Alright, Rusty here again. Let’s talk Keaulanas in feet and miles an hour.
Right now, this spot is on life support. For close to a week and a half, there is barely a wave worth paddling for. Tiny surf, cross-off winds every day, and a whole lot of frustration. The combined swell energy stays weak to moderate through the first week—like 115 to 700—but the conditions are poor to marginal almost constantly. You’re looking at a long dry spell until around Monday the 21st of July.
The early action, like Friday the 10th and Saturday the 11th, offers a tiny 2ft to 2ft S/SSW swell. Offshore winds from the ENE at 15 to 18 mph keep things clean, but that’s about it. Not enough to get excited about.
The first real glimmer comes Tuesday morning, July 22nd. Light ESE breeze at 6 mph, glassy conditions. Swell is about 2ft from the S at 13 seconds—good period. Combined swell energy hits 281 (moderate). It’s small but clean, and if you’re desperate it’ll put a smile on your face.
But the standout is Saturday morning, July 25th. Gentle offshore NE wind at 9 mph, clean as glass. Swell is 3ft from the SSW, period 16 seconds—proper groundswell with some grunt. Combined energy is 660 (moderate to strong). On this reef and beach setup, that long period swell will line up really nicely. Crowds are possible sometimes, so expect a few folks around if the word gets out. Water temp is 80°, pretty much normal for this time of year.
Don’t bother paddling out before the 22nd—you’ll just get wet and annoyed. But that last weekend is the real deal.
Rusty out.

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.
