The Lowdown

Alright folks, Rusty here. Let’s get into what’s on offer for Kailua Beach over the next couple of weeks. I’ll be straight with you – it’s a tough stretch.

We’ve got a lot of energy in the water across the period, but the wind is going to be the story here, and unfortunately, not a good one for paddle surfing. The combined energy from the E/ENE swells is often moderate to strong, hitting values like 1847 and 1054 at times. But that's cold comfort when the wind is blowing so strong and cross-onshore. The water temp is sitting about 80° at the start, which is pretty much normal for the time of year. Not much to get excited about.

Starting off on Tuesday the 28th, we’ve got a 7ft E swell running with a 13-second period, which has a bit of groundswell in it. That would be a good setup at a point break, but here at Kailua Beach, the cross-on breeze is 16 mph out of the NNE, making for a choppy, messy mess. The score is a zero for surf quality. Wednesday the 29th offers a glimmer of hope in the afternoon – the swell drops to 5ft from the ENE, the wind swings onshore at a lighter 6 mph, but it’s only rated as a marginal call. Still, that’s the best we’ll see for a while.

From Thursday the 30th all the way through to Wednesday the 12th of August, it’s a grim run of poor surf conditions. The wind is relentless – either a fresh to strong breeze out of the ENE or NE, cranking at 16 to 25 mph, always cross-onshore or onshore. The swell direction stays mostly locked in from the ENE, but the period is often short, around 6 to 9 seconds. The wave heights bobble around from 4ft up to 8ft, but with that kind of wind, it’s just bumps and chop. Nothing worth paddling out for. The combined energy stays moderate, dropping as low as 109 on Monday the 10th, showing the wave power is just weak and disorganised.

There is a slight uptick on Tuesday the 4th of August morning, where the combined energy hits 689 with a 5ft swell from the ENE at a longer 12-second period, but the breeze is still a gentler cross-onshore. It's another "marginal" call, but with the wind still from the wrong quarter, it’s tough to recommend. After that, it’s right back into poor conditions.

Bottom line: with these strong cross-onshore winds and a beach setup, this is looking far more interesting for a kite surfer than a paddle surfer. The long-range end, from the 9th to the 12th, is quiet and weak. I wouldn’t hold my breath for this one. Forecasts can change, but right now, Kailua’s not playing ball for us.

Rusty.

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.
