Alright folks, Rusty here. Let’s have a look at what’s shaking.

Honestly, for Keaulanas, the next few days are a bit of a struggle. The swell is hanging around 3ft to 2ft from the SSW and S, but the wind is a solid 18 mph from the ENE, which is offshore and keeping things clean. The problem is the wave energy is pretty weak, sitting between 350 and 128 (moderate to weak). It’s more of a window-licker than a go-out session. We’ll see a marginal surf through Tuesday and Wednesday, but I wouldn’t get too excited.

Thursday and Friday are even smaller, with the swell dropping to 2ft and the energy bottoming out at 106 (weak). The period is short and messy for a lot of it, not giving you much to work with. The water temp here is about average for the time of year, nothing weird going on.

Now, there is a glimmer. Come Sunday the 12th, we get a proper pulse. The morning of Sunday the 12th sees the swell bumping up to 3ft from the SW with a long period of 16 seconds, and the combined energy jumps to 425 (moderate). The wind is a moderate offshore from the ENE at 12 mph. This is the standout for the first week – clean, lined-up groundswell. The afternoon gets a bit cross-off, but the morning has the goods. Monday the 13th morning is also similar: 3ft SW, 15 sec period, 343 energy, and clean offshore wind. That’s your best bet for a proper session. Keep in mind, this spot can get crowds sometimes, so get in early.

After that, we hit a bit of a flat run. From Tuesday the 14th right through to Saturday the 18th, the swell stays small, mostly 2ft to 2ft, with the wind swinging cross-off. The energy fluctuates but never really gets cooking. It’s a lull, plain and simple.

But hold onto your leash, because Sunday the 19th is the real standout for the whole 16-day window. The morning of Sunday the 19th delivers a 4ft swell from the south, with a 15 second period and a combined energy of 538 (moderate). The wind is a moderate offshore from the ENE at 12 mph. That’s clean, solid, and lined up. This is a true groundswell runner. It might be a touch big for beginners, but for intermediates and up, it’s on. The water temp is still about average.

The last real highlight is Wednesday the 22nd. The morning shows a 3ft swell from the SSW with a long period of 17 seconds, and the combined energy hits 584 (moderate). Offshore wind from the NE at 12 mph. That’s another cracking morning for a proper point-break style wave. The long period will favour the reef and point sections here at Keaulanas.

So, in short: the first few days are thin. Your two best sessions are the morning of Sunday the 12th and the morning of Sunday the 19th, with a bonus on Wednesday the 22nd. Get out there when the wind is offshore and the energy is up.

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.
