Keaulanas Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s shaping up at Keaulanas. We’ve got a 16-day window and there’s definitely some action on the cards, but we’re gonna have to be patient through a few messy days to get to the real good stuff.

The water temperature is sitting at 80°, which is about average for the time of year, so no surprises there.

The pattern starts off with some small but promising swell on Friday morning, July 17th. We’ve got a clean 2ft SSW groundswell with a very long 16-second period pushing in, and a cross-offshore breeze from the east. The wave energy is moderate (315), and it’s looking like a decent session for the intermediate crew. This is a consistent spot, but it can get a crowd sometimes, so keep that in mind. The 2ft height is small, but that long period will give it some shape.

Friday afternoon and into Saturday, the wind picks up, and the conditions get a bit sloppy. The swell stays small, but the wind gets fresh, making it a tough call. We’ll leave those sessions for the keen ones.

The real turning point hits Sunday, July 19th. The morning has a clean offshore breeze, and by the afternoon, the swell switches to a touch more south and the wind is still offshore. It’s not big, but it’s clean. The combined energy is moderate (236), and the 2ft swell is rideable.

Monday, July 20th, is when things start to get interesting. The morning is a bit marginal, but the afternoon brings a nice 3ft S swell with a 16-second period and a solid offshore wind. The wave energy jumps to 406, and it’s looking like a good session. Tuesday, July 21st, is the first real standout. The morning has a 3ft S swell, gentle offshore, and the energy is pumping at 402. It’s clean, it’s consistent, and it’s the best wave we’ve seen so far. This is a solid intermediate option.

Things get a bit odd from Wednesday, July 22nd, through to Friday, July 24th. The swell stays small, but the period becomes very long, hitting 23 to 24 seconds. That’s a very long-period groundswell, which can be a bit tricky at a beach-and-reef setup like Keaulanas. It might break a bit too straight for the beach, but if you can find the reef line, it could be interesting. The wave energy is strong (705 to 898), but the wind is mostly cross-offshore, so the conditions are mixed. It’s a marginal call, but if you’ve got a big board and patience, there might be a few.

The real standout of the whole run is the morning of Sunday, July 26th. That’s a full week away, so keep an eye on the forecasts, but it’s looking like the pick of the bunch. We’ve got a 3ft SSW swell, a clean offshore wind, and the wave energy is moderate (617). The conditions are described as “very good,” and that’s what we’re after. This is the one to circle on the calendar.

Monday, July 27th, is still solid with a 3ft swell and offshore winds, but the energy is dropping. From Tuesday, July 28th, through to Thursday, July 30th, the swell fades, and the conditions become ordinary. The wind stays light, but the waves are small and weak.

The last real highlight is Friday, July 31st. The morning is glassy with a 2ft SSW groundswell and a 16-second period. The wind is glassy, which is rare, and the wave energy is moderate (279). It’s a small, clean, and beautiful morning for a longboard or a fish. The afternoon stays glassy as well, with the energy picking up to 422. That’s a great way to end the week.

The final weekend, August 1st, is back to small conditions with a cross-offshore breeze. It’s not a write-off, but it’s not the highlight.

So, to sum it up: the best on offer is the morning of Sunday, July 26th, with a solid 3ft offshore swell, clean conditions, and good energy. The second standout is the glassy morning of Friday, July 31st, for a clean, small-wave session. Everything else is a mix of small and marginal, but there are plenty of rideable days if you’re keen.

Rusty out.
