Alright folks, Rusty here. Let’s break down what’s on offer for the next couple of weeks.
Straight up, the outlook for Kailua Beach is a bit of a bummer. We’ve got a solid run of swell on the way, but the wind is just not playing ball. For the entire 16-day window, every single surf session is marked as "poor surf conditions," so there are no standout days. The first recommendation isn’t even a recommendation, it’s just the first record of the period, kicking off Saturday afternoon, July 4th.
The issue is that persistent ENE wind – often a fresh breeze of 18 to 22 mph – is blowing either directly onshore or cross-onshore for most of the period. That’s going to chop things up and make for lumpy, messy conditions all the way through. The swell is there, ranging from 4 ft to 8 ft, with moderate combined wave energy (values between 127 and 607), but the wind quality kills it. The swell period is mostly short, under 8 seconds, which adds to the choppy feel.
The only potential silver lining comes way down the line. In the second week, around July 17th and 18th, the wind eases back to a moderate breeze of 12 to 15 mph and starts blowing more directly onshore but from the ENE. Still, the wave comment stays "poor" and the period drops to 6-7 seconds. It’s a long gap of nothing but marginal, blown-out surf. If you’re desperate, these days might be the least bad of a bad bunch, but don’t expect any quality.
With the consistent onshore wind and solid but choppy swell, this setup honestly looks more interesting for kite surfing than paddle surfing. The water temperature is a very normal 79°F, about average for this time of year.
Hang in there, gang. Sometimes it’s just like this.
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.
