G’day, Rusty here. I’ve sifted through what’s coming up for Kailua Beach over the next couple weeks, and I gotta say—it’s a tough stretch. The whole 16-day window is a complete bust, with not a single session worth wetting a wetsuit for. No standout days, no hidden gems, just a flat-out “poor surf conditions” on every single report. That’s a rough one.
So, what’s going on? Kailua Beach is a point break, pretty consistent and open to the NE, which is the sweet spot direction for it. But from Sunday morning, July 5th, right through to Monday afternoon, July 20th, it’s a total dud. The swell hangs between 6 ft and 8 ft—size is actually there, but the wind is the spoiler. An endless ENE breeze blowing 12 to 22 mph, mostly onshore or cross-onshore, keeps things messy, lumpy, and choppy. The wave period is short—7 to 8 seconds—so it’s weak, wind-blown junk, not real groundswell. The combined energy numbers sit in the moderate range (241 to 592), but it’s all noise with zero quality.
Water temp at the start is about 80°F, which is pretty average for this time of year—nothing unusual there, just warm tropical water you won’t want to fight that wind for.
Honestly, for paddle surfing, this stretch is a full skip. With that steady wind and the swell size, this setup looks way more interesting for kite surfing than anything with a paddle. The silver lining? This break is usually fairly consistent, so a blank run like this isn’t the norm—forecasts can shift—but right now, there’s nothing to chase. Best to leave the stick at home and wait for a better day.
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.
