Keaulanas Surf Forecast and Surf Report

Alright, this is Rusty checking in with a look at what’s coming up for Keaulanas. This spot is a consistent beach and reef break that’s exposed to the swell, and it’s got a real affinity for west swell direction. The water temperature is sitting at 81°F with a small positive anomaly, so it’s a touch warmer than average for this time of year – not a big deal, but you might notice it feels a bit more tropical than usual.

Right now, things are pretty quiet. The first real suggestion of surfable waves doesn’t show up until Friday, August 14th, and even then it’s marginal. You’re looking at a 4ft south swell with a 14-second period, and the wind is offshore from the ENE at 15 mph. The combined swell energy is moderate at 520. It’s clean, but the comment warns about questionable tide conditions, so it’s not a standout. After that, the next few days drop off significantly. The swell fades to 3ft and below, and the wind picks up to strong offshore breezes up to 28 mph, which makes it hard to paddle into. The energy drops into the 200-300 range, and the overall vibe is poor surf. You’re looking at a gap of several days where there’s really nothing worth chasing.

The first real standout for me comes later in the window. On Wednesday, August 20th, the morning shows a 2ft southwest swell, but the period stretches out to 18 seconds – that’s a long-period groundswell, which usually means better shaped waves and more energy. The combined swell energy is moderate at 376. The wind is light offshore from the ENE at 6 mph, so conditions will be clean. It’s a promising option, but it’s still a week away, so I’d keep an eye on it.

The real highlight of the whole 16-day run is shaping up for Wednesday, August 26th, and Thursday, August 27th. On Wednesday afternoon, you’ve got a 2ft south swell with a 17-second period, and the wind is offshore from the ENE at 15 mph. The combined swell energy jumps to 647 – that’s strong energy. This is rated as very good surf. Then Thursday morning keeps it going: 3ft from the SSW at 16 seconds, light east wind at 6 mph, and combined energy of 654. That’s the strongest energy in the whole forecast. The period is long enough to really push the sets through, and the light offshore wind will keep it glassy. This is the one to circle on your calendar. Just remember, it’s deep in the second week, so treat it as promising but not locked in.

After that, the end of the window fades into smaller glassy conditions with long-period swells, but nothing that matches that midweek energy burst. So, overall, there’s a slow start, a decent mid-range option on the 20th, and a solid peak right around the 26th and 27th. Keep your expectations measured for the first half, but get excited for that final push.
