hundreds – that’s just not enough for a hollow wave like this to really fire. It's a waiting game. You’ll get the occasional fun one, but there’s nothing that’s going to have you paddling out with your heart pounding. It stays like this for a while, a good week or more of small surf.
Then, looking ahead to the 23rd of September, the tail end of the forecast shows a small bump in period back to 17 seconds, but the swell size is still just 2ft. It’s promising in the sense that the ocean is alive, but for Pipeline, that’s just not going to cut it. Long story short, if you want the best chance at a proper session, Wednesday morning is your best bet. It won’t be the biggest, but the conditions will make it the most rideable. The big stuff on Tuesday is for the brave and the crazy, and even then, it’ll be messy.
Rusty out.

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.
