The Lowdown
Alright folks, Rusty here. Let’s talk about Kailua Beach for the next couple of weeks. I’m gonna be honest – it’s a bleak outlook. We’re looking at a full 16-day window, and there’s barely a glimmer.
Kailua Beach is a point break that’s fairly consistent, exposed to the NE, and that’s the direction we want. The water’s sitting at about 80°, which is just a hair above average for this time of year, so no surprises there.
The big problem is the wind. Starting Saturday the 1st, it’s a grinding ENE breeze, blowing onshore or cross-onshore, from 9 mph all the way up to 22 mph. That’s chopping everything up. The swell is mostly ENE, ranging from around 3 ft to 8 ft, but the period is short – mostly 7 to 8 seconds – so it’s weak, wind-blown mess. The combined energy figures are all in the low to mid hundreds (1020 down to 90), which tells you the ocean just doesn’t have any real power.
Tuesday morning the 4th is the only tiny window that’s even worth a mention. We get a 5 ft ENE swell with a period stretching to 11 seconds, and a gentle breeze. The energy hits 534, which is moderate, but even then the call is just “marginal.” That’s the only session that scrapes a 1 out of 10. After that, it’s non-stop poor surf and lumpy conditions all the way through Sunday the 16th. Nothing stands out. No real options.
If you’re into kite surfing, that steady wind might be your thing, but for hanging on a surfboard? Hard no. Don’t bother fighting the onshores for blown-out, short-period slop. It never stays this bad forever around here, and forecasts can flip, but right now, you’re better off taking a break.
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.
