Kailua Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a hard look at what’s coming down the pipe at Kailua Beach (Oahu). Normally, this point break can be a gem, but this 16-day stretch is a tough one to call. The water temp is 81°, sitting about average for this time of year, so that's one small blessing.

Straight up, the first few days are a write-off for decent waves. The swell is tiny, the wind is mostly onshore or cross-onshore, and the wave comment keeps telling us conditions are poor. Sunday the 13th has a weak 3 ft NE swell (178 combined energy), but that onshore ENE wind just kills it. Monday the 14th and Tuesday the 15th are the same story – small, choppy, and messy. We’re looking at a real gap with no recommendations until maybe the end of the week.

Things finally start to show a pulse on Thursday the 17th. We get a 7 ft to 7 ft ENE swell pushing through. But here’s the kicker: that swell is short-period (7 seconds) and the wind is cranking onshore at 19 mph from the ENE. That combo is basically a washing machine. The combined energy climbs up to 486 (moderate) by Thursday afternoon, but it's just not surfable in any fun way. For experienced guys only, and even then, it’s a battle.

Friday the 18th through the weekend stays similar – 6 ft to 7 ft ENE/E swells. Periods hover around 8 seconds, which is still pretty average, and the wind doesn't ease up. It’s a 16-19 mph cross-onshore mess, churning up lumpy, choppy lines. These are not the clean, peeling walls you’re after at a point break. Honestly, if you had a kite, this might be more your scene than a paddle board.

As we push into the second week, there’s one day that catches the eye. Wednesday, 23rd September is the standout, and I mean the *only* standout. We’re looking at a 7-8 ft E swell with a longer period hitting 11 seconds. The combined energy gets strong, reaching 1317 by the afternoon. This is real groundswell energy. The problem is the wind is still a firm 16-19 mph from the ENE, keeping the cross-onshore chop in play. It’s going to be big, powerful, and raw – for experts only. If you can deal with the bump, there could be some heavy, fast sections. But it’s not the clean, glassy day you dream of.

After that, the swell drops off through the 24th and 25th. Then on Saturday the 26th, something strange pops up – a 2 ft NW swell with a very long 18-second period (439 combined energy). That’s a long-range pulse, but it’s tiny and weirdly directional for this break. It’ll be flat and wonky.

The final few days from the 27th slip back into the same onshore, choppy pattern with 5 ft to 6 ft ENE swell. Nothing to get excited about.

So, the honest truth: this is a grim window for Kailua Beach. The wind just won’t play ball. The one shot at some decent size and energy is around Wednesday the 23rd, but only if you’re an expert and don’t mind it blown-out and lumpy. For most of us, it’s a long wait for a clean day that just isn’t here. The forecasts can change, but right now, I’d leave the boards at home for a bit.

Rusty.
