Kailua Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

Right off the bat, I gotta be straight with you – we’re looking at a pretty barren run here. The whole sixteen-day window is a bit of a write-off for decent surf. There's not a single moment I'd call good, and the conditions are just going to be a battle from start to finish. We’ve got a long stretch of poor surf ahead.

Let's start with Kailua Beach (Oahu). The water temp is sitting at a warm 81°, which is bang on average for this time of year, so no surprises there. But that’s where the good news ends. From Saturday the 29th of August right through to the end of the first week, we’re dealing with a relentless ENE tradewind. It’s blowing at 19 to 22 mph, and it’s either cross-on or straight onshore, which is just going to chop everything to pieces. The swell is hanging around 5 ft to 7 ft with a short, weak period of 6 to 8 seconds, and the combined energy is weak to moderate at best (298 to 504). The wave comment says it all: "poor surf conditions." It’s not going to be any fun out there.

Moving into the second week, things actually get bigger, but not better. Around Saturday the 5th of September, we see the swell jump up to 10 ft to 12 ft with a still short 8-second period, and the energy climbs into the strong range (1014 to 1497). The wind is still howling onshore at 25 mph. This is getting into expert-only territory size-wise, but with that onshore wind, even the experienced guys are going to have a tough time. It might actually be more interesting for the kite surfers than us paddle guys.

Then on Sunday the 6th of September, the real juice shows up. We’re talking a 16 ft swell from the E with an 11-second period and a massive combined energy of 5766. That’s a lot of power, but the wind is a strong cross-onshore at 28 mph. That’s a recipe for a total mess. The setup at Kailua is a beach/point, so with that much size and that wind, it’s going to be a washing machine. No good for us.

The rest of the second week settles down a bit, but the winds stay onshore or cross-onshore, and the swell stays in the 5 ft to 8 ft range with short periods. The combined energy is moderate to strong, but the "poor surf conditions" tag keeps popping up. There’s just no window of clean, calm conditions to make anything work. Honestly, it’s one of those stretches where you might as well find something else to do. The forecasts can always change, but as it stands, I wouldn’t bother waxing up for a while.

Rusty.
