Table - best surf conditions forecast for Keaulanas over the next 16 days.
Alright, grab your board and listen up. Rusty here.
First off, it’s been a bit flat. There is a gap of nearly three days with nothing worth paddling out for, so we've been waiting for the ocean to wake up. Things start to turn around from Saturday morning.
Keaulanas (beach and reef) is the only game in town this period. The water temp is sitting about average for the time of year, nothing wild to report there.
We kick off Saturday morning, July 11th, with a building SSW groundswell. It’s small, around 2.0 ft, but the wind is offshore out of the ENE at 15.5 mph, which is a massive plus for clean faces. The combined energy is moderate at 325. By Saturday afternoon, the swell bumps up to 2.3 ft from the SW, still with that sweet offshore wind. Energy jumps to 414, and the wave comment turns positive. This is where it starts getting interesting. Sunday, July 12th, offers the best of the early window: morning offshore flow, 3.0 ft of SW groundswell (16 second period), and moderate energy at 376. This is the standout for the first week. Clean, lined-up waves for the intermediate crew. Crowds are possible here, so get in early.
Early next week, Monday July 13th keeps the good run going. Offshore wind, 3.0 ft SW swell, and solid energy. Tuesday and Wednesday see the energy really crank up, hitting 614 and then 708 on Wednesday afternoon, July 15th. That Wednesday afternoon session is the absolute best on offer in the whole outlook: 2.6 ft of W swell with a 15-second period, clean offshore ENE wind at 15.5 mph, and very good conditions flagged. That’s a proper session.
After that, it trickles down. Thursday and Friday still have some fun 2.0 ft to 2.3 ft waves with clean winds, but nothing that hits the same highs. Saturday and Sunday, July 18th and 19th, turn pretty average with poor conditions flagged. The swell gets a bit bigger again on Sunday the 19th, up to 3.0 ft from the S, but the wind is cross-offshore and the conditions look marginal.
The tail end of the window, July 20th through 23rd, has some small but clean surf, especially Monday morning the 20th with gentle offshore wind. It’s a mellow end to the run.
The standout: No question about it. Wednesday afternoon, July 15th at Keaulanas. The 2.6 ft W swell, 15-second period groundswell, and that sweet offshore ENE wind at 15.5 mph are going to make for some clean, fun walls. The energy is very strong at 708. This is the one to circle on the calendar.

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.
