Hey, it's Rusty. Looking at Kailua Beach for the next 16 days, and I hate to be the bearer of bad news, but this is pretty grim for surfing. The trades are locked in from the ENE, blowing 15 to 22 mph the whole time, making a mess of the ocean.
Water temp is about normal for this time of year. The swell is coming from the ENE – not the right angle for this point break. Swell sizes run from about 5 ft down to 3 ft, with combined energy starting at 302 (moderate) and peaking over 500 (strong) around July 6th and 7th, but it’s all short-period windswell, 7 to 8 seconds. Every single report calls it “poor surf conditions.”
From July 3rd through July 11th, we’re looking at 5 to 7 ft of onshore junk. Do not bother. The wind is ruining everything.
There is a slight shift around July 11th and 12th, with swell backing off to 3-5 ft and coming more from E and then NE, which is Kailua’s optimum direction from the guidance. But the period stays short at 7-8 seconds, and the wind is still cross-on or on. The energy drops to weak territory, 208-289. Still no good surf.
Into the second week, from July 14th onward, the swell collapses. Heights drop under 3 ft, periods fall to 6 seconds, and energy goes all the way down to 74 (weak). The wind just keeps blowing.
There are zero good days in this forecast. Not one. The consistency might be “fairly consistent” for this break, but with this wind, a stretch like this is more normal for the area. It’ll come good again eventually, forecasts change. But right now, unless you’re on a kite, there’s nothing for a surfer here.
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.
