The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Kailua Beach.

We’ve got a pretty grim run ahead, I’m not gonna lie. The whole 16-day window is basically a write-off for decent paddle surfing. The problem is relentless onshore and cross-onshore winds, mostly from the ENE, that just won’t let up. The water temp is sitting at a pleasant 80°F, which is bang on average for this time of year, so at least a swim won’t be a shock to the system.

We kick off Thursday morning, July 23rd, and the first week is a total bust. We’re looking at 7 ft of short-period, 7-second wind swell from the ENE, but it’s all messy and lumpy with a 22 mph cross-onshore wind. The energy is weak, sitting at 340, and it’s just a choppy, ugly mess. This theme continues right through the weekend and into the start of the following week. The swell gets a bit bigger, but it’s all blown out. The wind is always on it, and the wave comment is consistently “poor surf conditions.” There’s nothing to get excited about here.

We do see a spike in energy on the 28th of July, with the combined energy hitting 1345, but it’s a 7 ft ENE swell with a 12-second period and a 16 mph onshore wind. That’s a lot of churning white water, but it’s unsurfable. The only semi-interesting window is around Wednesday, July 29th. The swell is up to 10 ft from the ENE, with a period of 10 seconds and a cross-offshore wind from the SSE. The energy is strong at 1773, and the report says “clean.” The trouble is, that’s a solid 10 ft wave, which is strictly for experts only. It’s also a “marginal” call due to tide or other factors. Kailua Beach is a point break, but with that much ENE swell, it’s going to be a beast. The wind is decent, but the size makes it a no-go zone for most of us.

After that, the wind swings back onshore and the surf quality drops off a cliff again. The second week is more of the same. We get a bit of a pulse around the 5th of August, with 7 ft and 7 ft ENE swell and a 12-second period, but the wind is still onshore and the report calls it “marginal.” The energy is strong (1236), but it’s just not going to be clean. The final days of the forecast are back to small, weak, and choppy.

Bottom line: there’s no standout session here. The wind is the villain. For a spot that’s “fairly consistent,” this is a real drought. If you’re a kite surfer, that 10 ft day on the 29th with cross-offshore wind might look interesting, but for a paddle surfer, it’s a hard pass. Keep the board in the car and wait for the forecast to change.

Information about the Kailua Beach Surf forecast

The above surf forecast table for Kailua Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kailua Beach can be found by selecting the local surf guide option on the grey menu. Our Kailua Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kailua Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kailua Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
