Alright folks, it’s Rusty here.

Well, looking over the next couple of weeks, the first few days are pretty quiet. Sunday morning the 5th kicks off with a small 3ft SSW groundswell with a very long 18-second period. The combined energy (747) is moderate, not weak, but the wind is a moderate 16 mph cross-off breeze from the ENE, keeping things clean enough. Still, it’s only marginal, not a standout. The water temp is 80°, about average for this time of year, so a normal summer feel.

Sunday afternoon the 5th turns proper offshore with 19 mph winds, same 3ft SSW swell, but still just marginal. Monday the 6th and Tuesday the 7th are a bit bigger in swell energy but drop in period and the scores reflect it being poor or marginal.

Then we hit a real dry spell. From Wednesday the 8th right through to the 11th, it’s a run of poor surf conditions with combined energy dropping into the double digits and low 100s. Swell stays below 3ft and the period drops right off. Just not worth paddling out.

Things start to look up on Sunday the 12th. The 3ft SW swell is back up to a solid 16-second period, combined energy is moderate at 376, and we get a moderate offshore breeze from the ENE at 16 mph. It’s offering the best conditions of the early period, but still only a marginal shout at best.

The real standout, and I mean the one to circle on the calendar, is Thursday the 16th. Wednesday the 15th builds with a 3ft W swell and 16-second period, combined energy up over 700, but it’s Thursday morning that conditions peak perfectly. We’ve got a 3ft W groundswell, a very long 15-second period, combined energy at 569 (moderate), and here’s the kicker – glassy conditions. Zero wind. It’ll be dead clean. This is the best on offer for the whole outlook. The swell direction is W and that lines up with what the spot likes, making for clean, shapely waves at the Keaulanas break. It’s a consistent spot, though crowds are _sometimes_ an issue, so get there early.

Friday the 17th morning is still glassy, but the swell has backed off to 2ft, and energy is down. Still good, but not the peak.

The final week fades out with small residual swells of 1ft to 2ft and moderate offshore winds, but nothing that’ll get the heart racing.

So, if you’ve got a window, Thursday the 16th morning at Keaulanas is the pick. No contest.

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.
