Kailua Beach Surf Forecast and Surf Report

Alright, Rusty here again, switching to feet and miles for you. Let’s break down Kailua Beach.

It’s a tough start. We’re looking at a solid week of blown-out junk before we finally get a clean window. The first real chance isn’t until Tuesday the 8th, and even then, it’s a marginal call.

From Thursday the 3rd through Monday the 7th, it’s all poor surf. The wind is hammering from the ENE at 20-22 mph, making everything lumpy and ugly. The swell is there, but it’s trash. Monday the 7th sees a big spike in energy, with a combined swell energy of 2560, but with a cross-onshore wind and 10-foot stormy swell, that’s for experts only, and it’s messy. That’s more of a kite-surfing day than a paddling one.

We get a break on Tuesday the 8th. The wind swings to a light SSW cross-offshore at 9 mph in the afternoon, cleaning things up. The waves are small, around 4 feet, but the clean conditions are a relief. Combined energy is a modest 364, so it’s gentle, but it’s rideable.

Then we get the real standout. Wednesday morning, the 9th of September. That’s the one to mark. The wind drops to nothing – glassy, at 3 mph from the NNE. The swell is only 2 feet, but it’s pure, long-period groundswell from the east with a period of 14 seconds. The combined energy is 467, and with the glassy conditions, Kailua Beach will be offering up some clean, fun little waves. The water temp is about average for the time of year. This is the best on offer, but it’s a short window, as the wind kicks back onshore by the afternoon.

After that, it’s back to the grind. From Thursday the 10th onward, the wind turns onshore again, and the surf quality drops. The swell gets bigger, with some serious energy pumping in around the 14th and 15th (combined energy hitting 2935 and 4855), but it’s all blown out. Those 15-foot waves on the 15th are huge and dangerous, with a fresh onshore wind. For the rest of the 16-day outlook, it’s the same story: waves, but bad conditions. The long-range stuff is too uncertain to get excited about.

So, the takeaway: if you want a clean wave, you’ve got to wait for that glassy Wednesday morning. Otherwise, it’s a long, frustrating wait for the onshore wind to ease up.

Rusty.
