The Lowdown

Alright, folks, Rusty here. Let's be straight with you, looking at the forecast window for Kailua Beach over the next sixteen days. I gotta tell ya, it's a tough one. This spot is a point break, exposed to the swell, but the dominant wind pattern we're seeing is just gonna be a problem. For pretty much the entire first week and a half, the wind is howling from the east-northeast, smack onshore or cross-onshore, and that just kills any chance of a clean wave out there.

From Friday the 17th right through to Tuesday the 29th, it’s a long, frustrating run of "poor surf conditions" with scores that don't even register. The combined swell energy is weak to moderate, but it doesn’t matter when the wind is ruining every face. The waves are there, between 2ft and a little over 6ft, but they’ll be choppy, lumpy, and messy. A classic case of "looks can be deceiving" from the beach. For the beginner or intermediate surfer this spot is meant for, this is a write-off.

We do finally see a flicker of promise, but it's a long way off. On Wednesday the 29th and into Thursday the 30th of July, the swell gets a bit more grunt. We’re looking at waves in the 6ft to 7ft range, with a better period of 12 to 13 seconds. The combined energy jumps right up, showing there's real power in the water. The wind even eases off to a gentle to moderate breeze, and we get some "on" shore winds. The forecast still calls it marginal, but at least there's a glimmer of hope.

Honestly, for the whole sixteen-day run, there are zero standouts. The wind is the enemy here, plain and simple. If you’re desperate for a paddle on the 29th or 30th, keep your expectations on the floor. The water temp is about average for this time of year, so at least you won't be cold while you're getting blown off your board. It's a swing and a miss for July.

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.
