Alright folks, Rusty here. Let’s size up the next 16 days for Keaulanas. We’ve got a long, slow grind ahead, but there are a couple of moments that might just get the heart rate up.

The overall pattern is tough. We’re coming off a weak, messy start with small swell and poor conditions. The water temp is sitting at 80°, which is pretty much what you’d expect for this time of year – no weird anomalies there.

The first few days, from Monday the 6th right through to Friday the 10th, are a write-off. We’re talking tiny, weak swell – mostly around 1 ft to 3 ft, with combined energy readings that are all over the place but low in the early sessions, like 128 (weak) and 151 (weak). The winds are fresh offshore or cross-offshore, so the surface is clean, but there’s just no grunt. The forecast calls it “poor surf conditions” or “marginal” for most of this stretch. Don’t bother paddling out.

Then we get a bit of a pulse. Saturday the 11th morning is still marginal, but by Saturday afternoon, we see a little jump. Swell bumps up to 2 ft from the SW with a long period of 18 seconds, and the combined energy hits 414 (moderate). The wind is offshore and moderate. It’s not huge, but that long period groundswell will wrap in nicely. For a point break, that’s a real treat. Expect clean, lined-up waves – but it’s still on the small side, so not a standout.

The best window, and I mean the *only* real standout, is Monday the 13th in the morning. Swell holds at 3 ft from the SW, period of 15 seconds, and combined energy of 403 (moderate). The wind is a gentle offshore breeze from the ENE at just 9 mph. That’s glassy, clean, and the break is consistent. For a beach-and-reef setup, this is your session. The crowd is “sometimes” an issue, so you might have a few out, but with such a specific window, it’s worth the early alarm.

After that, the second week fades out. We get a few days with moderate energy in the 400s to 500s, but the winds shift cross-offshore and the swell direction wobbles from W to SSW. The waves are clean but unremarkable – mostly 2 ft to 3 ft with periods around 14–17 seconds. It’s a long, drawn-out tail end. Nothing in the second week screams “go.”

So, to sum it up: the first week is a total dud, the standout is Monday morning the 13th with that gentle offshore wind and 3 ft SW groundswell, and then it’s a slow fade to the finish. Don’t hold your breath for the rest.

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.
