Alright folks, Rusty here. Let's have a yarn about the next couple of weeks for this stretch of coast.

Right off the bat, if you're looking for a clean, solid push of swell, you’re going to be waiting a bit. The first couple of days are pretty ordinary, with small, long-period swell and cross-off winds. It’s not until Saturday the 4th that things start to look interesting. That morning at Keaulanas, we've got a proper 2ft south swell rolling in with a very long 21-second period and offshore winds howling from the ENE at 15 mph. The wave energy is solid at 725, and the forecast is calling for very good surf conditions. That’s the standout of the whole outlook. The water temp feels about average for the time of year, so a spring suit or a shorty should be fine.

However, that long period (21 seconds) is a bit of a double-edged sword – it means great shape and power, but at a beach/reef setup it might break a little straight and be more suited to a point or reef that can handle that energy. It’s clean, and with offshore wind, it’s a must-check session. The crowd factor is "sometimes", so you might have a few out, but with that quality, it’s worth a paddle.

After that Saturday high, the swell hangs in there on Sunday the 5th with 3ft from the SSW and 18-second period, but the wind switches to cross-off, making it less perfect. The energy stays moderate at 747, but the conditions are more marginal.

From Monday the 6th through to the end of the first week and into the second, it's a real mixed bag. Swell stays between 2ft and 3ft, mostly from the south or southwest, but the wind is almost always cross-off or fresh offshore. The wave energy fluctuates, but the scores drop right off. We see a lot of "poor surf conditions" or "marginal surf" labels in the data. There's nothing that screams "drop everything and go" again.

The second week is quiet. There’s a little bump of energy around July 10th with a 1ft swell but a very long 21-second period from the SW, giving a moderate 206 energy, and offshore wind – that’s a little glimpse of something, but tiny. Saturday the 11th has some 2ft SSW swell and offshore wind again, but the combined energy at 328 is only moderate.

Honestly, if you’re planning a surf trip, focus on that Saturday the 4th morning. The window of quality is narrow, and everything else is pretty average with steady cross-off winds and small swell. If the wind were lighter and more offshore for the second week, that would be a different story, but as it stands, Saturday the 4th is your best bet.

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.
