The Lowdown

G’day, Rusty here. Let’s talk about Kailua Beach for the next couple of weeks. I’ll be honest, this forecast is a tough one—most of it’s a bust, and you’ll be waiting a while for anything worthwhile.

The only real standout is Wednesday morning, 29 July. That morning, we’ve got a clean 7ft swell coming from the ENE with a period of 10 seconds, and the wind is dead calm—glassy as it gets. Water temperature’s about 80°, which is pretty average for the season. The combined energy is moderate (821). It’s a point break that’s exposed to the swell and fairly consistent, so you can expect some decent waves. It does get crowded sometimes, so plan for company. That morning session is your golden window.

Now for the rough stuff. From Monday afternoon, 27 July, through Tuesday, 28 July, it’s all poor surf with onshore winds. Tuesday afternoon sees 7ft of messy E swell and a moderate cross-onshore breeze—skip it. After that Wednesday morning glass-off, it goes downhill fast. From Thursday, 30 July, all the way to Tuesday, 11 August, it’s a relentless run of poor conditions—cross-onshore winds, lumpy, choppy, messy. Swell hangs between 4ft and 8ft, but with short periods of 7 or 8 seconds and fresh to strong breezes, it’s blown out. Combined energy stays moderate (217 to 983). This setup looks better for kite surfing than paddle surfing.

Even the longer-period swell around 4 and 5 August (11 to 12 seconds) doesn’t save it—wind’s still moderate and cross-onshore. From 6 August onward, swell picks up to 7ft–8ft, but with fresh cross-onshore winds, it’s lumpy and messy.

There’s a tiny chance on Tuesday morning, 11 August, with a 5ft NE swell and a light breeze, but it’s only marginal.

Bottom line: Wednesday morning, 29 July, at Kailua Beach is your one true shot. Get out early, enjoy the glass, and hope for a few clean ones. The rest is a long stretch of poor surf. Forecasts can change, but right now, it’s grim.

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.
