Keaulanas Surf Forecast and Surf Report

Right then folks, Rusty here with a look at what we’ve got on the cards. It’s not a huge few weeks, but there’s some real magic tucked away in the details if you know where to look.

We’re starting off slow. The first few days, honestly, are a write-off. A stormy risk of a t-storm on Sunday the 16th with a messy 16 mph cross-shore wind means you’re better off doing something else. A small 2ft S swell (346 energy) is just not worth the hassle.

But, a switch flips from Monday the 17th onwards. The energy climbs to a solid moderate level (372-300) and the wind cleans right up to a cross-offshore breeze. The swell hangs around the 2ft to 3ft mark from the South, with a long period of 14-16 seconds. This is classic groundswell behaviour – long lines, proper shape, and plenty of time between sets to paddle back out. At a spot like Keaulanas, which is a consistent beach and reef setup, that longer period will wrap in nicely, offering some proper little runners.

The real standout window is from Thursday the 20th right through to Saturday the 22nd. Thursday afternoon we see a glassy 3 mph wind out of the ESE on a 2ft SSW 17-second swell (239 energy). Then Friday morning is absolutely dead calm, glassy as a mirror, on a 2ft SW 17-second swell (312 energy). Friday afternoon and Saturday keep that glassy, calm theme going with similar small but perfectly formed SSW and SW swells. This is the pick of the entire outlook – early morning glass, clean faces, and that very long period will make every wave count. The water temp is sitting at 81°, which is about normal for this time of year, so no surprises there.

Now, for the second week, things get a bit more mixed and less certain. We see a spike in combined energy around the 26th of August – the Wednesday afternoon slot hits a strong 415 energy with a 2ft S 17-second swell and a moderate offshore wind. Clean and punchy. Then the 30th and 31st of August see energy really ramp up to very strong levels (623 and 630) with a 3ft SSW 15-second swell. The wind stays offshore (ENE to NE at 12-19 mph). These are big numbers for this spot, and while the forecasts a week and a half out have some wobble to them, the signs are there for a serious session towards the end of the run.

Final call: For the small, clean gear, don’t miss Thursday the 20th through Saturday the 22nd. For the more powerful stuff, keep your eye on the last days of August, particularly the 30th and 31st.

Rusty.
