Kahalu'u Beach Park Surf Forecast and Surf Report

Alright folks, Rusty here. Let's talk surf for your local waters.

We’re kicking off with a bit of a slow start, but there’s some decent Southern Hemi groundswell energy on the way, especially later in the run. The water’s sitting at a warm 82°, which is a little over a degree warmer than average for this time of year, so it’s gonna feel nice.

For the first week, it’s pretty marginal. The first real chance to get wet is from Thursday the 13th afternoon. That’s when we see a window of opportunity at Kahalu'u Beach Park (Kona) . Around midday on Thursday the 13th, the wind is set to go dead calm—glassy conditions with a solid 4ft SSW groundswell rolling in with a period of 15 seconds. That’s a long-period, clean groundswell bringing moderate to strong wave energy (707). For a beginner-friendly reef break, this is about as good as it gets for a quick session. The swell is small enough to be manageable, and the calm air will make it silky. Just keep in mind it gets crowded here sometimes.

Thursday the 13th afternoon is the standout for the first week. After that, the surf holds around the 3ft mark through Friday the 14th with glassy conditions in the afternoon, but the energy drops a bit (456). The weekend gets a little smaller, and by Sunday the 16th, it gets messy with onshore winds and even a risk of thunderstorms—not worth it.

That long-period swell is a groundswell, so at a reef break like Kahalu'u it should set up nicely, but just be aware that with a 15-second period, the sets will be a little more spread out.

Things go quiet again from around Monday the 18th through to Friday the 22nd. That’s a solid five-day stretch of poor to marginal conditions, tiny surf and mostly cross-on winds. It’s a bit of a dead period, so don’t expect much.

Now, the second week starts to look more promising. The best bet of the entire outlook looks like it could be Tuesday the 25th. The afternoon session at Kahalu'u Beach Park is looking proper: glassy winds, a clean 4ft SSW swell still with that nice 15-second period, and the combined wave energy jumps back up to strong (801). That’s expert-friendly size, but for a beginner reef break at 4ft, it’s still very surfable for a wide range of folks if you’re confident. This is the one to circle on the calendar—Tuesday the 25th afternoon. It’s a long way out, so keep an eye on it, but it’s got that “very good surf conditions” feel to it.

Following that, Wednesday the 26th holds some 3ft swell with a very long 18-second period, but it’s onshore winds all day, so it won’t be as clean.

All in all, we’ve got a small window late this week, a dry spell, and then a proper shot of good conditions around the 25th. Stick with it.

Rusty.
