The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for Kailua Beach.
Straight up, the outlook for this 16-day window is a tough one for us surfers at Kailua Beach. This is a point break that's exposed to the swell, but it's got a real picky appetite for that NE optimum direction. The problem is, for the vast majority of the forecast, the wind is just blowing too hard from the wrong direction, turning what could be a fun session into a battle with the chop. There's a long stretch of marginal to poor conditions, especially from the 27th of July through to the 5th of August, where the wind is either onshore or a strong cross-onshore, and the wave quality is just not there. It's a real bummer, because the swell energy is actually moderate to strong for a lot of that, hitting values like 2123 on the 28th of July, but it's all wasted.
The only real glimmer of hope, the standout, is the 29th of July. Wednesday morning and afternoon are looking like the best on offer. We've got a decent 7.2ft swell from the ENE, with a moderate wave energy of 970. The wind is a light cross-offshore breeze from the SSE, which is going to clean things up nicely. The report says "expect very good surf conditions," and that's the call you want to hear. This is a point break, but with that swell direction and period of 10 seconds, it should shape up nicely, offering some fun, rideable waves. Just keep in mind, Kailua Beach can get crowded sometimes, so get out there early for the best of it.
After that, the wind turns nasty again. From the 30th of July onward, it's a relentless stream of ENE winds, often strong and cross-onshore, making the surf choppy and messy. The swell stays on the table, but the quality is shot. By the 6th of August, the swell drops right off, and the energy is weak, with values around 127. The second week of the forecast, into August, has some swell but it's all in the 4.9ft to 7.2ft range with terrible wind, making it more of a kite-surfing setup than a paddle-surfing one. There's no real light at the end of the tunnel in this forecast.
So, for the best surf, you’re looking at Wednesday, the 29th of July. That's your window.

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.
