Kailua Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Kailua Beach.

Right off the bat, I gotta be straight with you – this stretch looks pretty grim for paddling. The next couple of weeks are dominated by onshore trade winds, mostly from the ENE, and they’re blowing hard. The swell is coming from the same direction the wind is coming from, which is a recipe for chopped-up, messy surf. The combined energy is moderate at best, sitting around (173) on Saturday morning and climbing up to the (200-300) range over the next few days, but it doesn’t matter when the wind is ruining it. The water temp is a balmy 80°F, which is about average for this time of year.

We’ve got a long, bleak run here. From Saturday the 8th all the way through to Thursday the 20th of August, every single session is rated as poor. The swell gets bigger, but the wind just gets stronger. By Friday the 14th, the swell hits 8ft and the wind is blowing 22-25 mph, so the ocean is just a washing machine. The combined energy climbs into the strong zone, hitting (1388) that afternoon, but it’s all blown out. Then the weekend of the 15th and 16th gets properly nasty – we’re talking storm level. Saturday the 15th has a 23ft swell with a period of 12 seconds and wind screaming at 31 mph. That is a massive (14042) of energy, but with a “risk tstorm” tag and near-gale winds, this is strictly for experts or, more realistically, kite surfers if they’re crazy enough. That big, long-period groundswell will be breaking too straight for Kailua Beach anyway.

The wind eases a touch into the next week, but it’s still onshore or cross-onshore, keeping the surf choppy. The swell stays in the 6ft to 7ft range with moderate energy (300-700), but the quality is just not there.

The first flicker of hope comes on Thursday morning the 20th of August. The wind finally drops to a gentle breeze at 9 mph, and the combined energy is up to a moderate (508). The wave comment says "marginal," scoring a 1 out of 10. It’s a gentle cross-onshore, so it’ll be a bit choppy, but with the swell at 4ft from the E with an 8-second period, it might just be the most rideable thing we’ve seen in two weeks. It’s not a standout, it’s just the least bad option.

The rest of the period into the 23rd stays poor. The trades pick back up, the surf gets messy again.

Honestly, for the next 16 days, there is no true standout session. If you’re desperate, Thursday morning the 20th is your only real chance to get a few grovelly ones. Otherwise, I’d save the energy and wait for a change in the pattern. It’s a long, flat spell of blown-out junk.

Rusty.
