Alright, Rusty here, and I'm spitting it straight about Kailua Beach. It's a tough outlook, friends. For the next two weeks, we're in a drought of clean waves. The combined swell energy (e.g., 498) is there, but it's all just noise with the wind howling.
The wind is the enemy. From Monday, July 6th, all the way through, it's a solid 20-25 mph onshore breeze straight from the ENE. This is making the surf a blown-out, choppy, gutless mess. Don't even bother looking at the tide charts; the wind is ruining every session. The wave height is running 4 to 7 feet, which is a decent size, but with a short period of 7-8 seconds, it's just lumpy, fat lines with no push.
Every single report says "poor surf conditions." There's no break in the wind. For a point break like Kailua that needs a clean face, this is a write-off. With that steady wind and a beach-break setup, this is better for kiteboarding right now than paddle surfing.
Way out, on Monday, July 20th and Tuesday, July 21st, there's a spike in the swell period to 15-19 seconds. That's some proper groundswell energy, and the energy numbers jump (like 600 on the 20th). But here's the kicker: the wind is still cross-onshore, and the wave height drops to barely 2-3 feet. That combo of massive period and tiny height just won't produce anything rideable. It's a cruel tease.
So that's it. A blank 16-day run. No standouts. The best advice is to sit this one out. The swell is okay, but the wind has to change for anything to happen. Rusty out.

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.
