The Lowdown
Alright folks, Rusty here. Let’s check out what’s on the menu for Keaulanas. We’ve got a solid run of small but clean, rideable surf stretching across the next couple of weeks. The water is sitting at 80°F, which is pretty much average for this time of year, so no surprises there.
The real story is the wind. For the first week and a half, we’re seeing a lot of offshore and cross-off breezes, which will keep the surface glassy or clean. The swell is coming mainly from the SSW, with a period that starts long and drops off slowly. That long-period groundswell (up to 24 seconds at the start) means the waves will have good shape and energy, but at a beach-and-reef setup like Keaulanas, it can be a bit straight. Still, the moderate energy (combined energy around 405 to 714 for the first few days) keeps things interesting.
The best on offer? Wednesday the 22nd and Wednesday the 29th of July are standouts. On the 22nd, Wednesday afternoon sees a clean 2ft SSW swell with a 23-second period and a solid offshore breeze from the ENE. The energy is strong (629) and conditions are set to be excellent. Then on the 29th, Wednesday morning and afternoon both have 2ft SSW swell, light offshore winds, and clean, glassy conditions. That’s a sweet spot.
Thursday the 30th of July morning is also a banger—glassy conditions with a 2ft WSW swell, period of 13 seconds (334 energy). That’s a real treat, with the wind so light it’s glassy. Friday the 31st of July morning repeats that glassy magic with a 3ft W swell and 14-second period (410 energy). The afternoon of the 31st is even better with a 3ft W swell, 13-second period, and gentle offshore wind (637 energy). That’s a top session.
Now, after the first week of August, the winds start to get a bit stronger and the swell drops off a little. The 1st and 2nd of August are a write-off—poor conditions with strong cross-off winds. But from the 3rd of August onward, things tidy up again with smaller 2ft to 2ft swells, good offshore winds, and even some glassy mornings. The 4th and 5th of August both have glassy starts with 2ft SSW swell and 16-second period, perfect for a longboard or a fun fish.
Overall, Keaulanas is a consistent spot through this period. The crowds can be around sometimes, but with these clean, small waves, it’s not going to be a zoo. The SSW swell direction is a good match for the break’s optimum from the west, so the waves will have some punch.
Keep an eye on that Wednesday the 22nd and the end of the month—those are the real gems. The long-range stuff (first week of August) is promising but a bit less certain, so don’t bank on it.
Rusty.

Information about the Keaulanas Surf forecast
The above surf forecast table for Keaulanas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Keaulanas can be found by selecting the local surf guide option on the grey menu. Our Keaulanas 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 (Keaulanas) 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 Keaulanas 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.
Keaulanas is 7 km (4 miles) from Makakilo City. If you plan a vacation in Oahu, look for hotels and other accommodation in Makakilo City. Makakilo City has rooms for a wide range of budgets as well as car hire and transport links.
